Parts 1–3 covered the market, the TWAP60 target, and the slot lifecycle.

This last post is about evidence, limits, and what you should not expect from the public repo.

1. What the Public Sample Shows

From the project README and public trade windows:

Resolved-book sample (150 markets, entries near 50¢)

Metric	Value
Held-side win rate	60.7% (91W / 59L)
ROI on capital at resolution	≈ +24.5%
Average held entry	~0.50

Broader activity sample (~5,000 trades)

Metric	Value
BTC share	~99%
5-minute share	~96%
Fills in 45–55¢	~90.6%
Buy / sell mix	72.9% / 27.1%
Median clip	~$58
Round-tripped scratches	~930 at ~0 spread
Median buy / sell time	~47s / ~226s after open

The useful interpretation:

The win rate is on the filtered book that reached resolution
Scratches are visible in the sell-side volume
This is a specialist BTC 5m system, not a multi-market spray

2. What Those Numbers Do Not Prove

They do not prove:

lifetime audited PnL
that every future month will look like the sample
that copying src/ will reproduce ~60.7%
that the edge survives every volatility regime
that size can scale linearly

They do support a narrower claim:

The account behaves like a mid-band directional engine with active culling, not like a 94–99¢ convergence farm.

That distinction is already useful.

3. Economics Without Marketing Fog

For a binary held to $1 at entry ( p \approx 0.50 ) and win rate ( w ):

[
EV \approx 0.50 \times (2w - 1)
]

At ( w = 0.607 ), naïve EV is about +10.7% of stake per resolved ticket.

The higher sample ROI can appear because:

some winners were accumulated below 0.50
many losers were scratched before becoming full $0 outcomes

That is process, not magic.

4. Real Risks After TWAP60

Signal risk

Without a genuine short-horizon read, 50¢ trading is coin-flipping minus costs.
Latency / adverse selection

Slow infrastructure buys the wrong side after the move is already in the book.
Regime decay

Crowded 5m books and volatility shifts can erase old calibration.
Scratch-cost risk

“Breakeven exit” assumes depth near 50¢. Thin books charge real spread.
Settlement-target drift

Live 5-minute crypto now settles on 60-second Chainlink TWAP. Any leftover snapshot or 30s logic is a silent mismatch.
Sample-window risk

150 resolved markets and 5,000 trades are evidence of style. They are not a guarantee.

5. What Is Public vs Private

Public

Strategy archetype
Execution shell
TWAP-aligned architecture
Wallet / profile / fill footprint
TypeScript reference:
- twapFeed.ts
- signal.ts
- engine.ts
- clob.ts
- markets.ts
Windows trial binary (Abrownfox001.exe)
Session walkthrough video

Private

The calibrated 5-minute probability model
Exact feature weights
Live threshold schedule
The part that actually turns a coin-flip book into a ~61/39 settled book

This split is intentional. Publishing the signal would compete the edge away. Publishing the architecture lets other builders avoid the dumb mistakes.

6. How to Verify Independently

curl "https://gamma-api.polymarket.com/public-profile?address=0x12b712029efeee7efc4066e98e4e1b6beb8b1b0b"
curl "https://data-api.polymarket.com/trades?user=0x12b712029efeee7efc4066e98e4e1b6beb8b1b0b&limit=1000"

Also:

Profile activity tab
Video walkthrough of the live session
Repo + executable for the public shell

Verification ≠ disclosure.

7. If You Are Building Your Own Version

Rebuild the shell first:

Stream 60s TWAP
Pin open reference from the same series
Score continuously
Enter only in 45–55¢ when edge exists
Scratch decaying tickets
Redeem winners
Log window, open TWAP, final TWAP, and resolution source every slot

Then be honest:

without your own alpha, you have a disciplined coin-flip machine.

8. Series Recap

Part 1: BTC 5m is a forecasting problem, not a last-tick casino
Part 2: Settlement is 60s Chainlink TWAP; the signal must target that path
Part 3: Edge is execution as much as prediction — stagger, re-score, scratch
Part 4: Public data supports the style; the live read stays closed; risks are real

One-line version of the whole system:

Forecast the official TWAP path, buy it only near fair value, and refuse to carry weak tickets to resolution.

Enter Fair, Scratch Weak, Redeem Strong

ABROWNFOX001 — Tue, 01 Sep 2026 13:29:08 +0000

GitHub: https://github.com/abrownfox0/abrownfox001-twap60-prediction-trigger-system

YouTube walkthrough: https://www.youtube.com/watch?v=XzhugRL6BV4

Part 2 produced a TWAP60-aligned P(up).

This post is the execution layer. A correct probability is useless if you overpay, overhold, or never cut a decaying ticket.

Live profile: @abrownfox001

1. The State Machine

Every active btc-updown-5m-* market runs one lifecycle:

SlotOpen
  → Wait for edge
  → Accumulate in 45–55¢
  → Re-score every 10–30s
       ├─ conviction decayed → Scratch ~breakeven
       └─ conviction intact  → Hold
            → Redeem winner at $1

This is directional micro-forecasting + risk culling.

Not market making. Not 99¢ farming.

The public shell for this loop lives in src/engine.ts and src/clob.ts.

2. Entry Rules

The engine buys only when both conditions are true:

|P(up) − 0.5| clears the edge threshold
The ask sits in the fair 45–55¢ band

Observed pattern from the README / public sample:

Item	Value
Typical clip	~$50–175
Per-slot cap	roughly $200–500
Average held entry	~0.503
Median buy time	~47 seconds after open
Fills in 45–55¢	~90.6%

Why not t=0?

Early books are often thin. Paying 53–55¢ for a ~50¢ fair value deletes the edge before the thesis starts.

Why stagger?

Entries are spread through the first half of the slot so the bot sources liquidity near 50¢ instead of lifting the whole offer.

