A-Share Stock Screening with RSI, Order Flow, and Bollinger Bands

Summary

This Chinese A-share screening idea combines a relative strength index threshold, a price-change and large-order-flow condition, and a Bollinger Band location. It selects stocks with RSI below 65, a positive product of percentage change and a measure of net large-order volume, and a close between the middle and upper Bollinger bands. The stated rationale is to combine technical strength with an indication of buying activity.

The post provides example indicator definitions and a code sketch, but no backtest, trade rules beyond the screen, or evidence of returns. It warns that technical signals can omit fundamental risks and that order-flow measures may be unreliable or influenced by large participants. Suggested extensions include adding other indicators or fundamental filters and diversifying the resulting portfolio. The screening conditions therefore describe a candidate-generation method, not a complete or validated trading system.

Key ideas

• The screen requires RSI below 65 and a positive interaction between price change and large-order net flow.
• It selects stocks closing above the Bollinger middle band and below the upper band.
• The method combines price-based indicators with a proxy for capital flows.
• The source provides no backtest or evidence that the screening rules produce positive returns.
• It suggests adding fundamental checks and portfolio diversification to address limitations.
