A-Share Stock Screen Using RSI, Trading Flow, and a Rising Average

Summary

This Chinese-language note presents an A-share stock screen combining three conditions: RSI below 65, the ratio of buy-initiated to sell-initiated trading volume above 1.3, and a rising 30-day moving average. It also shows a market-capitalization range in its reference query and provides example implementations for a screening platform and Python. The stated rationale is to combine a momentum indicator, a trading-flow measure, and a trend filter.

The examples are not fully consistent: the Python section uses a different calculation as a proxy for trading flow and applies additional price and volume checks, while the prose centers on the three screening criteria. The note warns that a rising average is based on past prices and cannot reliably forecast future moves, and that the screen does not remove market risk. It provides no historical test results or evidence that the criteria generate returns. It suggests adding other indicators or macroeconomic and industry context, and reviewing the rules as conditions change.

Key ideas

• The core screen requires RSI below 65, a trading-flow ratio above 1.3, and a rising 30-day moving average.
• The reference query also filters for a stated range of circulating market capitalization.
• The sample implementations add conditions and use different methods to represent trading flow.
• The note cautions that historical moving averages may not predict future prices and that the screen cannot eliminate market risk.
• No backtest or performance evidence is provided.
