Breaking 20-day support after tight range - bearish expansion
The close-below-20-day-low condition requires the current bar to close beneath the lowest close of the past 20 sessions — a definitive structural breakdown, not a wick. The tightness filter checks that the current 20-day low is within 5% of the 20-day low recorded 11 candles ago, confirming the range was genuinely compressed before the break. Volume above 1.2x the 20-period average validates that the breakdown has participation; without this, a single down day on light volume could trigger the price condition alone. All three conditions must be true simultaneously, which is why the stock count is low.
The value of this screen is its specificity: it only fires after a period of price compression, not on a random down day. A stock in free fall will not match because its 20-day low moves lower continuously. This screen catches stocks that consolidated, suggesting indecision or accumulation, then resolved bearishly. The most dangerous failure mode is a false breakdown: price closes below the 20-day low on the signal day, then reverses and reclaims the level within 1-2 sessions — trapping short sellers. This happens most often when the break coincides with a broad market reversal. Compare to 20-Day Consolidation Breakout for the bull-side equivalent, and Near 52-Week High for broader trend context. New 52-Week High helps confirm whether this breakdown is counter-trend.

This screen identifies stocks breaking below a 20-day support level after a tight consolidation range — a bearish expansion signal. The prior range tightness (20-day low within 5% of where it was 11 sessions ago) confirms that price has been coiling; a break below that floor with elevated volume signals the coil releasing to the downside. Currently 1 stock matches, making this a highly selective signal. Swing traders and short sellers use it to find low-risk entries after confirmed structure failure.