3. The Re-Score Loop

After entry, the position is not “set and forget.”

Every 10–30 seconds the engine recomputes:

latest 60s TWAP vs open reference
updated P(up)
time remaining
whether the original thesis is still alive

That loop is the difference between an engine and a hope-and-hold script.

Under TWAP60 the path is smoother than a last-tick series. Re-scoring still matters. The thresholds just need to be retuned for the slower official average.

4. Scratch Exits Are the Second Edge

Most directional bots are only entry engines.

This system treats scratching as a first-class component.

Public footprint:

Buy/sell mix about 72.9% / 27.1%
~930 markets with buy and sell at almost the same price
Average scratch path: buy ~0.504 → sell ~0.503

Those sells are not profit-taking. They are conviction culls.

if signal decayed:
    taker sell back to flat
    recycle capital into the next live read
else:
    keep holding

Why this matters:

A raw 55–58% signal still bleeds if every weak loser is held to $0
Filtering can lift the resolved book toward ~60.7%
Capital turnover stays high on a 5-minute clock

After the 30s → 60s move, old scratch thresholds can become too twitchy. Re-estimate them on post-cutover data.

5. Timing Inside the Slot

Observed BTC 5m activity by seconds after open:

Bucket	Share
0–5s	6.3%
5–30s	16.6%
30–150s	35.7%
150–270s	26.1%
270–300s	15.3%

Interpretation:

Buys skew earlier — accumulate near fair value
Sells skew later (median ~226s) — cut decaying tickets as the slot matures

That is exactly what a re-score + scratch design should look like in public fills.

6. Hold-to-Resolution Path

Only tickets that keep clearing conviction stay open.

If the slot resolves in favor of the held side:

redeem at $1
that is where the main PnL is realized

The system does not depend on fancy mid-slot scalp math. PnL comes from:

fair entries
fewer full losers
winners that reach redemption

7. Execution Constraints That Actually Matter

At ~50¢, fees are not the main enemy. These are:

Fill quality — do not pay 3¢ extra just to be first
Latency — a slow loop buys the move after it is priced in
Book depth — “breakeven scratch” requires liquidity near 50¢
Idempotent orders — no double-sends when the socket blips
Per-slot caps — one hot slot should not consume the whole book

The public TypeScript shell implements discovery, CLOB routing, and the state machine. The live calibrated trigger remains private.

8. Code Map for This Layer

Module	Role in the lifecycle
`markets.ts`	Find the active BTC 5m slot
`engine.ts`	enter → hold → scratch → redeem
`clob.ts`	CLOB v2 orders
`signal.ts`	updated `P(up)` for each re-score
`config.ts`	size, thresholds, dry-run switches

Windows path: Abrownfox001.exe

Developer path: npm start (dry-run by default)

9. Common Implementation Mistakes

Entering immediately at slot open
Using one giant clip instead of staggered size
Holding every fill to resolution
Scratching too fast on a smoother 60s TWAP path
Scratching too slow after the thesis is already dead
Treating sell-side volume as “the strategy failed” instead of “the filter worked”

10. What Part 4 Covers

Architecture is not the same as results.

Part 4 covers:

public sample numbers and what they do / do not prove
risks after the TWAP60 cutover
why the signal stays closed
how to verify the live wallet independently

TWAP60 Is the Only Valid Target

ABROWNFOX001 — Tue, 01 Sep 2026 13:26:37 +0000

GitHub: https://github.com/abrownfox0/abrownfox001-twap60-prediction-trigger-system

YouTube walkthrough: https://www.youtube.com/watch?v=XzhugRL6BV4

Part 1 defined the engine: a BTC 5-minute specialist that buys near 50¢ and scratches weak tickets.

Part 2 is the target variable. If this layer is wrong, the rest of the stack is just a fast way to lose money.

Live profile: @abrownfox001

1. What Polymarket Pays Now

Short crypto Up/Down markets no longer resolve on a single snapshot.

They settle on Chainlink TWAP.

Market	Settlement window now
BTC 5-minute	60-second TWAP
15-minute crypto	60-second TWAP
4-hour crypto	60-second TWAP

5-minute markets originally launched with a 30-second window. Markets deployed since August 14, 2026 use 60 seconds. The repo name is explicit: twap60-prediction-trigger-system.

The README still mentions 30s in older module notes. Live 5m production should treat 60s as the official series.

Important: 60 seconds is a lookback window, not how often a new report arrives.

2. The Question the Bot Must Answer

Wrong question:

Where will Binance print at the close?

Right question:

Where will the official 60-second average sit versus the slot-open reference?

A brief wick can flip a snapshot market and barely move a 60s average.

A grind that holds through the lookback can decide settlement even if the last tick snaps back.

If the signal is trained on CEX last prices, it is forecasting a variable the market no longer pays.

3. The Only Clean State

For each btc-updown-5m-* slot:

twap_open = 60s Chainlink TWAP at slot start
twap_now  = latest 60s Chainlink TWAP
t_left    = seconds remaining

Everything else is auxiliary.

Useful extras:

CEX mid for lead-lag (cexFeed.ts)
flow / book imbalance
realized path volatility inside the slot

Not substitutes:

last Binance print
Coinbase close guess
leftover 30s TWAP on new 5m markets

Both the price-to-beat and the final score must come from the same 60s family. Mix windows and you invent false wins.

4. Signal Structure

The private layer outputs a continuous probability:

[
P(up)t = f(\text{TWAP path vs } twap{open},\ \text{lead-lag},\ \text{flow},\ t_{left})
]

Design rules used in the live stack:

Anchor to TWAP first. Direction versus open comes from the official series.
Use CEX only as lead-lag. It can move first. It must not replace settlement.
Make time-in-slot explicit. 52% at t=20s is not 52% at t=280s.
Keep the output calibrated. The number has to mean probability.
Never mix windows. Open pin, live score, and resolution labels stay on 60s.

