A-Share Screening with RSI, Order Flow, and MACD Filters

Summary

This article describes a Chinese A-share stock screen combining a relative strength index below 65, an external-to-internal trade ratio above 1.3, and a negative MACD reading from two sessions earlier. It interprets the RSI condition as avoiding overbought stocks, the trade ratio as a sign of buying pressure, and MACD as a trend check. The indicators are presented as complementary technical filters.

The article suggests making the screen more complete with company financials, market and sector context, and ongoing monitoring. It also gives example indicator definitions and Python-oriented data retrieval guidance. The document does not report a backtest or performance evidence, and the trade ratio's interpretation as foreign buying is not established by the screen itself. Its discussion acknowledges that a technical-only approach can select weak companies; data quality and implementation details may also affect results.

Key ideas

• The screen requires RSI below 65, an external-to-internal trade ratio above 1.3, and MACD below zero two sessions earlier.
• The article treats RSI as an overbought filter and the trade ratio as a measure of buying pressure.
• It recommends adding financial analysis, broader market context, and ongoing monitoring.
• No performance results are provided, and the article warns that technical filters omit company fundamentals.
