Stock Screening with Reversal Patterns, Daily Range, and Recent Limit-Ups

Summary

This Chinese equities screen looks for stocks with a daily high-to-low range above one percent, a reversal or engulfing-style pattern, and at least one limit-up event within the prior 25 days. The post frames the range as a volatility filter, the reversal pattern as a possible change in short-term price direction, and a recent limit-up as evidence of strong momentum. Its refined description specifies that the reversal should have appeared within the last three days.

The article includes indicator formulas and a Python example, but the implementations are not fully consistent with the written criteria. It specifically notes that the limit-up condition is difficult to reproduce in the sample environment and substitutes a candle-pattern proxy, which may identify different events. No backtest statistics or performance evidence are supplied. The post characterizes the method as chasing recent strength and warns that it relies on market behavior while largely ignoring fundamentals and broader market risk. It suggests combining the signals with volume, moving averages, and fundamental measures, without evaluating those additions.

Key ideas

• The screen combines a daily range above one percent, a reversal pattern, and a limit-up event in the previous 25 days.
• The refined rules specify a reversal pattern within the latest three days.
• The Python example approximates limit-up events with candle patterns, so results may differ from the intended rule.
• The strategy targets recent strength and may carry momentum-chasing and market risks.
• No backtest results are provided, and fundamentals are largely omitted.
