Screening Stocks by Opening Gap, Volume Ratio, and Bollinger Band Position

Summary

This stock-screening proposal combines a modest opening gap with relative trading activity and a Bollinger Band location. It selects stocks whose 9:25 a.m. price rise is below 6%, ranks candidates by volume ratio with the top 100 prioritized, and describes a “curved” price condition as trading between the Bollinger middle and upper bands. The article interprets higher relative volume as potential buying interest and the band location as a way to identify price behavior, though these interpretations are not demonstrated with data.

The post suggests supplementing the screen with turnover and trading volume, and checking Bollinger-based selections with MACD or RSI. It also notes that apparent strength or limited volatility can occur in unfavorable market conditions or amid distribution by large traders. No results, backtest, benchmark, or precise combined rule for the opening-gap condition appears in the final selection logic, which focuses on the volume and band filters. Treat it as a screening hypothesis requiring clearer definitions and validation.

Key ideas

• Prioritize stocks with volume ratios among the top 100.
• Use a price position between the Bollinger middle and upper bands as a selection condition.
• Limit the 9:25 a.m. price rise relative to the prior close to below 6%.
• The article proposes confirming volume and band signals with other indicators.
• It provides no backtest and warns that these signals can also occur in unfavorable conditions.
