Screening Chinese Stocks with Amplitude, Control, and KDJ Signals

Summary

This Chinese-language post proposes a stock screen combining price amplitude above a threshold, a daily control measure above a threshold, and a newly rising KDJ J line interpreted as a bullish crossover signal. It presents the conditions as a way to find volatile stocks with a technical buy indication. Indicator formulas and Python-style reference logic are included, along with a ranking calculation; the stated rule set is not accompanied by backtest results or measured returns.

The post cautions that technical indicators can produce false signals and may omit fundamental information. It suggests combining additional fundamental and technical measures, considering price-volume relationships, and accounting for trading costs. The “control” field’s precise definition and the robustness of the screening thresholds are not established in the text, so the screen should be treated as an illustrative hypothesis for further testing rather than a validated strategy.

Key ideas

• The proposed screen combines price amplitude, a daily control measure, and a rising KDJ J line.
• The KDJ condition is intended to identify a recent bullish technical signal.
• The post warns that KDJ can generate false signals and that technical screening omits fundamental information.
• It recommends combining other indicators and price-volume analysis, while accounting for trading costs.
• No backtest evidence or profitability results are provided, and the control measure is not fully defined.
