Combining RSI, Large-Order Flow, and Limit-Down Screening

Summary

This Chinese-language post describes an equity screen using RSI below a specified ceiling, a product of price change and a large-order net-flow measure above a threshold, and a prior-day opening-auction matched price at the limit-down price. The stated intent is to combine a technical condition and order-flow proxy with an unusual market event. The post also includes a sample data-filtering approach and suggests additional review of market capitalization, valuation, and other indicators before relying on the selections.

The author warns that the screen may select recently listed companies or firms with very high valuation, and notes that the opening-auction limit-down observation captures only part of a stock’s market context. No backtest, performance statistics, or evidence of predictive advantage is presented. Definitions, data quality, and timing for the flow and auction variables would need verification before implementation, and the screen should be treated as a hypothesis for further analysis.

Key ideas

• The screen combines an RSI ceiling, a price-change and large-order net-flow condition, and a prior-session opening-auction limit-down observation.
• The post presents the rules as a way to combine technical and market-condition information.
• It flags exposure to recently listed and highly valued companies as a risk.
• The author suggests adding valuation, market-capitalization, and other technical or market filters.
• No backtest or trading-performance evidence is supplied.
