Screening Chinese Stocks with Turnover, Order Flow, and a KDJ Pattern

Summary

This Chinese-language strategy note proposes screening stocks using turnover between 3% and 12%, an external-to-internal trading volume ratio above 1.3, and a pattern described as a morning star in the KDJ indicator. It interprets turnover and the volume ratio as signs of trading activity or buying pressure, and presents the KDJ condition as a possible signal of a short-term price reversal. The article includes example screening logic and Python-style pseudocode, although the code uses stochastic calculations and comparisons that may not exactly match the prose description.

The note gives no backtest, sample definition, transaction costs, or performance results, so it does not establish that the screen predicts returns. It also acknowledges that price and trading-activity filters can miss other attractive stocks and be vulnerable to market fluctuations. Suggested extensions include adding financial or fundamental variables and other technical measures, but no tested optimization is supplied. The stated thresholds and signal should therefore be treated as a proposed selection rule rather than validated evidence.

Key ideas

• The proposed screen combines turnover in a stated range with an external-to-internal volume ratio above 1.3.
• It adds a KDJ-based pattern intended to identify a possible short-term reversal.
• The article provides example formula logic and pseudocode, but their signal definitions may differ in detail.
• No backtest or return evidence is provided to validate the selection rule.
• The author notes that market volatility and omitted fundamental information may limit the screen.
