Screening Chinese Stocks with Turnover, KDJ, and Large-Order Flow

Summary

This stock-selection screen combines a turnover range of 3% to 12%, a rising KDJ K value, and a condition relating the daily price return to net volume attributed to very large orders. The proposed rationale is to favor shares with active trading, improving short-term momentum, and supportive large-order flow. The document gives a Tongdaxin-style screening expression and a Python sketch that groups observations by stock and applies similar filters.

The source offers a rule description and code examples, but no backtest, benchmark, or performance evidence. Its implementations are not fully aligned: the narrative compares the return-flow product with an average, while the Python expression applies a different-looking comparison, and the handling of the flow measure is not clearly specified. The author also notes that the screen omits company fundamentals and industry context, and that reliance on large-order flow can be risky. The proposed additions, such as volume, MACD, and fundamental or industry analysis, are suggestions rather than validated improvements.

Key ideas

• The screen requires turnover between 3% and 12% and a rising KDJ K reading.
• It combines price change with net volume from very large orders as a flow-related filter.
• The document provides formula and Python examples but no reported performance test.
• The examples appear to operationalize the return-flow comparison differently, so exact replication requires resolving that ambiguity.
• The author cautions that market-flow signals omit fundamentals and industry conditions.
