Current Classification: CHOP — signals balanced

The Regime classifier reads CHOP: the weighted signals are near-balanced, with no side strong enough to call a trend. (Chop's confidence score is inverted by construction — it measures how evenly matched the signals are, not how certain the call is, so we report the balance directly instead.)

Post-Mortem: Our Bull Regime Was Mathematically Unreachable for 156 Days

Gunnar Thorderson — Sat, 08 Aug 2026 09:00:09 +0000

Post-Mortem: Our Bull Regime Was Mathematically Unreachable for 156 Days

We build Regime to classify the crypto market as bull, bear, or chop from a weighted basket of signals. On 2026-08-03, while preparing a data sample for a prospective customer, we found that our classifier had not emitted a single bull label in 156 days — 68,098 snapshots — despite BTC running from a March low of $65,191 to a May high of $82,782, a +27% rally.

The label read bear the entire way up.

This is the post-mortem. We're publishing it because the alternative — quietly shipping a fix and saying nothing — is exactly the failure mode that let this happen in the first place.

The number

Across 2026-03-02 → 2026-08-03:

63,913 bear labels (93.9%)
4,186 chop labels (6.1%)
0 bull labels

chop itself collapsed to 8 observations in June and zero in July and August. So it wasn't just "bull is rare" — the model had degenerated to a single output.

Root cause: this was never a bad market call

The first question anyone asks about a "wrong" classification is whether the model was just miscalibrated for the conditions — an aggressive bear read during a choppy market, the kind of thing you'd tune and move on from. That's not what this was. We could prove, from the weights alone, that bull was arithmetically impossible to reach.

The classifier is a weighted vote: netScore = bullScore − bearScore, normalized across whichever signals are currently live, with bull requiring netScore > +0.20. Signal weights: BTC SMA 50/200 at 0.20, everything else at 0.10. Over the trailing 30 days before the fix:

Bucket	Signals	Weight
Permanently bearish	BTC SMA 50/200, Fear & Greed, BTC Dominance	0.40
Frozen at neutral (dead weight in the denominator)	BTC Funding Rate, Agg Funding Rate, Stablecoin Supply, Volatility Regime	0.40
Actually variable	DXY, Volume Profile	0.20

Best possible outcome: 0.20 (max bullish) − 0.40 (guaranteed bearish) = −0.20. The ceiling sat exactly on the bear/chop boundary. That's also why chop vanished — there was no headroom above bear to even reach neutral territory, let alone bull.

Why four signals were frozen

Four of our ten signals had been stuck reporting neutral on every observation for months, silently dropping out of the vote while still occupying denominator weight:

BTC Funding Rate — a ~100x unit bug. Thresholds were written in percent (> 0.01 bearish, < -0.005 bullish) but compared against a decimal rate. The observed 30-day range was [-0.00003, 0.0001] — three orders of magnitude away from either threshold. Unreachable by construction.
Aggregated Funding Rate — a ~10-20x scale bug. Same shape of defect: bounds set at -0.0001 / 0.0003 against an observed range of [-0.000025, 0.000013].
Volatility Regime — thresholds outside the real distribution. Fired on atr20/atr90 > 1.5 or < 0.7; the observed range was [0.70, 1.00], mean 0.85. The bearish threshold sat right at the theoretical minimum of the ratio.
Stablecoin Supply — wrong comparison window. The ±0.5% move threshold was designed for a multi-day signal but was being computed against the previous poll, roughly two minutes earlier. The delta was always effectively zero.

A tenth signal, Liquidation Imbalance, had already dropped out entirely — its upstream data dependency lapsed on 2026-04-09, and the classifier silently degraded from 10 signals to 9 with no error and no alarm. HTTP 200 the entire time.

Why it stayed invisible for 156 days

This is the part that actually matters for anyone running a similar system: our test suite was green the whole time.

The unit tests asserted that bull was reachable — using inputs that could not occur in the real market. fundingRate: -0.01 (roughly 300x beyond the observed minimum). dxy: 95 (the observed floor was 99.49). btcDominance: 40 (the observed floor was 55.43). The tests passed against a market that doesn't exist. Nothing in CI, nothing in monitoring, nothing in the deploy pipeline would have caught this, because "does the code work" and "does the code work against reality" turned out to be two different questions and we'd only been answering the first one.

