Range compression and the breakout that follows
Posted: Sat Oct 31, 2026 8:58 pm
When a pair's range narrows to a fraction of its usual size, a larger move often follows. It is one of the more reliable patterns in short-term trading, though it is far from perfect.
The logic is that low volatility cannot last forever. Orders build on both sides, and when something triggers a break, the move can be sharp.
The practical trouble is direction and timing. Compression can last for an hour or more, and the first breakout is often false. Price pokes out, triggers entries, and returns.
A cautious approach is waiting for a close outside the range with an expanding spread-adjusted move, not just a tick through the edge. Another is placing entries at the opposite edge after a failed breakout.
Position sizing matters here too. Stops are typically just inside the range, so the risk per trade can be small, but repeated false breaks add up.
Tracking compression events, with the range size relative to average and the outcome, will show whether the pattern pays on the pairs of interest.
How are compression and breakouts handled, and what filters reduce false breaks?
