MACD and 15-Minute Momentum Filters for A-Share Selection

Summary

This A-share screening rule selects stocks with MACD above its zero line, a price below 12 yuan, and a shortening green MACD histogram on a 15-minute chart. The article says to run the screen before each trading day opens. It provides indicator formulas and sample Python intended to illustrate the filters, but gives no historical test, return figures, or comparison with a benchmark.

The suggested interpretation is that a positive MACD reading combined with a contracting negative histogram may help identify stocks with potential upward movement. There is an internal ambiguity: a histogram described as green and shortening is usually negative, while the sample code tests for positive MACD values and also imposes a particular relationship to the signal line. The examples should therefore be checked against the intended chart convention before use. The article also notes that market conditions can invalidate technical signals and that the screen omits fundamentals and liquidity; it suggests adding those dimensions.

Key ideas

• The proposed screen combines MACD above zero, a share price below 12 yuan, and a shortening green histogram on a 15-minute chart.
• The screen is intended to run before each trading day opens.
• The article supplies formulas and sample code but reports no backtest or performance evidence.
• The description and code may differ in their treatment of histogram direction, so the signal definition needs verification.
• The method relies on technical data and may miss liquidity and fundamental risks.
