Stock Screening with Intraday MACD Histogram Contraction and Activity Filters

Summary

This stock screen combines price activity and liquidity filters with a 15-minute MACD histogram condition. It selects stocks whose stated amplitude exceeds 1, whose previous-day trading amount exceeds 60 million, and whose MACD green bars are shortening. The article presents the approach as a way to focus on active stocks and includes sample indicator and data-processing logic using price history and MACD settings.

The provided code compares the current histogram value with its prior value, but that comparison does not unambiguously implement shortening green bars: the meaning depends on whether the histogram is positive or negative and on how bar color is assigned. The article supplies no backtest, forward-test, or return evidence, and acknowledges that market moves and policy changes can undermine the screen. It recommends adding other technical and fundamental data, but gives no entry, exit, or position-sizing rules.

Key ideas

• The screen combines an amplitude threshold, a previous-day trading-amount threshold, and a 15-minute MACD histogram condition.
• The article presents the filters as a way to find active stocks.
• The sample histogram comparison may not reliably represent shortening green bars across positive and negative values.
• The author notes that technical filters omit broader market and company conditions.
• No trading performance evidence or complete execution and risk rules are given.
