A-Share Screen Using Positive MACD, Low Price, and Three Down Days

Summary

This note describes a daily stock screen combining MACD above zero, a share price below 12 yuan, and three consecutive declines in closing price. It interprets the MACD condition as a positive trend context and the recent losses as a possible short-term pullback that could invite a contrarian entry. The proposed screen is meant to run before the market opens, though the example code also refers to intraday data and a 10:00 filter.

The article offers indicator formulas and illustrative code, but it provides no backtest results or evidence that the conditions generate returns. Its own risk discussion cautions that the approach relies on technical signals, uses only a short price window, and may react to noise. It suggests supplementing the screen with fundamental and other technical measures, and filtering for liquidity or unusual market conditions. The example implementation should be checked carefully: its stated consecutive-decline condition does not clearly match the code expression shown.

Key ideas

• The screen combines MACD above zero with a share price below 12 yuan and three consecutive declining closes.
• The author frames the falling prices as a possible short-term pullback that could support a contrarian entry.
• The note provides indicator formulas and sample screening code but reports no strategy performance.
• The article warns that short lookbacks, technical-only signals, and market noise can weaken the selection.
