A-Share Screening with Opening Gaps, Indicator Crossovers, and Volume Ratio

Summary

This Chinese A-share screening proposal combines the 9:25 opening move, technical-indicator crossovers, and relative trading activity. It selects stocks with an opening gain below 6% versus the prior close, ranks volume ratio and takes the top 100, and seeks simultaneous bullish crosses involving MACD, KDJ, and RSI. The article describes the combination as a way to find stocks with buying interest and improving technical signals while avoiding the largest opening gaps.

The post cautions that this screen leaves out company finances and industry outlook, and that its measure of capital strength may be inaccurate. It suggests adding fundamental and industry factors and considering other activity measures. The supplied Python example is incomplete: it begins indicator calculations but ends mid-expression, so it does not provide a reproducible implementation of the full rule. No backtest, trade sample, or performance evidence is supplied. The screen should therefore be read as a proposed selection rule, not as evidence of an effective or profitable strategy.

Key ideas

• The proposed screen combines an opening gain filter with volume-ratio ranking and technical crossovers.
• It ranks stocks by volume ratio and selects from the top 100.
• The article describes bullish signals involving MACD, KDJ, and RSI, but the precise crossover conditions are unclear.
• Company finances, industry prospects, and the accuracy of the activity measure are cited as limitations.
• The sample Python implementation is truncated, and the post supplies no backtest results.