The exact formula stays private. That is the moat. The structure does not need to be secret.

5. Reference Code Map

Module	Job
`src/twapFeed.ts`	Stream official TWAP via Polymarket RTDS
`src/signal.ts`	Convert TWAP path vs open into `P(up)`
`src/cexFeed.ts`	Auxiliary mid for lead-lag
`src/engine.ts`	Consume the probability and run the slot

Production feed path:

RTDS 60s topic / SDK windowSeconds: 60
exact filter form {"symbol":"btc/usd"}
freshness checks on observation timestamps
exact decimal / bigint handling — no sloppy floats for settlement math

If the TWAP is stale, skip the slot. Do not invent a substitute from spot.

6. The Trade Gate

The engine does not trade every twitch of the model.

if abs(P(up) - 0.5) < threshold:
    wait
if ask not in 45–55¢:
    wait
else:
    accumulate small clip

Edge without a fair price is overpaying.

A fair price without edge is a coin flip.

7. What the 30s → 60s Cutover Changed

The target series got smoother
Fast spike features lost power
Open-reference mismatch became a silent killer
Scratch thresholds needed retuning
Snapshot and 30s leftovers became research-only

That is why this series treats TWAP60 as the first engineering problem, not a footnote.

8. Failure Modes in the Signal Layer

Pinning twap_open from the wrong feed
Scoring 60s live while labeling on 30s or CEX close
Treating socket heartbeat as proof of freshness
Letting CEX mid dominate P(up)
Trading raw model output with no threshold
Accepting a stale TWAP because “the websocket is still up”

If this layer is wrong, no entry trick saves the book.

9. What Part 3 Covers

Once P(up) exists, the hard part becomes mechanical:

when to enter
how not to lift a thin book
how often to re-score
when to scratch
when to let a ticket reach resolution

That is the slot lifecycle.

A Live BTC 5-Minute Engine Built for TWAP60

The Current Problem

Polymarket BTC 5-minute Up/Down books still sit near 50¢.

Most traders treat that as proof the market is random. Most bots then do one of three things:

Ignore 5-minute markets
Chase the last CEX tick
Abandon the mid-band and farm 94–99¢ tickets instead

That was already the wrong map. After August 2026 it is worse.

5-minute crypto markets now settle on a 60-second Chainlink TWAP, not a snapshot and not a leftover 30-second window. If your bot is still aiming at “where Binance prints at the close,” it is forecasting a number Polymarket no longer pays.

The Design Bet

The engine makes one concentrated bet:

Specialize in BTC 5-minute markets.

Anchor every decision to the official TWAP path.

Enter only near fair value.

Cull decaying positions in real time.

One line from the repo:

TWAP-anchored 5m BTC direction, executed at fair 50¢, with scratch exits that cull weak tickets so the settlement book is mostly the good reads.

Not a Convergence Farm

	Typical 94–99¢ farmer	abrownfox001
Price zone	Near-certainty	45–55¢ (~90% of fills)
Edge source	Structural certainty	TWAP-path directional forecast
Monetization	Tiny clip × huge volume	Filtered ~61% held-side book
Exit	Hold almost everything	Scratch weak / redeem strong
Universe	Mixed markets	BTC 5m specialist

Public resolved sample in the README (150 markets, entries near 50¢, Jul 2026):

Held-side win rate: 60.7% (91W / 59L)
ROI on capital at resolution: ≈ +24.5%
Average held entry: ~0.50

Read that correctly: those stats describe the filtered book that reached settlement, not every temporary fill.

The Three Jobs the System Has to Do at Once

1. Calibrated 5-minute signal (private)

Compare live Chainlink TWAP against the slot-open reference. Add lead-lag, flow, and time-in-slot. Output a real P(up), not a CEX color.

2. Fair-value entry

Observed pattern: mean entry ~0.503, clips $50–175, median buy ~47 seconds after open. The point is to source 50¢ liquidity instead of lifting a thin t=0 book.

3. Breakeven conviction culling

In the public window, ~930 markets show buy and sell at almost the same price (0.504 → 0.503). Those are scratches when conviction dies. Only strong reads ride to $1.

Miss any layer and 50¢ trading becomes coin-flipping minus fees.

What Is Public Right Now

Live profile and wallet footprint
Video walkthrough of the session
Windows binary: Abrownfox001.exe (2-day trial)
TypeScript shell: engine.ts, twapFeed.ts, signal.ts, clob.ts, markets.ts
Dry-run via npm start

What stays closed: the calibrated 5-minute probability. That is the moat. The repo is the architecture, not a drop-in replica of the live read.

Why This Series Starts Here

Before TWAP, latency, scratch thresholds, or Kalshi comparisons, one question has to be settled:

Is this a last-tick casino bot, or a settlement-aligned 5-minute forecasting engine?

abrownfox001 is the second thing.

Part 2 gets specific about the target variable: how 60-second Chainlink TWAP works, why open pinning must use the same series, and how the signal stack is built against that path.

Evidence, Limits, and the Private Layer

Parts 1–3 covered design, TWAP60, and execution.

Part 4 is what you can verify — and what you should not expect from the public repo.

Live profile: @abrownfox001

Wallet: 0x12b712029efeee7efc4066e98e4e1b6beb8b1b0b

Public Sample

Resolved book (150 markets near 50¢)

Metric	Value
Held-side win rate	60.7% (91W / 59L)
ROI at resolution	≈ +24.5%
Avg held entry	~0.50

Activity window (~5,000 trades)

Metric	Value
BTC / 5m share	~99% / ~96%
45–55¢ fills	~90.6%
Buy / sell	72.9% / 27.1%
Median clip	~$58
Scratch round-trips	~930 at ~0 spread
Median buy / sell	~47s / ~226s

This supports a style claim: mid-band directional engine with active culling.

