A-Share Momentum Screening with MACD, Large-Order Flow, and a Rising Average

Summary

This proposed A-share screen looks for stocks with MACD above its zero line, positive price change combined with positive net flow attributed to very large orders, and an upward-sloping 30-day moving average. The post frames MACD as a trend signal, order flow as an indication of capital inflows, and the rising average as confirmation that price is advancing. It includes formula references for MACD, price change, order flow, and the moving average, along with sample Python that aims to assemble a qualifying list.

The author cautions that indicator-only selection can omit company fundamentals and remain exposed to economic, policy, and market shocks. Suggested refinements include adding profitability and growth measures, making the moving-average test more objective, and defining exit controls. The sample calculations and data periods are not fully explained, and the post supplies no backtest results or evidence that the filters predict returns. The method is therefore a screening hypothesis, not a validated trading system.

Key ideas

• The screen requires MACD above zero, positive price change and large-order net flow, and a rising 30-day average.
• The post treats these conditions as trend and capital-flow filters for A-share stocks.
• It provides indicator formulas and sample Python for assembling candidates.
• The author identifies missing fundamentals and external market shocks as risks.
• No backtest or performance evidence is provided, and the sample implementation needs careful validation.
