A-Share Screen for Positive MACD, Low Price, and a Sharp Intraday Drop

Summary

This document describes a daily A-share screening rule combining a positive MACD condition, a share price below 12 yuan, and a maximum daily decline between 4% and 5%. It says to run the screen before 10 a.m. each trading day. The intended idea is to combine a trend indicator and a low nominal price with a recent sharp drop when selecting stocks.

The article gives example indicator formulas and Python-oriented screening guidance, but no backtest results or evidence that the rule is profitable. Its explanation flags market uncertainty and possible noise or error in short-term decline data. It suggests adding other technical and company financial measures, while leaving those additions unspecified. The example data handling and formula descriptions may require adjustment to match the intended definition of a daily maximum decline and the available data source.

Key ideas

• The screen requires MACD to be above its zero axis and price to be below 12 yuan.
• It filters for a daily maximum decline between 4% and 5%.
• The stated screening time is before 10 a.m. on each trading day.
• The article identifies market uncertainty and short-term data noise as limitations.
• It proposes adding technical and fundamental factors but provides no tested evidence.