It does not prove lifetime audited PnL, future months, or that cloning src/ reproduces 60.7%.

Economics

At entry ( p \approx 0.50 ) and held win rate ( w ):

[
EV \approx 0.50 \times (2w - 1)
]

At ( w = 0.607 ), naïve EV ≈ +10.7% of stake per resolved ticket.

Sample ROI can print higher because winners are often bought a bit under 0.50 and losers are scratched before $0.

Risks After TWAP60

No real signal → coin-flip minus costs
Latency / adverse selection
Regime decay and crowded 5m books
Thin-book “breakeven” scratches that are not breakeven
Silent 30s / snapshot leftover vs live 60s settlement
Sample-window overconfidence

Public vs Private

Public: architecture, execution shell, wallet, video, Windows trial, TypeScript modules.

Private: calibrated 5m probability, live thresholds, feature weights.

That split is the point. Publishing the signal competes the edge away. Publishing the shell stops people from rebuilding the dumb mistakes.

If You Rebuild the Shell

Stream 60s TWAP
Pin open from the same series
Score continuously
Enter only in 45–55¢ when edge exists
Scratch decay
Redeem winners
Log window, open TWAP, final TWAP, resolution source

Without your own alpha, that shell is disciplined coin-flipping.

Series Recap

Specialist BTC 5m engine, not a 99¢ farm
Target is live TWAP60, not CEX last
Execution edge is stagger + re-score + scratch
Public data shows style; the live read stays closed

One line:

Forecast the official TWAP path, buy it only near fair value, and refuse to carry weak tickets to resolution.

Enter Fair, Scratch Weak, Redeem Strong

ABROWNFOX001 — Mon, 31 Aug 2026 08:08:01 +0000

GitHub: https://github.com/abrownfox0/abrownfox001-twap60-prediction-trigger-system

YouTube walkthrough: https://www.youtube.com/watch?v=XzhugRL6BV4

Part 2 produced P(up) against TWAP60.

Part 3 is the slot machine that decides whether that probability ever becomes a settled ticket.

Live profile: @abrownfox001

State Machine

SlotOpen
  → wait for edge
  → BUY in 45–55¢
  → re-score every 10–30s
       ├─ decayed → scratch ~flat
       └─ intact  → hold → redeem $1

This is directional micro-forecasting plus risk culling.

Not market making. Not 99¢ farming.

Entry

Trade only if:

|P(up) − 0.5| clears threshold
ask is inside 45–55¢

README / public-sample pattern:

Item	Observed
Clip	~$50–175
Per-slot cap	~$200–500
Mean held entry	~0.503
Median buy	~47s after open
Mid-band share	~90.6%

Do not lift the first 5 seconds of a thin book. Paying 54¢ for a 50¢ thought deletes the edge.

Re-Score

After entry, nothing is “set and forget.”

Every 10–30 seconds recompute:

latest 60s TWAP vs open
updated P(up)
time remaining
whether the original thesis is still alive

That loop is the difference between an engine and a hope script.

Scratch Is the Second Edge

Public footprint:

buy/sell mix 72.9% / 27.1%
~930 round-trips at ~0 spread
avg scratch path 0.504 → 0.503
sells cluster later (median ~226s)

Those sells are conviction culls. They are why a raw 55–58% signal can become a ~60.7% resolved book.

After TWAP60, retune scratch. A smoother official series makes old 30s decay thresholds too twitchy.

Intra-Slot Timing

Seconds after open	Share
0–5	6.3%
5–30	16.6%
30–150	35.7%
150–270	26.1%
270–300	15.3%

Buys earlier to source fair liquidity.

Sells later to cut dying tickets.

Execution Constraints

At ~50¢ fees are secondary. Binding constraints:

fill quality
latency
depth for true breakeven scratches
idempotent CLOB orders
per-slot caps

Implemented in engine.ts + clob.ts. Live trigger remains private.

What Part 4 Covers

What the public sample proves, what it does not, and why the signal stays closed.

ABROWNFOX001 — Mon, 31 Aug 2026 08:06:32 +0000

GitHub: https://github.com/abrownfox0/abrownfox001-twap60-prediction-trigger-system

YouTube walkthrough: https://www.youtube.com/watch?v=XzhugRL6BV4

Part 1 defined the engine.

Part 2 is the settlement target the engine is built to predict.

Live profile: @abrownfox001

Current Rule

Polymarket short crypto Up/Down markets settle on Chainlink TWAP.

Duration	Current window
5-minute	60-second TWAP
15-minute	60-second TWAP
4-hour	60-second TWAP

5-minute markets started on a 30s window, then moved to 60s for markets deployed since August 14, 2026.

The README still documents the older 30s wording in places. Live production should treat 60s as the 5m target.

60 seconds is a lookback, not an update frequency.

State Variables That Matter

twap_open = 60s Chainlink TWAP at slot start
twap_now  = latest 60s Chainlink TWAP
t_left    = seconds remaining

Auxiliary only:

CEX mid for lead-lag (cexFeed.ts)
flow / book features
time-in-slot calibration

Not a primary target:

Binance last
Coinbase close guess
leftover 30s logic on new 5m markets

Signal Shape

Private layer:

[
P(up)t = f(\text{TWAP path vs } twap{open},\ \text{lead-lag},\ \text{flow},\ t_{left})
]

Rules:

Anchor to the official series first
Use CEX only as timing context
Treat a 52% read at t=20s as different from 52% at t=280s
Keep output calibrated as probability
Pin open and score live path on the same 60s window

The formula stays closed. The structure does not need to.

