Short-Term Stock Screen Using Price Range, Two-Day Highs, and Volume

Summary

This post proposes a short-term stock screen based on three conditions: intraday amplitude above 1%, a current high equal to the highest high over two days, and a condition described as yesterday’s turnover exceeding 8%. It gives formula-style examples for calculating amplitude from the high, low, and prior close, and for checking the two-day high. Its sample code and prose do not align cleanly on the turnover condition: the formula examples compare volume with prior volume, while the stated rule refers to turnover rate. That distinction would need to be resolved before implementation.

The author presents the combination as a way to find active stocks showing recent strength, but supplies no backtest, return data, or execution rules. The post notes that high activity may not indicate durable investor interest and that the screen ignores company fundamentals such as profitability, asset quality, and growth. It suggests adding fundamental and technical filters, but does not specify or evaluate them, so the proposal remains an incomplete screening idea rather than a validated strategy.

Key ideas

• The proposed screen combines amplitude above 1%, a two-day high, and a stated turnover condition above 8%.
• The example defines amplitude using the day’s high and low relative to the previous close.
• The turnover rule is ambiguous because the examples refer to volume relative to prior volume rather than turnover rate.
• The post says the screen omits company fundamentals and suggests adding fundamental and technical measures.
• No backtest or performance evidence is provided.
