Volatility & Risk — Sizing Trades to the Regime
Volatility is the size of the next move, not its direction. Treating it as a separate variable from price action — used to size positions and place stops dynamically — is what separates durable systems from fragile ones.
Overview
A common practitioner workflow uses volatility as a regime classifier first and a risk-management input second. ATR or Bollinger band-width readings at multi-period lows signal compression — the market is coiling, and a meaningful expansion typically follows. Conversely, ATR at multi-period highs signals a regime where stops sized for quiet markets get triggered repeatedly. Beyond regime, volatility readings are the natural input to position-sizing — risking a fixed-dollar amount through a stop that's a multiple of ATR keeps risk per trade roughly constant across market states. This hub indexes the volatility indicators, the patterns whose validity hinges on volatility behaviour, and example stocks that produce clean volatility transitions.

FAQ
What's a Bollinger squeeze?
A Bollinger squeeze occurs when band width drops to a multi-period low, indicating volatility compression. Markets rarely stay quiet for long, so a squeeze is often a precursor to a meaningful expansion in either direction.
Should I use ATR-based stops or fixed-percentage stops?
ATR-based stops adapt to the regime — a 1× ATR stop is the right size in a quiet market and the same stop in a noisy market is too tight. Fixed-percentage stops are simpler but tend to over-tighten in calm periods and over-loosen during volatility spikes.
