Chinese Stock Screen Combining KDJ Crossovers and Recent Price Surges
Summary
The article describes a Chinese stock screen requiring daily amplitude above 1, a newly formed KDJ golden cross, and at least one daily rise of 10% or more during the prior 25 trading days. It interprets the range condition as evidence of volatility, the crossover as a possible improvement in sentiment, and the recent surge as a sign of strength. Formula and Python examples show calculations for the indicators and candidate selection.
The author notes that technical filters can overlook company fundamentals, introduce selection bias, and expose traders to short-term risk after a strong move. Suggested additions include valuation measures, other indicators, fund-flow information, and adapting the screen to market conditions. No backtest, returns, or comparison is supplied, so the stated interpretations are hypotheses rather than demonstrated predictive results. The examples also use particular crossover, price-change, and indicator calculations; these definitions and the time alignment should be checked against the intended rule before relying on a signal.