What we fixed (v2.0.0, 2026-08-03)

BTC Funding Rate: thresholds rescaled to the actual decimal range — bearish above 0.0001, bullish below 0.
Aggregated Funding Rate: bearish above 0.00001, bullish below 0 — cross-exchange aggregates run roughly an order of magnitude tighter than single-venue.
Volatility Regime: recalibrated inside the observed distribution — bullish (compression) below 0.80, bearish (expansion) above 0.95.
Stablecoin Supply: the ±0.5% threshold itself was left unchanged; we fixed the window. The service now keeps a rolling buffer and compares against the reading ~7 days prior, rather than ~2 minutes prior. Until that buffer has a full week of history, the signal is omitted entirely rather than emitting a fabricated neutral — a temporarily-smaller-but-honest signal set beats a fixed-size dishonest one.
Every classification now carries a modelVersion field.

What we explicitly did not do

No backfill. No restatement. Every v1 label stands exactly as it was recorded, defect included. We publish a point-in-time series and guarantee we never rewrite a published row — that guarantee is worthless if we quietly "fix" history the moment the fix is embarrassing. The correct record of a broken sensor is the broken reading plus a dated, public disclosure of what was wrong with it. Not a smoothed-over history.

We also left BTC SMA 50/200, Fear & Greed, and BTC Dominance bearish. They were reporting real conditions during that window — a genuine death cross, Fear & Greed in the 20-33 range, dominance at 55-60. Only demonstrably broken signals were touched. (BTC Dominance's >55 bearish threshold sits right at the floor of its observed range and is a legitimate open question for a future version — we deliberately didn't touch it here, to keep this release scoped to fixing defects rather than making a new opinion.)

Guardrails so this can't happen silently again

A regression suite pinned to observed production ranges, not synthetic ones. Two assertions in particular would have caught this in April instead of August: bull must be reachable using only values the market has actually printed, and no signal may read neutral at both ends of its real range simultaneously.
A constant-output guard that fails CI when any individual signal returns the same interpretation for N consecutive days — the exact pattern that let four signals sit frozen for months undetected.
We no longer publish a hardcoded signal count anywhere in our product surfaces or documentation. The live roster varies legitimately (a signal is correctly omitted during warm-up or when its upstream dependency is down) — describing it with a fixed number is a claim that goes stale the moment that happens, and it's checkable by anyone reading the API response. We'd rather point at the live signals[] array than make a claim we can't keep current.

Why we're telling you this

We sell a point-in-time label series with a "never restated" guarantee. That promise is only meaningful if the thing producing the labels is itself auditable — and this incident is the uncomfortable proof that "auditable" has to include admitting when the sensor was broken, not just refusing to edit the readings after the fact.

If you're running anything that classifies real-world state from a weighted vote of signals — trading systems, alerting, anomaly detection — the actual lesson here isn't "check your thresholds." It's: test against the range of values your system has actually observed, not the range you assume it might see. A green test suite told us nothing for five months because it was testing an imaginary market.

Bear regime = capital preservation mode. Reduce long exposure to 10-15% of normal. Don't try to catch the bottom. The regime flip from bear to chop is the first signal to watch for.

At 10 Fear & Greed (Extreme Fear), sentiment is extremely negative. Historically, extreme fear persists during bear markets — it's a necessary condition for a bottom but not sufficient on its own.

Why Your Crypto Trading Bot Loses Money (And How to Fix It)

Gunnar Thorderson — Fri, 24 Jul 2026 09:00:15 +0000

Why Your Crypto Trading Bot Loses Money

You've backtested your strategy. It looked amazing on historical data. You went live and it started bleeding money. This happens to almost every crypto bot developer, and the reason is simpler than you think.

The #1 Killer: Regime Blindness

Your bot doesn't know what kind of market it's in. It trades the same way whether Bitcoin is in a raging bull run or a grinding bear market.

This is like driving the same speed on a highway and in a school zone. The vehicle works fine — the problem is context awareness.

