Screening for Rounded Price Patterns and Non-Limit-Up Stocks

Summary

This Chinese equity screen combines price amplitude above 1, a rounded price shape, and a requirement that the previous session was not a limit-up day. The accompanying indicator expression also imposes conditions involving a 60-session price range relative to a 30-session range, a minimum stock age, the trading session, and a recent overnight-existence check. The article describes the rounded pattern as a way to find more gradual price movement and treats avoiding a prior limit-up as a way to reduce exposure to stocks that may already be overbought.

No Python implementation is supplied, and the article provides no backtest, candidate examples, or performance measurements. It acknowledges that these technical filters cannot capture company fundamentals or changing market conditions, and that the shape and amplitude rules may misclassify price behavior. It recommends broader research and additional filters, but does not define those rules or demonstrate that they improve results. The screen is best understood as a preliminary selection recipe, not a tested trading system.

Key ideas

• The screen combines amplitude above 1, a rounded price shape, and no limit-up session on the previous day.
• Its formula compares price ranges over 60 and 30 sessions and includes additional stock-age and timing conditions.
• The author presents gradual price movement as a possible way to avoid sharper volatility.
• The article supplies no Python implementation or evidence from a backtest.
• Technical filters alone may miss fundamental changes and can classify price patterns incorrectly.
