A-Share Screen Using RSI, Seven Down Days, and a Rising 30-Day Average

Summary

This document describes a technical screen for Chinese stocks that combines an RSI reading below 65, seven consecutive sessions in which the close is below the open, and an upward-sloping 30-day moving average. It gives indicator formulas and a Python example intended to retrieve market data and filter stocks, with additional restrictions on board, exchange, and market capitalization.

The rationale is to combine a short-term sequence of weak sessions with a longer-term rising average, while the RSI condition helps define the candidate set. The post warns that a technical-only approach may miss company fundamentals and unexpected news, and suggests adding financial and market information. It provides no backtest or evidence of profitability. Some implementation details appear inconsistent with the stated conditions, including how the moving-average direction is checked, so the code should not be assumed to faithfully implement or validate the screen.

Key ideas

• The proposed screen requires RSI below 65 and seven consecutive sessions with closes below opens.
• It also requires the 30-day moving average to be rising.
• The example adds exchange, board, and market-capitalization filters beyond the core rule.
• The author warns that technical signals can overlook fundamentals and unexpected news.
• No performance evidence is given, and the code may not fully match the described logic.
