A-Share Rebound Screen Using High Amplitude and Three Down Days

Summary

This document outlines a Chinese stock screen seeking shares with amplitude above 1, no limit-up session on the prior day, and three consecutive down days. The proposed idea is that a recent run of losses may create a rebound opportunity, with price amplitude used to focus on stocks that have moved more substantially. It provides a formula for amplitude based on the day's high and low relative to the previous close, plus example selection code.

The article notes that the method focuses on falling prices and does not include company fundamentals, so results may be exposed to market volatility and weak underlying businesses. It suggests combining additional technical measures and fundamental data. No backtest results or evidence that the pattern predicts rebounds are presented. The sample code's handling of limit-price lists and rolling price conditions may not faithfully implement the full prose rule, so the described setup is best read as a screening concept rather than a validated strategy.

Key ideas

• The proposed screen combines amplitude above 1, a prior session that was not limit-up, and three consecutive declining sessions.
• The rebound thesis assumes that a sequence of losses may precede a recovery.
• The method is based on price action and omits fundamental company analysis.
• The document offers no backtest evidence, and the sample code may not match every stated condition.
