A-Shaped Reversal Screen After a Sharp Intraday Decline

Summary

This Chinese-language post describes a short-term stock screen combining a minimum daily amplitude, a daily decline constrained to a narrow interval, and a reversal candle pattern. The stated pattern requires the current session to open below the previous session’s low and close above the previous session’s high, producing a strong bullish reversal after the decline. The post supplies example indicator conditions and Python-style selection logic for scanning daily stock data.

The idea is to look for a potential short-term rebound after pronounced weakness. The examples are references rather than a validated implementation, and the post includes inconsistencies between its written definition, indicator formula, and code—for example, the formulas do not uniformly encode the stated prior-high close condition. No performance results are given. The author cautions that the screen ignores fundamentals and broader market conditions, and suggests incorporating risk controls and portfolio considerations.

Key ideas

• The screen looks for stocks with daily amplitude above a threshold and a decline within a specified range.
• Its reversal setup requires an opening price below the prior low and a close above the prior high.
• The proposed use is short-term stock selection for a possible rebound.
• The example formulas and code do not consistently match the written reversal definition.
• The post supplies no performance evidence and notes that the screen omits fundamentals and broader market risks.
