A-Share Screen for Large Ranges, Positive Weekly MACD, and Seven Down Closes

Summary

This proposed stock screen combines three technical conditions: a daily amplitude measure above 1, a positive weekly MACD condition described as a red histogram, and seven consecutive declining closes. The article frames the combination as a possible search for volatile shares that have sold off while weekly momentum remains positive, potentially identifying a short-term rebound setup. It includes sample indicator formulas and Python-style logic for applying the conditions.

The screen is only a candidate filter; it gives no backtest, returns, transaction rules, or evidence that a seven-day decline predicts a bounce. The author notes that consecutive declines can continue and that the rules omit company profitability, growth, and broader industry conditions. The code snippets also express the conditions differently in places, so the exact amplitude and consecutive-decline definitions should be checked before implementation. The article suggests adding other technical and fundamental checks, but provides no validation for those additions.

Key ideas

• The screen combines daily amplitude, positive weekly MACD, and seven consecutive declining closes.
• It is framed as a possible short-term rebound search after a sustained decline.
• The article provides sample formulas and code but no backtest or return evidence.
• A long sequence of falling closes does not guarantee an immediate rebound.
• Fundamental context and consistent definitions of the screening rules require further work.
