A-Share Screening with MACD, Positive P/E, and Auction Buying Pressure

Summary

The document describes a Chinese A-share screening rule that combines MACD above zero, positive price-to-earnings ratio, and positive net buying attributed to major participants during the opening auction. It presents the MACD components and an OBV-based proxy for buying pressure, then sketches a filter and ranking workflow using daily stock data. The proposed interpretation is that MACD indicates an upward trend, positive P/E excludes firms with negative earnings, and auction buying may signal market interest.

The article gives no backtest, performance figures, or empirical validation, and its explanations of what the signals imply should be treated as hypotheses. It notes that auction flows can reflect sentiment and that screening may miss candidates. Its sample Python workflow assumes fields and calculations that may not be available or aligned in the cited data source, so implementation details need independent verification. The author suggests adding fundamental information and other indicators, while emphasizing that the rule should be adjusted to circumstances.

Key ideas

• The screen requires MACD above zero, positive P/E, and positive auction net buying.
• The article uses an OBV difference from its moving average as a proxy for buying pressure.
• It suggests sorting qualifying stocks by percentage change, but provides no evidence that this improves results.
• Auction buying may be noisy, and the screen can omit relevant stocks.
• The proposed conditions are a starting point for evaluation rather than a validated strategy.
