Screening for Rounded Price Patterns, Amplitude, and Listing History

Summary

This Chinese A-share screening concept combines price amplitude above 1, a rounded or arc-like price pattern, and a minimum listing age. The article describes the rounded pattern as a way to favor smoother price behavior and suggests that longer-listed companies may have more established fundamentals and market recognition. It includes a technical-indicator formula that appears to approximate a rounded pattern using comparisons between recent price ranges, alongside listing-age and other timing conditions; no Python implementation is supplied.

The author acknowledges that these filters alone do not capture company fundamentals or changing market conditions, and that a long listing history does not guarantee good business performance. The article recommends combining technical and fundamental research and adjusting criteria as conditions change. It provides no definitions for the pattern beyond the formula, nor any backtest or return evidence, so the screening rationale remains unvalidated.

Key ideas

• The screen combines amplitude, a rounded price pattern, and listing age.
• The formula approximates the rounded pattern through comparisons of recent price ranges.
• The article treats listing history as context rather than proof of business quality.
• It recommends combining technical filters with fundamental research and adapting the criteria.
• No backtest or performance evidence is included.
