Market Regime Detection: Quiet, Normal, or Chaos?
Not every strategy works in every market condition. Learn how QSA's regime detector classifies the market and why it's the first gate in the signal pipeline.
The Regime Problem
Here's a fact that most retail traders ignore: strategies that crush it in trending markets get destroyed in ranging markets, and vice versa. A momentum breakout strategy in a choppy market will get stopped out repeatedly. A mean reversion strategy in a strong trend will fade every move and lose.
The problem isn't the strategy — it's using the wrong strategy for the current market condition. That's what regime detection solves.
QSA's Three Market Regimes
QSA classifies the market into three regimes based on realized volatility, ATR expansion/contraction, and directional movement:
QUIET: Volatility is compressed. ATR is below its 20-period average. Price is moving in tight ranges. This is the calm before the storm — breakout scanners fire with highest conviction here because compression precedes expansion.
NORMAL: Standard market conditions. Trends develop, pullbacks occur, patterns form. Most strategies work well here. This is the most common regime (~60% of the time).
CHAOS: Volatility is extremely elevated. ATR is 2x+ its average. Price moves are erratic and unpredictable. Stop losses get hit frequently. Only mean reversion works reliably here — fade the extremes and take quick profits.
How Regime Affects Conviction Scores
Regime is a multiplier in the conviction engine, not just a filter. Here's how it works:
In QUIET regime: • Breakout/momentum signals get a +8 point regime bonus • Mean reversion signals get a -2 penalty (ranges don't mean-revert when they're about to break)
In NORMAL regime: • All strategies get a moderate +5 bonus if aligned with the trend • Misaligned strategies get a -2 penalty
In CHAOS regime: • Mean reversion signals get a +8 bonus (extremes snap back) • Momentum/breakout signals get a -5 penalty (breakouts fail in chaos)
This means the same scanner signal can be an S-grade setup in one regime and a B-grade in another. Context is everything.
Trading Each Regime
QUIET regime strategy: • Watch compression scanners (Momentum Ignition, Breakout) • Reduce position size on mean reversion • Be ready for expansion — set alerts on key levels • This regime often precedes the biggest moves
NORMAL regime strategy: • Full scanner suite is active • Confluence scoring works best here • Follow the trend, trade pullbacks • Standard position sizing
CHAOS regime strategy: • Focus on mean reversion scanners (VWAP Deviation, RSI Extremes) • Reduce position sizes by 50% • Take profits quickly — chaos doesn't trend • Avoid breakout/momentum plays — they fail 70%+ of the time in chaos
Checking the Regime Before You Trade
The regime detector runs on the Market Pulse bar on the Today page, giving you instant context before you look at any individual setup. It's the first gate in QSA's signal pipeline.
Before acting on any scanner signal, check the regime. An S-grade momentum setup in CHAOS regime should be treated with extreme caution. A B-grade mean reversion setup in CHAOS might actually be the better trade.
The regime doesn't tell you what to trade. It tells you which signals to trust.