Code Map

Module	Job
`twapFeed.ts`	Chainlink TWAP via Polymarket RTDS
`signal.ts`	`P(up)` vs open reference
`cexFeed.ts`	auxiliary mid
`engine.ts`	consume probability and run the slot

Production feed:

RTDS 60s topic / windowSeconds: 60
exact filter {"symbol":"btc/usd"}
freshness on observation time
exact decimal / bigint math

Why the 30s → 60s Move Matters

Smoother series means:

spike features lose power
scratch thresholds shift
open-reference mismatch becomes a silent killer
any snapshot model is now research-only

This is why the public repo is framed as a TWAP60 prediction-trigger system. The trigger is not “price moved.” It is “the official average path now implies a tradeable probability.”

What Part 3 Covers

Once P(up) exists: staggered mid-band entries, 10–30s re-score, scratch vs redeem.

The BTC 5m Engine After TWAP60

ABROWNFOX001 — Mon, 31 Aug 2026 08:04:25 +0000

GitHub: https://github.com/abrownfox0/abrownfox001-twap60-prediction-trigger-system

This is an updated 4-part series on the live abrownfox001 system.

Part 1 — What the engine is now (this post)
Part 2 — TWAP60 signal stack
Part 3 — Slot lifecycle: enter, scratch, redeem
Part 4 — Public footprint, risks, private layer

The One-Line System

Forecast the official Chainlink TWAP path, buy it only near 50¢, and scratch weak tickets so only high-conviction legs reach resolution.

That is still the whole design. What changed in August 2026 is the official path itself: 5-minute crypto markets now settle on a 60-second Chainlink TWAP, not a last tick and not the earlier 30-second window.

The repo name already points at that world: abrownfox001-twap60-prediction-trigger-system.

Not a Convergence Bot

	Typical 94–99¢ farm	abrownfox001
Zone	Near-certainty	45–55¢ (~90% of fills)
Edge	Structure × size	TWAP-anchored 5m forecast
Exit	Hold almost everything	Scratch decay / redeem strength
Asset	Mixed	BTC 5m specialist

Public resolved sample from the README (150 markets near 50¢, Jul 2026):

Held-side win rate 60.7% (91W / 59L)
ROI on capital at resolution ≈ +24.5%
Average held entry ~0.50

Those numbers describe the filtered book, not every temporary fill.

The Three Layers That Have to Work Together

Private signal — P(up) from live TWAP vs slot-open reference
Fair entry — small clips in 45–55¢, median buy ~47s after open
Conviction cull — ~930 sampled markets bought and sold near the same price (0.504 → 0.503)

Miss any one layer and the 5m book becomes coin-flipping minus fees.

What You Can Run Today

Windows binary: Abrownfox001.exe (local setup, 2-day trial)
TypeScript source: npm start (dry-run by default)
Public modules: twapFeed.ts, signal.ts, engine.ts, clob.ts, markets.ts

The live calibrated trigger stays private. The repo is the architecture and execution shell.

What Part 2 Covers

How the signal must target 60s TWAP, why CEX last price is only lead-lag, and why open pinning from the same series is non-negotiable.

Polymarket TWAP60 vs Kalshi (4/4): Where Edge Survives After the Average

ABROWNFOX001 — Fri, 28 Aug 2026 06:49:49 +0000

GitHub: https://github.com/abrownfox0/abrownfox001-twap60-prediction-trigger-system

YouTube walkthrough: https://www.youtube.com/watch?v=XzhugRL6BV4

Parts 1–3 covered settlement, clocks, and the implementation fork.

This last post is the only question that matters after the plumbing works:

Where can a short-horizon BTC bot still have expectancy — and where is the 60-second average just a cleaner coin flip?

Live profile: @abrownfox001

1. What Died on Both Venues

Last-tick sniping is no longer a serious business.

A 3-second wick can still look dramatic on Binance.

It should not decide:

Polymarket’s Chainlink TWAP60 path
Kalshi’s final-minute CF Benchmarks average

If your edge was “own the print at the bell,” both platforms moved the target. That is the point of the design.

Also dead, or at least dying:

snapshot-close models
raw CEX-mid triggers with no official-series layer
one model reused across 5m and 15m labels
copy-trading a 99¢ wallet into a 50¢ book

2. What Can Still Work

Edge type	Best default home	Why
Live TWAP-path directional + scratch	Polymarket 5m	Official path exists during the slot; 288 trials/day
Late-window average reconstruction	Kalshi 15m	Close is concentrated in the final 60s of CF RTI
Mid-band fair-value execution	Both	Overpaying still kills any signal
Strict risk + stale-data refusal	Both	Process travels
Cross-venue “same BTC price” arb	Usually not	Different index, strike, clock, fees

The surviving edges are boring:

forecast the number the venue actually pays
buy it only when the price is fair
cut the trade when the thesis decays
do not confuse two official averages

3. Polymarket 5m: Where I Actually Run

This is the live abrownfox001 posture:

BTC only as core
5-minute clock
Chainlink TWAP60 as the state variable
entries in 45–55¢
10–30s re-score
scratch decaying tickets
redeem the filtered book

Public sample context from the project docs still frames the claim tightly:

held-side resolved book around 60.7%
that is the filtered book, not every scratch
mid-band fills dominate
the calibrated signal stays private

I stay here because the product matches the architecture:

official live path
enough independent slots
scratch-and-recycle can complete inside one market

That is a specialist choice, not a ranking of platforms.

4. Kalshi 15m: Where I Would Only Run a Fork

I would not point the 5m engine at KXBTC15M.

I would only run Kalshi after a separate engine exists:

CF index + explicit basis vs any proxy feed
contract strike pinned from Kalshi, not from “spot at t=0”
running reconstruction of the last-minute average
fewer mid-window trades
a late-slot confidence gate
paper results that reconcile to official expiration values

The honest Kalshi game is often:

The book is still quoting a live event, while the settlement average is becoming knowable.

That can be real. It is not the same as following a 5-minute TWAP path.

