Volatility isn't random — it breathes. Tight, boring ranges build pressure that releases in fast, tradeable moves, then settles again. Reading that rhythm is half of timing.
Markets alternate between volatility contraction — tight, quiet, low-range periods — and volatility expansion — big, fast, wide-range moves. This cycle repeats endlessly, and the transition between the two is where a lot of opportunity (and risk) lives.
The coil
Contraction shows up as narrowing ranges, shrinking Bollinger Bands, and falling realized volatility — the market "coiling" as energy builds (Bollinger Bands, ATR). These quiet phases feel boring and often frustrate traders into overtrading a dead tape (the discipline of sitting out). But a tight coil is potential energy.
The release
Expansion is the release: a breakout from the coil that runs, often fast, as the built-up pressure resolves in one direction (breakout vs fakeout). "Volatility contraction precedes expansion" is one of the more reliable rhythms in markets — quiet doesn't last, and neither does chaos (why volatility clusters).
The market inhales in tight, boring ranges and exhales in violent moves. The boredom isn't the absence of a trade — it's the setup for one.
Trading the cycle
In contraction, expect chop and either fade the range or wait for the break; in expansion, expect follow-through and trade with the move, sizing for the wider swings (range trading, trend following). Dealer gamma amplifies this — positive-gamma dampens (contraction), negative-gamma amplifies (expansion) (positive vs negative gamma).
