Stock Screening with Moving Average Convergence, Bollinger Bands, and Trend

Summary

This stock-screening proposal combines three conditions: at least five moving averages are said to converge, the close is intended to lie between the Bollinger middle and upper bands, and the 30-day moving average should be rising. The post presents the combination as a buy signal, with moving-average convergence representing stability and the rising average representing a positive intermediate trend. It also suggests varying the number of averages or Bollinger parameters and adding volume or other indicators.

There is no backtest or empirical evidence supporting the signal, and the written explanation conflicts with itself: it describes the close as both above the upper band and below the middle band in one passage. The included code also checks equality among consecutive closes as a proxy for moving-average convergence, which is not the stated condition. The post says the rules identify entries but do not define exits or determine fair price, so the idea remains incomplete and needs careful specification before evaluation.

Key ideas

• The proposed screen combines moving-average convergence, Bollinger band position, and an upward 30-day average.
• The intended price condition is a close between the middle and upper Bollinger bands.
• The written explanation and sample code contain mismatches in the conditions they describe.
• The proposal provides no performance evidence and does not define exit rules.
