A-Share Screen Using RSI, Three Consecutive Declines, and Daily Range

Summary

This technical screen seeks stocks with a 14-period RSI below 65, three consecutive down sessions, and a daily high-low range above 1% of the previous close. The accompanying formula and sample code also add conditions for a price decline greater than 2% and a close below the 60-day moving average. These extra filters make the examples more restrictive than the short description of the selection rule.

The article frames the method as a simple way to find shares with weakening short-term price action and notable movement, but does not provide backtest results or evidence of profitability. It warns that the screen omits company fundamentals and may be unstable during abnormal market moves. It suggests combining technical and fundamental analysis and applying risk controls. The sample code’s definition of three consecutive declines should be checked against the intended timing, since the listed comparisons appear to test prior candles and can differ from a current three-session decline condition.

Key ideas

• The stated screen combines RSI below 65, three consecutive down sessions, and a daily range above 1%.
• The sample implementation adds a greater-than-2% decline and a close below the 60-day average.
• No performance testing is reported, and the author cautions that fundamentals and abnormal moves are not covered.
• The example’s candle comparisons may not match the stated three-session decline rule.
