Screening Stocks by Amplitude, Rounded Price Shape, and Short Lookback

Summary

This Chinese stock-screening proposal combines daily amplitude above 1, a rounded price pattern, and a condition using a lookback shorter than 20 bars. The accompanying formula operationalizes the shape with recent highs and lows and includes a count of bars since a prior price rise. The rationale is to find stocks with movement that may offer short-term opportunities while using the rounded pattern as a potentially smoother setup.

The document acknowledges that the rounded-shape concept is subjective and that the screen may miss larger companies. It suggests standardizing the pattern definition and adding industry, fundamental, or algorithmic inputs, but provides no Python implementation, backtest, or performance evidence. The formula’s conditions are not fully reconciled with the brief verbal description, so implementation details and the meaning of “rounded” require careful review before use.

Key ideas

• The proposed screen uses amplitude above 1, a rounded price pattern, and a short bar-count condition.
• The formula approximates the pattern using recent price highs, lows, and bar history.
• The author identifies subjectivity and operational uncertainty in interpreting the shape.
• No backtest results or working Python example are provided.
