Screening Stocks for Intraday Declines and Lower Lows

Summary

This stock screen combines three daily price conditions: amplitude above 1, a stated daily decline between 4% and 5%, and a low below the previous session’s low. The accompanying explanation frames amplitude as a volatility filter and the lower low as a short-term price signal. It includes sample indicator logic and a Python example for applying the conditions across stock data.

The source offers no backtest or performance evidence, and its wording and examples leave some details uncertain. In particular, it describes a maximum decline while the sample code checks percentage change, and the amplitude and percentage-change scales may depend on the data convention used. The proposed screen focuses on short-term price behavior and may select stocks affected by broader market or sector declines. The document suggests adding fundamental, sentiment, industry, or trend filters and treating the lower low as one input among several; those ideas are suggestions rather than tested improvements.

Key ideas

• The screen selects stocks using amplitude, daily percentage change, and a lower low than the prior session.
• The explanation treats the conditions as short-term price and volatility filters.
• The sample implementation depends on consistent definitions and scales for amplitude and percentage change.
• The document provides no performance test and notes that fundamental or market context is absent.
