A-Share Screen Combining RSI, Seven Down Sessions, and Holder Concentration

Summary

The post proposes a Chinese A-share stock screen using three conditions: RSI below 65, seven consecutive sessions in which the close is no higher than the open, and a holder-concentration measure between 20% and 70%. It also provides example code intended to retrieve market data, exclude certain stocks, apply the conditions, and sort qualifying names by concentration.

The author presents the combination as a technical screen with a concentration filter, but gives no backtest, return figures, or validation. The explanation has internal inconsistencies: it describes concentration as below 20% while also requiring it to exceed 70%, and the final code applies the opposite bounds. The data calls and implementation are not demonstrated to work, and the post itself notes that financial health, industry conditions, liquidity, and other fundamentals are not adequately covered. Treat the rules as an unverified screening idea.

Key ideas

• The proposed screen combines RSI below 65 with seven consecutive bearish sessions.
• It adds a holder-concentration band, though the written thresholds conflict with the code and each other.
• The example sorts selected stocks by concentration but provides no tested performance results.
• The post recommends broader fundamental, industry, and liquidity checks.
• The data and code are presented as references rather than a validated implementation.
