Chinese Stock Screening with Intraday Large-Order Flows and a Five-Day Average

Summary

This strategy screens Chinese stocks for daily price range above 1%, afternoon net inflows from large orders, and a closing price above the five-day moving average. It then proposes selecting the candidate with the highest gain. The document presents these conditions as a way to combine price volatility, trading flows, and short-term strength. It supplies indicator definitions and an example implementation, but no backtest results or evidence that the filters predict returns.

The author cautions that the rules emphasize technical signals and may overlook company fundamentals and longer-term prospects. Selecting the strongest recent performer can also expose traders to high valuations and speculative bubbles. Suggested refinements include adding valuation measures and filtering by market capitalization or industry. The example code has apparent inconsistencies in how it ranks candidates and applies conditions, so its implementation should be checked before use. The strategy’s results may depend heavily on market conditions and the exact definitions of its signals.

Key ideas

• The screen combines a daily range threshold, afternoon large-order inflows, and a close above the five-day moving average.
• It proposes choosing the strongest gainer among stocks that pass the filters.
• The document gives no performance test supporting the signals.
• Technical filters can miss company fundamentals and expose traders to overvaluation or speculative bubbles.
• Valuation, market capitalization, and industry filters are suggested as possible additions.
