A-Share Stock Screen Using Positive MACD, Low Price, and Afternoon Fund Flows

Summary

This Chinese-language post outlines a daily A-share stock screen combining three conditions: MACD above zero, share price below 12 yuan, and afternoon net inflows from large orders. It says the screen is run before 10 a.m. each trading day. The rationale is to combine a technical trend signal and a low-price filter with a measure intended to reflect investor sentiment and incoming capital.

The post warns that large-order flow data may be manipulated and may make results unstable. The conditions may also exclude strong stocks, including those rising through consecutive limit-up sessions. It suggests adding other sentiment measures, such as margin financing and securities lending balances or broader fund flows, and tailoring indicators to industries or market sectors. The included formula and Python example are references rather than a validated implementation: the example uses moving-average crossover variables and turnover changes alongside MACD, so it does not cleanly match the stated screen. No backtest results or performance evidence are provided.

Key ideas

• The proposed screen requires MACD above zero, a share price below 12 yuan, and afternoon net buying by large orders.
• The author frames the conditions as a combination of technical signals and a proxy for market sentiment.
• Large-order flow can be manipulated, which may reduce the screen’s stability and accuracy.
• The filters may miss stocks showing strong short-term momentum, including consecutive limit-up movers.
• The post suggests adding other flow measures and tailoring the screening criteria to sectors, but supplies no performance test.
