Screening Shanghai-Listed Stocks by Intraday Range and Drawdown

Summary

This post presents a short-term screen for stocks whose codes begin with 60, whose daily high-low range exceeds 1% of the previous close, and whose session low is between 4% and 5% below that close. It frames the range condition as a way to find volatile shares and the drawdown band as a way to identify stocks experiencing a sharp intraday decline. The post also suggests combining the screen with fundamentals and other technical measures.

The article supplies illustrative indicator logic and a code example, but gives no backtest, market comparison, or evidence that the selected shares tend to recover. Its description of stocks in the drawdown band as having potential is therefore speculative. The screen uses only recent price action and a particular stock-code prefix, which narrows coverage and says little about longer-term direction or company quality. The implementation details should also be checked carefully against the intended data fields and market conventions before use.

Key ideas

• The screen selects stocks whose codes begin with 60.
• It requires a daily high-low range above 1% of the prior close.
• It selects stocks whose session low is 4% to 5% below the prior close.
• The post presents volatility and sharp declines as screening cues, not proven return predictors.
• It recommends adding other technical and fundamental information.
