Intraday Chinese Stock Selection Using Reversal and Limit-Up Signals

Summary

This proposed Chinese equity screen looks for stocks before 10 a.m. with daily high-to-low amplitude above 1%, a reversal or engulfing-style pattern, and no ST risk warning designation. It also requires a five-session limit-up signal. The article presents both indicator-formula and Python examples, describing the idea as a way to identify volatile stocks showing short-term directional movement. The Python sketch uses price history, an ST flag, a candlestick pattern function, and a derived limit-up condition to assemble candidates.

The document provides no backtest results or evidence that the screen predicts future returns. It warns that limit-up stocks can face trading halts and that the filters may exclude opportunities; it suggests considering sentiment and fundamentals as additional context. The implementation details also leave ambiguities: the text does not fully define the “five-step” limit-up condition, and the code's signal construction is not clearly reconciled with the stated amplitude threshold. Any evaluation would need precise rules, survivorship-aware data, and realistic assumptions about intraday access and execution.

Key ideas

• The screen combines price amplitude, a reversal pattern, exclusion of ST-designated stocks, and a pre-10 a.m. selection time.
• A five-session limit-up condition is included as a further momentum filter.
• The article supplies formula and Python sketches but does not report a backtest or realized performance.
• Limit-up trading may involve halts, and the signal definitions and code require clarification before evaluation.