5. The Fee and Crowding Filter

Even a correct target can have no edge after costs.

On both venues, expectancy dies when:

you pay 53–55¢ for a 50¢ thought
scratch “breakeven” is actually 1–2¢ of spread
too many bots chase the same official average
your size moves the book more than your signal moves the probability

60-second settlement raised integrity.

It did not create free money.

A useful test:

EV after fees, after scratch costs, after missed fills
> 0
on official labels
over a regime that includes quiet days and trend days

If that is not true in paper, live size is just a faster way to learn the same fact.

6. What I Would Not Run

Polymarket 5m snapshot leftovers
Kalshi 15m with Polymarket 5m thresholds
cross-venue hedges that ignore index basis
hold-everything-to-resolution after a weak mid-slot read
“both venues say BTC” as a reason to share model weights
large size in the first seconds of a thin book

Those are not sophisticated. They are expensive ways to relabel noise.

7. A Simple Operating Policy

Production now

Polymarket BTC 5m TWAP60 engine
official series only
mid-band entries
active culling
hard risk caps

Research only

Kalshi 15m CF-close reconstruction
basis measurement between CEX, Chainlink TWAP, and CF RTI
separate labels, separate scratch config
no shared production brain

Never

trade if the official series is stale
mix open/strike families
scale size off a single good week

8. Series Recap

Both venues use a 60-second average. They do not use the same average.
5 minutes and 15 minutes are different jobs, not two skins of one ticker.
Crossing venues means forking feeds, labels, time features, and scratch logic.
Edge survives only where the bot forecasts the official number and refuses to overpay or overhold.

One sentence for the whole comparison:

Trade the index the venue names, on the clock the venue uses, at a price that still leaves room after fees.

Polymarket TWAP60 vs Kalshi (3/4): What a Directional Bot Must Change

ABROWNFOX001 — Fri, 28 Aug 2026 06:47:11 +0000

GitHub: https://github.com/abrownfox0/abrownfox001-twap60-prediction-trigger-system

YouTube walkthrough: https://www.youtube.com/watch?v=XzhugRL6BV4

Part 1: the venues settle on different official averages.

Part 2: 5 minutes and 15 minutes are different products.

Part 3 is the implementation fork. If you already have a Polymarket BTC 5m engine, this is the list of things that break when you point it at Kalshi.

Live profile: @abrownfox001

1. Do Not Ship One Brain With a Venue Flag

This is the failure mode:

if venue == "kalshi":
    symbol = "KXBTC15M"
else:
    symbol = "btc-updown-5m"
# same features, same thresholds, same scratch timer

That is not a dual-venue system. That is one calibrated clock wearing a costume.

Correct shape:

shared risk + logger
   ├─ Polymarket adapter → TWAP60 path engine (5m)
   └─ Kalshi adapter     → CF-close engine (15m)

Share process. Do not share the probability model.

2. Change the Primary Series First

Layer	Polymarket 5m	Kalshi 15m
Live official series	Chainlink 60s TWAP via RTDS	CF Benchmarks Real-Time Index
Decision question	Is the TWAP path beating open?	Will the final-minute CF average clear the strike?
Open / strike	Pin `twap_open` from the same TWAP feed	Read the contract strike / floor from Kalshi
Freshness field	TWAP observation timestamp	Index sample time vs close clock
Label for training	gamma resolution + TWAP60 path	Kalshi expiration value / official CF close

If this table is wrong, every downstream “optimization” is theater.

3. Rebuild Labels Before You Rebuild Features

A 5m model trained on Polymarket outcomes is labeled against Chainlink TWAP versus slot open.

A 15m model trained on Kalshi outcomes is labeled against a final-minute CF average versus strike.

Those label sets are not interchangeable.

Minimum migration work:

Collect official Kalshi settlement values, not Binance closes
Reconstruct the last 60 seconds of the CF index
Measure how often CEX last tick disagrees with that average
Only then fit P(up)
Shadow-trade before size

Do not fine-tune a Polymarket 5m checkpoint and call it a Kalshi bot.

4. Rewrite Time Features

5m constants that must not travel:

median entry near 47 seconds
re-score every 10–30 seconds as a universal law
late-slot behavior copied from a 300-second market
scratch after a 5m-sized “decay”

On Kalshi 15m, time has a different meaning:

first 8–10 minutes can be noise relative to a 60s close
the last 90 seconds are where reconstruction quality matters most
a 52% read at t=60s is not the same object as a 52% read at t=840s

Make seconds_to_close and fraction_of_close_window_elapsed venue-specific features. Do not reuse raw seconds_after_open weights.

5. Split the Trigger Logic

Polymarket 5m trigger

stream TWAP60
P = f(path vs twap_open, lead-lag, t_left)
if abs(P-0.5) >= edge and ask in 45–55¢:
    accumulate small clip

Kalshi 15m trigger

track CF index + basis vs your proxy
as close approaches, reconstruct running 60s average
P = f(reconstructed_avg vs strike, remaining uncertainty)
if EV clears fees + confidence gate:
    trade

The first is path-following.

The second becomes late-window estimation.

Keep both honest about which one they are.

6. Retune Scratch, Don’t Copy It

Scratch is still useful on both venues. The schedule is not.

On Polymarket 5m:

books are often tradeable near 50¢
a decaying 20-second-old thesis can be flattened quickly
capital can be reused in the next slot

On Kalshi 15m:

exiting too early can dump a ticket before the close average even exists
exiting too late can mean paying the full official miss
depth and fees around the strike change the meaning of “breakeven”

Re-estimate:

minimum hold time
probability drop required to flatten
max adverse move
last-N-seconds “no new entries / no panic scratch” policy

7. Execution and Ops Fork

These are not strategy details. They still break bots.