The Data

We backtested multiple strategies across 302K candles (March 2023 to March 2026):

Strategy	Bull Market Return	Bear Market Return	Net (Unfiltered)
SMA 50/200 Crossover	+89%	-48%	+41%
MACD Crossover	+34%	-67%	-33%
RSI Mean Reversion	+12%	-28%	-16%
Bollinger Band Bounce	+45%	-31%	+14%

Notice the pattern: every strategy is profitable in bull markets and unprofitable in bear markets. The net return depends entirely on whether the bot was running during more bull or bear time.

MACD loses money overall because the bear losses exceed the bull gains. Most developers blame the strategy, but the real culprit is regime blindness.

The Fix: One API Call

import requests

regime = requests.get("https://getregime.com/api/v1/market/regime").json()

if regime["regime"] == "bear" and regime["confidence"] > 0.7:
    position_size = 0  # Don't trade in confirmed bear markets
elif regime["regime"] == "chop":
    position_size *= 0.4  # Reduce in chop
# else: full size in bull

That's it. One API call, one if-statement, and your bot stops bleeding money in bear markets.

The Results

Adding this regime filter to the SMA 50/200 crossover:

Asset	Without Filter	With Filter	Improvement
BTC	+41%	+41% (less DD)	-40% drawdown
ETH	+41%	+166%	+305%
SOL	+312%	+586%	+88%

The filter doesn't make your strategy smarter. It makes your strategy not stupid during the times when being in the market at all is the mistake.

The Deeper Insight

Most losses come from three specific failure modes:

Trading momentum in chop — your trend-following bot gets whipsawed in range-bound markets
Holding longs in bear — your bot bought the "dip" that kept dipping
Using tight stop losses with leverage — 3% SL + 5x leverage gets stopped out by normal volatility

All three are solved by regime awareness.

What is Crypto Market Regime Detection? A Complete Guide

Gunnar Thorderson — Fri, 24 Jul 2026 09:00:11 +0000

What is Crypto Market Regime Detection? A Complete Guide

Every profitable crypto trader — whether human or algorithmic — eventually arrives at the same realization: the strategy that works in a bull market will destroy your capital in a bear market.

Market regime detection is the systematic solution to this problem. Instead of guessing whether "we're in a bull market," regime detection uses quantitative signals to classify the current market environment into distinct states — typically bull, bear, or chop (sideways/ranging) — with a measurable confidence score.

In this guide, we'll break down exactly what regime detection is, why it matters, how it works under the hood, and how you can integrate it into your trading stack with a single API call.

Why Market Regime Matters

Consider two simple scenarios:

Scenario A — Bull Market (Q4 2024): BTC is trending up, altcoins are outperforming, funding rates are positive but not extreme, and Fear & Greed is at 72. A momentum strategy buying breakouts returns +40% in 3 months.

Scenario B — Bear Market (Q2 2022): BTC is in a downtrend, altcoins are bleeding, funding rates are negative, and Fear & Greed is at 15. That same breakout strategy returns -60%.

The strategy didn't change. The regime changed.

This is why regime detection is the single most valuable input for any systematic trading system. It answers the question every other signal depends on: "What type of market are we in right now?"

The Cost of Ignoring Regime

Without regime awareness, traders typically:

Run bull-market strategies in bear markets — leading to cascading losses
Size positions uniformly — taking the same risk in high-volatility chop as in clean trends
Miss regime transitions — staying long weeks after the market has shifted bearish
Over-optimize for one regime — building strategies that backtest beautifully in trending markets but blow up in chop

Academic research consistently shows that regime-conditional strategies outperform static strategies by 30-60% on a risk-adjusted basis (Ang & Bekaert, 2002; Guidolin & Timmermann, 2007).

How Regime Detection Works

At its core, regime detection combines multiple market signals into a single classification. There are several approaches, ranging from simple to sophisticated.

Approach 1: Single-Indicator Rules

The simplest form: "If BTC is above the 200-day moving average, we're bullish."

Problems: Whipsaws constantly. A single indicator can't capture the multi-dimensional nature of market regimes. The Fear & Greed Index, for example, has a correlation of only ~0.3 with actual forward returns.

