Bearish Breakaway Gap: definition and measured success rate
Data as of 31.07.2026 · back-test since 05/2019
A bearish breakaway gap occurs when price opens clearly below a prior support level, leaving a visible gap, and stays below it. Supply overwhelmed the level overnight, skipping the intermediate prices entirely. In chartval's back-test, it worked in 42 of 100 comparable cases (2,922 occurrences).
How does a bearish breakaway gap form?
A defended floor gives way at the open rather than during the session. If the gap does not close in the following days, the old support has flipped to resistance and a new downward leg is underway.
How reliable is the bearish breakaway gap?
In chartval's historical back-test across 274 stocks, ETFs and cryptocurrencies, the bearish breakaway gap reached a 5 percent move in the signal direction before a 5 percent counter-move in 42 of 100 cases (2,922 occurrences evaluated since 05/2019; data as of 31.07.2026). Past statistics are not a reliable indicator of future results.
Measurement: a case counts as a hit when price moved 5 percent in the signal direction before moving 5 percent against it, based on closing prices, within a maximum of 120 candles after the trigger.
