Stock Screening with RSI, Bid–Ask Volume, and Turnover

Summary

This Chinese-language post describes an equity screen combining three conditions: a 14-period RSI below 65, first-level bid volume greater than first-level ask volume, and turnover between 3% and 12%. It presents the combination as a way to find stocks with relatively favorable technical conditions and active trading. The article includes formula and Python examples, although the Python filter does not apply the RSI condition when constructing its selection mask, so the implementation is incomplete relative to the stated rules.

The post gives no backtest, performance figures, or evidence that the screen predicts returns. It notes that turnover can be unstable and that strict thresholds may leave too many or too few candidates; turnover alone also does not fully describe activity. Suggested refinements include adding volume and fundamental measures and applying position limits or exit controls. These are general suggestions rather than tested improvements, and the screen does not specify portfolio construction or execution rules.

Key ideas

• The screen requires RSI below 65, first-level bid volume above first-level ask volume, and turnover from 3% to 12%.
