Intraday MACD and Bollinger Band Stock Screening

Summary

This Chinese stock-screening note proposes combining price range, Bollinger Bands, and a 15-minute MACD histogram for a rebound-oriented selection rule. Its stated logic looks for elevated price movement, a close in the lower portion of the Bollinger range, and a shrinking negative MACD histogram, which the author interprets as weakening short-term downside pressure. A formula example refines the range test relative to a recent average and places the close between the Bollinger midpoint and a discounted upper band; it also excludes a stock-code group.

The note offers no performance results or empirical validation. It flags false MACD signals, overreliance on correlated technical inputs, and omission of company fundamentals. It suggests adding fundamental and other factors and refreshing the selection rules as conditions change. The accompanying code examples are explicitly references and contain implementation inconsistencies, so the described conditions should be checked carefully before use. The method is a screening concept, not a demonstrated trading system.

Key ideas

• The screen combines price range, Bollinger Band location, and a 15-minute MACD histogram condition.
• A shorter negative MACD histogram is treated as evidence that near-term selling pressure may be easing.
• The formula example compares the price range with a recent average and constrains the close relative to Bollinger levels.
• The note warns that indicator false signals and narrow factor coverage can undermine the screen.
• No backtest or measured performance evidence is provided.