Ops item	Polymarket	Kalshi
Auth	wallet / CLOB v2 signing	KYC account + exchange API
Position record	on-chain outcome tokens	centralized account ledger
Rate limits	volume-tiered CLOB buckets	exchange API limits
Reconciliation	chain + data API	fill + settlement reports
Identity / geo	wallet-native internationally	full onboarding first
Failure mode	stale RTDS + wrong TWAP window	wrong strike + proxy basis drift

A working 5m Windows binary does not become a Kalshi engine because you added an API key field.

8. Shared Layers That Should Travel

Keep these common:

daily loss cap
per-slot exposure cap
kill switch
structured logs
refuse stale data
no trade if official series is missing
paper harness before live size

That is the risk brain. It can supervise two adapters.

9. Migration Checklist

[ ] Separate model files per venue
[ ] Separate open/strike pinning code
[ ] Separate label pipeline
[ ] Separate scratch config
[ ] Shadow 200+ Kalshi slots before capital
[ ] Compare CEX-last vs official close disagreement rate
[ ] Log venue, index, window, strike_or_open, resolution_src on every decision
[ ] Keep Polymarket 5m production untouched while Kalshi stays in paper

If you cannot diff a Polymarket decision log from a Kalshi decision log in one glance, the fork is incomplete.

10. What Part 4 Will Cover

After the fork exists, the only remaining question is economic:

where a mid-band directional read still has room
where last-minute reconstruction is the real game
where fees, basis, and crowding erase both
what I would actually run, and what I would not

Polymarket TWAP60 vs Kalshi (2/4): 5-Minute Clock vs 15-Minute Clock

ABROWNFOX001 — Fri, 28 Aug 2026 06:46:25 +0000

GitHub: https://github.com/abrownfox0/abrownfox001-twap60-prediction-trigger-system

YouTube walkthrough: https://www.youtube.com/watch?v=XzhugRL6BV4

Part 1 said the first split is settlement design:

Polymarket crypto Up/Down → Chainlink TWAP60
Kalshi short BTC → 60-second CF Benchmarks Real-Time Index average

Part 2 is about the clock those rules sit inside.

A 5-minute market and a 15-minute market are not the same product with a different timer. They create different bots.

Live profile: @abrownfox001

1. The Product Split

	Polymarket BTC Up/Down	Kalshi BTC short-horizon
Flagship short contract	5-minute	15-minute (`KXBTC15M`)
Slots per day	288	96
Official close	Chainlink TWAP path	Final-minute CF average vs strike
Typical book	Coin-flip band near 50¢	Up/Down pair around a defined threshold
Venue type	On-chain CLOB	CFTC-regulated exchange
Native 5-minute BTC up/down	Yes	No equivalent flagship product

Polymarket built its crypto franchise on the 5-minute clock.

Kalshi’s shortest major BTC up/down is a quarter-hour.

That one design choice changes signal horizon, scratch cadence, capital turnover, and how much a last-minute average can dominate the outcome.

2. Why 5 Minutes Is a Different Job

On a 5-minute slot:

There is almost no time to “wait for the story”
Fair value spends most of the slot near 50¢
A delayed fill is a thesis change, not a minor slippage
Scratching a weak ticket at 90 seconds can be the whole strategy
You get another market in 5 minutes, so recycling capital matters

That is why abrownfox001 is a specialist loop:

stream TWAP60
pin open reference
enter only in 45–55¢
re-score every 10–30s
scratch decay / redeem strength

The clock forces specialization. Breadth is optional. Cadence is not.

3. Why 15 Minutes Is Also a Different Job

On Kalshi’s 15-minute BTC contract:

The market has three times as long to reprice
The economically decisive print is often the final 60 seconds of the CF index
Mid-slot CEX noise can look violent and still not decide settlement
Strike / floor convention matters as much as “direction”
You get fewer independent slots per day

A bot that sprays 5-minute timing constants onto a 15-minute book will:

overtrade the first 10 minutes
treat noise as signal
scratch too early
or hold through a last-minute average it never modeled

Same instinct (“will BTC finish up?”). Different state variable.

4. How Much of the Contract Is the Average?

This ratio is underrated.

Contract	Length	Official average window	Window as % of life
Polymarket 5m	300s	60s TWAP	20%
Kalshi 15m	900s	final 60s CF average	~7%

On Polymarket 5m, the averaging window is a large fraction of the whole game.

On Kalshi 15m, the average is a closing ritual after a longer live market.

That is why:

Polymarket 5m rewards path-following the live TWAP
Kalshi 15m rewards late reconstruction of the CF close more than constant 5m twitching

5. Liquidity and Book Shape Follow the Clock

Polymarket 5m

Dense stream of fresh 50¢ books
Small clips can source size if you wait ~30–60s instead of lifting t=0
Sell-side volume often means scratches, not a different strategy
High slot count makes a specialist engine viable

Kalshi 15m

Fewer auctions per day, more time per auction
Liquidity can concentrate around the defined up/down pair
Overnight and weekend books can thin even though crypto trades 24/7
Identity-verified flow changes who is on the other side of the clip

Do not assume a 50¢ Polymarket fill model transfers to Kalshi just because both screens say “BTC Up.”

6. Open Reference vs Strike

Polymarket 5m is conceptually clean:

Up wins if end TWAP >= open TWAP

Kalshi 15m is contract-defined:

Up/Yes wins if final-minute CF average clears the strike / threshold

If you pin “open” from Binance mid on either venue, you invent a third market that nobody settles.

The 5-minute engine lives or dies on same-series open pinning.

The 15-minute engine lives or dies on correct strike + correct close index.

7. Operational Consequences

Design choice	5m Polymarket	15m Kalshi
Re-score cadence	10–30s	can be slower mid-window, faster in last 90s
Median useful entry	often after the first thin seconds	often later, closer to when the close becomes estimable
Scratch importance	extremely high	still high, different threshold schedule
Capital turnover	very high	lower
Model reuse	do not reuse 15m weights	do not reuse 5m weights
Infra bottleneck	feed freshness + CLOB latency	index reconstruction + exchange API / account rules

One codebase with a venue flag is fine.

