Combining MACD, Three Down Days, and a Pre-Open Price Cap

Summary

This Chinese stock-selection proposal combines a MACD reading above zero, three consecutive down days, and a price gain below six percent at 9:25. Its rationale is to find stocks with a positive broader technical signal that have recently weakened, while avoiding a sharp pre-open rise. The post presents the combination as a technical screen and suggests that other indicators, such as RSI or KDJ, could be added.

The article warns that MACD can give misleading signals, a short losing streak may have causes unrelated to a rebound, and a strict opening-gain cap could exclude strong stocks. Its sample code does not clearly implement the advertised three consecutive down days or the exact 9:25 price-change condition, and it describes MACD components in a way that may differ from the headline rule. No backtest results or evidence of a safety margin are supplied. The conditions and timing would need precise definitions and validation before the idea could support a trading decision.

Key ideas

• The proposed screen requires MACD to be above zero, three consecutive declining sessions, and a pre-open gain below six percent.
• The rationale combines a positive indicator reading with recent weakness and a limited opening move.
• The post identifies false MACD signals and missed opportunities from rigid price limits as risks.
• It suggests combining the screen with other indicators, but gives no measured evidence of improvement.
• The included code does not clearly match all of the conditions described in the headline and prose.