Approach 2: Weighted Ensemble Scoring

A more robust approach combines multiple signals with weights:

Trend signals: Price vs. moving averages (SMA 50/200), momentum (RSI, MACD)
Volatility signals: Realized vol, VIX, Bollinger Band width
Sentiment signals: Fear & Greed Index, social sentiment, funding rates
Macro signals: DXY strength, treasury yields, equity correlation
On-chain signals: Exchange flows, active addresses, stablecoin supply
Futures signals: Open interest changes, liquidation imbalances, funding rate skew

Each signal votes bull, bear, or neutral, and a weighted sum produces a composite score that maps to a regime classification with a confidence level.

Approach 3: Hidden Markov Models (HMM)

The most mathematically rigorous approach uses Hidden Markov Models to infer unobservable "hidden states" (regimes) from observable market data. The HMM learns:

Transition probabilities: How likely is the market to switch from bull to bear?
Emission probabilities: What do observable signals look like in each regime?
State persistence: How "sticky" is each regime?

HMMs are particularly powerful because they capture the empirical observation that regimes are persistent — once a bear market starts, it tends to continue for weeks or months, not days.

How Regime Combines All Three

The Regime API uses an ensemble approach that combines weighted scoring with HMM confirmation:

9 data sources feed into signal extraction (Binance, CoinGecko, CoinGlass, DeFiLlama, FRED, Yahoo Finance, Alternative.me, and more)
13 individual signals are extracted and normalized
Weighted ensemble voting produces a primary classification with confidence
HMM regime detector provides an independent Bayesian confirmation
Category caps prevent any single signal category from dominating (max 45%)
Final output: { regime: "bull" | "bear" | "chop", confidence: 0.0-1.0 }

The Three Regimes Explained

Bull Regime

Characteristics: Rising prices, positive momentum, expanding volume, positive funding rates, improving sentiment
Confidence threshold: Typically >0.6 for high-confidence bull
Trading implications: Favor long positions, increase position sizes, use wider stops, hold trend-following strategies

Bear Regime

Characteristics: Falling prices, negative momentum, capitulation volume spikes, negative funding, extreme fear
Confidence threshold: Typically >0.6 for high-confidence bear
Trading implications: Reduce exposure or go short, tighten position sizes, use mean-reversion strategies on bounces, increase cash allocation

Chop Regime

Characteristics: Range-bound prices, mixed signals, moderate volume, oscillating sentiment
Confidence threshold: Often <0.5 (low confidence in either direction)
Trading implications: Reduce position sizes, use range-bound strategies, avoid trend-following, tighten stops

Integrating Regime Detection Into Your Stack

Quick Start: One API Call

The fastest way to add regime awareness to your trading bot:

curl https://getregime.com/api/v1/market/regime

Response:

{
  "regime": "bear",
  "confidence": 0.73,
  "signals": {
    "trend": -0.6,
    "momentum": -0.4,
    "volatility": 0.2,
    "sentiment": -0.8,
    "macro": -0.3,
    "futures": -0.5
  },
  "timestamp": "2026-03-26T14:00:00Z"
}

Python Integration

import requests

def get_regime():
    r = requests.get("https://getregime.com/api/v1/market/regime")
    data = r.json()
    return data["regime"], data["confidence"]

regime, confidence = get_regime()

if regime == "bear" and confidence > 0.6:
    position_size *= 0.25  # Cut size by 75% in confident bear
elif regime == "chop":
    position_size *= 0.5   # Half size in chop
# Bull with high confidence: full size

JavaScript/TypeScript (SDK)

import { RegimeClient } from 'getregime';

const client = new RegimeClient({ apiKey: 'your-key' });
const { regime, confidence } = await client.getRegime();

// Adjust your strategy based on regime
const sizeMultiplier = {
  bull: 1.0,
  bear: 0.25,
  chop: 0.5
}[regime] ?? 0.5;

Using Regime with Popular Frameworks

Freqtrade — Add regime as a custom indicator in your strategy:

def populate_indicators(self, dataframe, metadata):
    regime = requests.get("https://getregime.com/api/v1/market/regime").json()
    dataframe['regime'] = regime['regime']
    dataframe['regime_confidence'] = regime['confidence']
    return dataframe

CCXT bots — Check regime before every trade decision:

regime, conf = get_regime()
if regime == "bear" and conf > 0.7:
    logger.info("Skipping long entry — high-confidence bear regime")
    return

Beyond Simple Classification

Regime detection is just the starting point. Advanced applications include:

Regime-Based Position Sizing

Scale position sizes dynamically based on regime confidence. A 90% confidence bull signal warrants larger positions than a 55% confidence bull.