One calibrated brain for both clocks is not.

8. Why I Stay on the 5-Minute Clock

The public abrownfox001 system is built around Polymarket BTC 5m because that product matches the architecture:

official path available during the slot
enough independent trials per day
mid-band liquidity for small clips
scratch-and-recycle loop that can complete inside one market

Kalshi is the right lab for a 15-minute CF-close engine.

It is the wrong place to paste a 5-minute TWAP trigger and hope the word “bitcoin” does the rest.

9. What Part 3 Will Cover

Once the clocks are distinct, the implementation split becomes concrete:

which modules can be shared
which thresholds cannot
how a directional bot should change feeds, labels, and scratch logic when it crosses from Polymarket TWAP60 to Kalshi CF-60s

Polymarket TWAP60 vs Kalshi: Why Settlement Design Decides Your Bot (Series 1/4)

ABROWNFOX001 — Fri, 28 Aug 2026 06:44:41 +0000

GitHub: https://github.com/abrownfox0/abrownfox001-twap60-prediction-trigger-system

YouTube walkthrough: https://www.youtube.com/watch?v=XzhugRL6BV4

This is a new 4-part series comparing the two venues that actually matter for short-horizon BTC direction:

Part 1 — Settlement design: Polymarket TWAP60 vs Kalshi 60s average (this post)
Part 2 — Product shape: 5-minute specialist vs 15-minute regulated stack
Part 3 — What a directional bot must change when crossing venues
Part 4 — Where edge survives, and where it dies

Live profile: @abrownfox001

The Real Split Is Not “On-Chain vs Regulated”

People compare Polymarket and Kalshi as if the important difference is KYC, geography, or chain vs centralized matching.

For a short-horizon BTC bot, those matter later.

The first difference is simpler:

What exact number decides Up vs Down?

If you get that wrong, every signal, backtest, and scratch rule is solving the wrong problem.

Two Venues, Two Official Averages

Both platforms moved away from “whatever the last print was.”

Both now settle short BTC contracts on a one-minute average.

They do not use the same average.

	Polymarket crypto Up/Down	Kalshi BTC short contracts
Shortest liquid product	5-minute Up/Down	15-minute Up/Down (`KXBTC15M`)
Settlement idea	Time-weighted average	60-second simple average
Official source	Chainlink TWAP	CF Benchmarks Real-Time Index (BRTI family)
Window	60 seconds for current 5m / 15m / 4h crypto	Final 60 seconds before close, sampled ~1s
Open reference	Matching TWAP at slot start	Strike / floor set by the contract
Feed path for bots	Polymarket RTDS or Chainlink Data Streams	Kalshi market fields + CF Benchmarks index
Market structure	On-chain CLOB	Centralized CFTC-regulated exchange

Same word — “60-second average.”

Different index. Different sampling. Different product clock.

Why Both Platforms Converged on 60 Seconds

Snapshot settlement created the same failure mode everywhere:

A brief push into one venue’s book
A wick at the exact close
Retail on the wrong side of a coin-flip ticket

Polymarket’s 5-minute books made that problem famous. Research around those markets documented large settlement-window gains for a small set of wallets. The platform response was explicit: replace the snapshot with Chainlink TWAP.

Kalshi never made the 5-minute product the flagship. Its shortest BTC up/down is 15 minutes, and crypto settlement is already defined as a 60-second average of the CF Benchmarks real-time index. Same defensive idea: force any attacker to hold the print for a full minute, not a few seconds.

The industry conclusion is now obvious:

Short crypto binaries cannot be trusted if one tick can decide the payout.

The Trap: “60 Seconds” Does Not Mean “Same Target”

This is the part most copy-paste bots miss.

Polymarket TWAP60

Chainlink-computed lookback average
Live path can be streamed throughout the slot
Open and close both belong to the same TWAP family
Best mental model: where is the official average path heading versus open?

Kalshi 60s average

Simple average of the CF Benchmarks real-time index over the final minute
Multi-exchange institutional index, not “Binance last”
Strike is set by the contract, not necessarily “your local TWAP at t=0”
Best mental model: will the final-minute CF average finish above the strike?

If you train on Polymarket TWAP and fire the same trigger on Kalshi, you are transferring a correlation, not a settlement identity.

Why I Still Specialize on Polymarket BTC 5m

The abrownfox001 engine is a 5-minute specialist.

That choice is not ideology. It is product shape:

288 BTC 5m slots per day
Coin-flip books near 50¢
Official live TWAP path available during the slot
Fast enough that scratch logic can recycle capital
Slow enough, after TWAP60, that last-tick sniping is no longer the main game

Kalshi’s 15-minute BTC contract is a cousin, not a clone:

Longer horizon
Different index
Different liquidity and fee regime
Different open/strike convention
No native 5-minute equivalent in the same way

A 15-minute model can be useful. It is not a drop-in replacement for a 5-minute TWAP path follower.

The Bot Question This Series Is Built Around

Do not start with “which platform is better?”

Start with this:

What series does the venue actually pay?
Can I stream that series live, not just reconstruct it after the fact?
Is the open reference from the same family as the close?
Is the product 5 minutes or 15 minutes?
After fees and scratch costs, is there still room for a mid-band directional read?

Polymarket TWAP60 answers those questions one way.

Kalshi’s CF 60-second close answers them another way.

Same trader instinct. Different state machine.

What Part 2 Will Cover

Product design:

Why Polymarket’s 5-minute clock creates a different bot than Kalshi’s 15-minute clock
Where liquidity actually sits
Why mid-band 50¢ trading and 15-minute strike trading are not the same job
