A-Share Stock Screening with Positive MACD, Low Price, and Auction Buying

Summary

This A-share screening idea selects stocks before the open when MACD is above zero, the quoted price is below 12 yuan, and net buying by large participants during the auction is positive. It combines a momentum signal with a price cutoff and an order-flow condition. The document offers example indicator formulas and a Python outline, but does not report a backtest or performance results.

The author cautions that the rules are simple, may be affected by short-term price moves and noisy data, and omit company fundamentals such as valuation measures. It suggests adding fundamental indicators or other technical conditions. The proposed screen is therefore a basic selection heuristic, not evidence that selected stocks will outperform or carry lower risk. Its usefulness also depends on how the auction net-buy measure is defined and whether the cited data source provides reliable, timely values.

Key ideas

• The screen requires MACD to be above zero, price below 12 yuan, and positive auction net buying by large participants.
• It is intended to run before the market opens each trading day.
• The document provides example MACD calculations and a sample data workflow, but no performance test.
• The rules omit fundamental analysis and may be sensitive to short-term noise and market changes.
