A-Share Screen Using RSI, Prior Main-Flow Data, and Opening Gain

Summary

This stock-selection rule screens for shares with a 14-period RSI below 65, positive prior main-fund-flow data, and an indicated gain below 6% at 9:25. The accompanying discussion presents the conditions as a way to avoid stocks that appear too active at the opening while retaining stocks with comparatively moderate price movement. It also refers to excluding special-treatment stocks and sorting selected names by heat, though it does not define that ranking measure.

The post supplies an illustrative implementation approach and suggests adding indicators, company fundamentals, or sector constraints. It warns that the screen omits fundamental quality and that price indicators cannot reliably predict future prices; strict time-based filters can also leave fewer candidates and concentrate risk. The document provides no historical test, trade rules, holding period, transaction-cost analysis, or performance evidence. Its data definitions and code example would need careful validation before use, especially because the described main-flow and pre-open measures may depend on the platform and data source.

Key ideas

• The screen combines RSI below 65, positive prior main-fund-flow data, and a pre-open gain below 6%.
• The post describes the filters as a way to avoid highly active opening conditions.
• It flags the absence of fundamental analysis and the limited predictive power of price indicators.
• No backtest, execution plan, holding period, or performance results are supplied.
• The proposed data fields and implementation require platform-specific validation.
