A-Share Screen for Seven Losing Sessions and a Sharp Intraday Drop

Summary

The screen targets Chinese A-share stocks with an RSI below 65, seven consecutive sessions meeting a bearish-candle condition, and an intraday low between 4% and 5% below the reference price. A later version adds a circulating market-value range of 5–200 billion yuan and mentions fundamental filters such as valuation and return on equity. The accompanying implementation sketch also excludes some stocks and describes using daily price data.

The rationale is a possible rebound after sustained weakness, but the document supplies no backtest, selected-stock examples, or measured outcomes. It flags timing risk and the omission of company fundamentals. The written rules and sample implementation are not fully consistent: the text describes consecutive down days, while the code checks closes against opens, and its intraday-drop calculation uses the day’s close as the denominator. These details need resolution before reproducing or evaluating the screen.

Key ideas

• The proposed screen combines RSI, a seven-session bearish pattern, and a narrowly bounded intraday decline.
• A later specification adds a circulating market-value range and suggests fundamental filters.
• The stated rationale resembles buying after a pronounced decline, but no performance evidence is supplied.
• The prose and example code differ in how they define consecutive losing sessions and intraday drawdown.
• The article identifies timing risk and the possibility of overlooking company fundamentals.
