How the Bollinger Squeeze Breakout screen works
The Bollinger Squeeze Breakout screen is a breakout setup: bB(20,2) width at a 6-month low, then close above the upper band. A stock qualifies on a given day when every condition is true at the close: bb width ≤ 1.1× its 126-day min (prior day); close > upper Bollinger Band. To keep results tradable, only S&P 500 and Nasdaq-100 members above $5 with more than $5M of average daily dollar volume are included.
Across 518 tickers from 2021-10-13 to 2026-10-12, the screen fired 2,456 times on 508 different stocks. 51.5% of signals were higher five sessions later, ranking #21 of 25 screens on SetupHits by hit rate. The average 5-day move was +0.16% (median +0.12%), behind SPY's +0.23% over the same days, and the equal-weight trade curve's worst drawdown was -46.4%.
Setup is copy-paste: TradingView, ThinkorSwim versions are listed above. In TradingView use the string in the Stock Screener filter or a Pine condition; in Finviz append the filter codes to the screener URL; in ThinkorSwim paste the thinkScript into a Stock Hacker custom study filter. Platforms compute indicators slightly differently, so expect small differences in the hit list.
Treat these numbers as context, not a forecast. The backtest uses daily bars, ignores commissions and slippage, overlaps signals on the same stock, and tests today's index members back in time, which adds survivorship bias. A mostly rising 2021–2026 market also lifted most long setups.
