A-Share Screen Using Intraday Range, Trading Volume, Opening Gap, and RSI

Summary

This proposed A-share screen looks for stocks with an amplitude above 1, current volume above 10,000 lots, an opening price above the prior close, and an RSI below 65. The explanation treats range and volume as signs of activity, the opening gap as a sign of market interest, and the RSI threshold as a way to avoid selecting especially overbought names. It also suggests combining technical signals with market context and company analysis.

The source cautions that active, wide-ranging stocks can carry higher volatility and that RSI cannot reliably predict future direction. It recommends additional indicators, fundamental review, risk controls, and periodic backtesting, but provides no test results. The accompanying code does not clearly implement the stated screen: its volume condition checks whether any observation in the history falls below the threshold, and its field references and RSI timing are not clearly aligned with the prose. Treat the setup as a screening idea requiring validation, not as demonstrated evidence of an edge.

Key ideas

• The screen combines a minimum price range and volume with a positive opening gap and an RSI ceiling.
• The source notes that wide price swings and active trading can raise risk.
• RSI is described as a context indicator rather than a reliable forecast of future direction.
• The sample code does not clearly match the stated filters and requires verification.
• No backtest results or evidence of profitability are provided.
