A-Share Screen Using RSI, Order Flow, KDJ, and Recent Returns

Summary

This document outlines a Chinese A-share screening rule that combines an RSI below 65, an external-to-internal trading volume ratio above 1.3, and a KDJ K value below 20. Its Python example adds a recent return filter, excluding stocks with nonpositive or especially large gains over the stated lookback. It also describes using current quote data to assess the order-flow ratio and retaining candidates that meet every condition.

The source presents the screen as a technical filter and gives indicator formulas and sample implementation ideas, but it provides no measured backtest or evidence that the screen predicts returns. The described KDJ and order-flow measures may be noisy or time sensitive, and the document acknowledges that technical signals can be affected by false breakouts and omit fundamentals. It suggests evaluating fundamental measures and broader market conditions alongside the technical rules. The code references are illustrative; indicator calculations and data fields should be checked against the chosen data source before use.

Key ideas

• The proposed screen combines RSI, external-to-internal trading volume, and KDJ thresholds.
• The sample implementation also filters on recent share price returns.
• The document offers formulas and example code but reports no strategy performance evidence.
• Technical indicators can be time sensitive, noisy, and incomplete without fundamental analysis.
