Part 2 was matching-engine p99.
Part 3 is the quieter half of speed: knowing the fill is real.
A fast match that takes 20 seconds to show in positions is still a slow exchange. That lag is one reason offshore flow thinned while the US book kept climbing.
What already shipped
Before the Q4 Rust CLOB lands, two data-path upgrades are already live:
-
In-house indexer (
rindexer, Rust): on-chain events visible up to ~14 blocks / ~28 seconds sooner; index within ~0–10ms of block broadcast - Data API v2 (Rust): about 50% faster p50, 90% faster p99, backed by internal index tables
- UI now reads those tables for trades, positions, and balances
The CLOB rewrite is still the bottleneck for place/cancel. This layer is the bottleneck for trust.
Why bots feel “UI vs chain” drift
@abrownfox001 lives on a 300-second clock.
After a clip or a scratch the engine must know, immediately:
- did the order fill?
- what size remains?
- can I send the next clip?
- is this slot already flat?
If the user channel says filled and Data API still shows the old position, you get the two classic bugs:
- double-send — retry because the position lookback is stale
- phantom inventory — try to scratch shares you already sold
Neither is a signal error. Both are indexer lag wearing a strategy costume.
What faster data changes
| Old pain | After Rust data path |
|---|---|
| Activity tab trails the wallet | Positions/balances load on v2 tables |
| Fill truth waits on a slow third-party index | In-house index near block time |
| p99 API spikes during bursts | v2 tails cut hard |
| Halt rules fire on “unknown inventory” | fewer false unknowns |
Retail users feel the same thing as “the app is lying.”
Bots feel it as a broken intent_id.
What I will not do with this
Faster reads are not permission to add features.
Until the matching engine itself is on Rust, I still:
- treat TWAP freshness as a halt
- cap clips in the 45–55¢ band
- refuse a second order until the first intent is reconciled
- prefer websocket fills over REST hammering
Data API v2 makes reconciliation cheaper. It does not make a stale book safe.
The test that matters
When a BTC 5m scratch prints, I want:
fill ack
local inventory = 0
v2 position = 0
activity tab agrees
If those four disagree for more than a couple of seconds, the offshore book still feels late — no matter how good the Rust CLOB benchmarks look on a slide.
Part 4: what a bot should freeze during Q4 rails season.
Not financial advice. Paper or micro-size first.
