Stock Screen Combining RSI, Bid–Ask Volume, and KDJ

Summary

This Chinese stock-selection note combines three conditions: a 14-period RSI below 65, first-level bid volume greater than first-level ask volume, and the KDJ K line below 20. The author presents the rules as a blend of technical readings and order-side volume, with the low K value intended to identify a potential reversal while bid-side volume signals stronger buying interest.

The note includes example indicator formulas and a Python sketch, but gives no backtest, trade outcomes, or market-specific validation. It acknowledges that the screen omits financial statements and business quality, and that KDJ is not sufficient on its own to decide when to trade. It recommends evaluating company fundamentals and adapting the thresholds to different market conditions. The described conditions generate candidates; the text does not specify entry sizing, exits, or risk controls, and the sample implementation should be checked against the exact data definitions used.

Key ideas

• The screen requires RSI below 65, bid-side volume above ask-side volume, and KDJ K below 20.
• It combines price-derived indicators with order-side volume information.
• The author frames the low K reading as a possible reversal context, not a standalone trading decision.
• No backtest or performance evidence is reported.
• Fundamental review and context-sensitive use of the indicators are suggested.
