Intraday Stock Screening with Range, Rounded Price Action, and Opening Gain

Summary

This stock screen combines three conditions: daily amplitude above one, a rounded price shape, and a 9:25 a.m. gain below six percent. The accompanying indicator formula approximates the rounded shape by comparing the prior close with the five-bar high and low range. The article interprets the range filter as a way to find active stocks without excessive fluctuation, the rounded shape as a sign of smoother movement, and the opening-gain cap as a way to avoid stocks that have already risen sharply before entry.

The post provides no backtest, performance figures, or evidence that these conditions predict returns. It cautions that the 9:25 price move can be random and that focusing on it can leave out technical, fundamental, or premarket news factors. It recommends combining the screen with additional indicators and company information. The rule is therefore a selection heuristic, not a validated trading system; its usefulness depends on precise definitions, data timing, and further testing.

Key ideas

• The screen requires amplitude above one, a rounded price configuration, and a 9:25 a.m. gain below six percent.
• The rounded shape is represented by the position of the prior close within a five-bar price range.
• The post presents smoother movement and a restrained opening gain as possible screening benefits.
• It provides no performance evidence and warns that the opening move may be random.
• Additional technical, fundamental, and premarket information could supplement the criteria.
