Bullish Breakaway Gap: definition and measured success rate
Data as of 31.07.2026 · back-test since 07/2019
A bullish breakaway gap occurs when price opens clearly above a prior resistance level, leaving a visible gap on the chart, and holds that level. The market repriced overnight — demand was strong enough to skip the intermediate prices entirely. In chartval's back-test, it worked in 54 of 100 comparable cases (3,839 occurrences).
How does a bullish breakaway gap form?
News or accumulated demand meets a well-tested ceiling: instead of grinding through it, price jumps over it at the open. Genuine breakaway gaps start moves out of bases; gaps that fill quickly were exhaustion, not breakaway. Volume on the gap day is the key witness.
How reliable is the bullish breakaway gap?