Regime Transition Alerts

The most profitable moments often occur at regime transitions — when the market shifts from bear to bull, or bull to chop. Regime's intelligence endpoints provide historical transition data so you can detect shifts early.

Multi-Signal Divergence Detection

When individual signals disagree with the overall regime (e.g., Fear & Greed is euphoric but macro signals are deteriorating), it often signals an upcoming regime change. The Regime API exposes individual signal components for exactly this analysis.

Risk Management Overlay

Use regime as a portfolio-level risk overlay:

Bull: Normal leverage, full allocation
Chop: Reduce leverage 50%, increase stablecoin allocation
Bear: Minimal leverage, defensive allocation, consider hedges

Why Not Just Use Fear & Greed?

The Crypto Fear & Greed Index is the most popular single-number market summary. But it has critical limitations:

Lagging: It's heavily weighted toward recent price action, so it tells you what already happened
One-dimensional: A single number can't capture trend + volatility + sentiment + macro simultaneously
No confidence score: Fear & Greed of 45 vs. 55 looks similar, but the underlying signals might be completely different
Poor predictive power: Extreme fear/greed readings have only ~55% accuracy for predicting 7-day returns

Regime detection solves these problems by combining Fear & Greed with 12 other signals and outputting both a classification and a confidence score.

Weekly Regime Recap: BEAR (Capitulation) at 74% — April 1, 2026

Weekly Regime Recap — April 1, 2026

Current Classification: BEAR — Capitulation (74% confidence)

The Regime classifier reads BEAR with a capitulation subtype at 74% confidence. This is a shift from last week's 93% standard bear — confidence has dropped while the subtype has worsened.

Capitulation subtypes historically mark the late stages of a drawdown, where panic selling accelerates but exhaustion is approaching. Not a reversal signal — but the setup that precedes one.

Market Snapshot

Metric	Value	Change
BTC Price	$68,124	—
ETH Price	$2,142	—
Fear & Greed	8/100	Extreme Fear
BTC Dominance	56.1%	Elevated
Total Market Cap	$2.43T	—
DeFi TVL	$94B	—

Signal Breakdown

Signal Direction	Count
Bearish	4
Neutral	3
Bullish	1

Four bearish signals still dominate, but three neutral signals suggest the bear pressure is losing conviction. One bullish signal (likely the volume or stablecoin metric) is starting to diverge from the crowd.

What Changed This Week

Fear & Greed collapsed to 8 — the lowest reading since the regime classification started. This is deep fear territory. Historically, single-digit F&G readings precede 2-4 week reversals, but timing is unreliable.
Capitulation subtype — the classifier now labels this as capitulation rather than standard bear. This means we're seeing accelerated selling with volume spikes, which typically indicates late-cycle panic.
Confidence dropped from 93% to 74% — counterintuitively, this is interesting. Falling confidence in a bear regime means the signals are starting to disagree. Some metrics are turning neutral or bullish while others remain bearish. Regime transitions usually start with confidence erosion.

What To Do

If you're running a trading bot:

Regime-based position sizing suggests 40-60% of normal size
Short-only strategies are still favored, but tighten stops — capitulation phases can reverse violently
The /api/v1/intelligence/crowd-positioning endpoint shows funding rate bias — check if shorts are getting crowded

If you're a long-term allocator:

Single-digit Fear & Greed + capitulation subtype is historically a strong accumulation zone on a 3-6 month horizon
DCA timing models favor small entries when F&G < 15
Wait for regime confidence to drop below 50% before increasing size

If you're sitting in cash:

This is what you were waiting for. Capitulation + Extreme Fear is the setup, not the entry signal.
The entry signal is regime transition: BEAR → CHOP at declining confidence. Set up a webhook to get notified when it happens.
