A-Share Screen Combining Positive MACD, Low Price, and KDJ Conditions

Summary

This Chinese-language post outlines a daily stock screen for A-shares using a positive MACD condition, a share price below a stated threshold, and a recent KDJ bullish crossover. It describes running the selection before the trading session and gives reference formulas and Python-style logic that also constrain the opening price to a band around a short moving average. The stated approach combines trend or momentum indicators with a nominal price filter and an opening-price condition.

The post warns that inaccurate data, market volatility, and indicator conditions can affect selection results, and suggests adding fundamental or valuation measures and reviewing risk. It offers no backtest results or evidence that the screen improves returns. Its descriptions and code are not fully aligned: the prose calls for a recent KDJ crossover, while the sample logic checks relative indicator levels; the MACD wording also differs between a zero-axis crossover and simply being positive. These details need resolution before implementation, and the price threshold alone does not control risk.

Key ideas

• The proposed screen combines positive MACD, a low share price, and a bullish KDJ condition.
• The reference implementation adds an opening-price filter around a short moving average.
• The post identifies data quality, market movements, and indicator dependence as risks.
• The written crossover criteria and sample code use differing condition descriptions, so the rules are ambiguous.
• No historical performance evidence is provided.
