Mainland Stock Screen Combining RSI, Daily Gains, and a KDJ Cross

Summary

This post describes a mainland Chinese stock selection rule combining an RSI reading below 65, a daily gain greater than one percent, main-board membership, and a newly formed KDJ bullish crossover. It frames the filters as a way to find stocks with a positive short-term move and a possible shift in momentum. The article includes example indicator formulas and Python-style selection logic, but presents no historical test, comparison with a benchmark, or performance evidence. Its stated expectation of favorable future performance is therefore not supported by reported results.

The post warns that fixed thresholds can become unsuitable as market conditions change and that technical indicators can generate false signals. It suggests adding fundamental measures, adjusting the rules to market conditions and stock characteristics, and applying risk controls. There are also inconsistencies between the prose and code: the text describes RSI below 65 as oversold, while the code’s filters and moving-average conditions do not fully align with the described criteria. The examples should therefore be treated as a screening concept requiring validation, not as a fully specified or verified strategy.

Key ideas

• The proposed screen combines RSI below 65, a daily gain above one percent, main-board status, and a fresh KDJ crossover.
• The post provides sample formulas and code but no backtest evidence or measured returns.
• Fixed thresholds and technical indicators can produce signals that fail as market conditions change.
• The prose and example code contain mismatches that require review before the screen is implemented.
• The author suggests adding fundamental filters, adapting to market conditions, and applying risk controls.
