Chinese Stock Screening with Turnover, Reversal, and Bid-Side Volume

Summary

The proposed Chinese equity screen selects stocks with turnover between 3% and 12%, a reversal pattern described as an engulfing move, and first-level bid volume greater than first-level ask volume. The article frames turnover and reversal as signs of favorable price behavior, while the order-book comparison is intended to indicate stronger buying interest. It includes example screening expressions and a Python workflow that combines daily turnover data, money-flow fields, closing prices, and stock reference data, then sorts candidates by market capitalization.

The article cautions that the screen ignores company fundamentals and valuation, potentially selecting overvalued firms or missing quality companies. It also notes that displayed bid and ask data can be unreliable. The sample Python workflow does not clearly implement every stated criterion: it does not visibly apply the turnover bounds or the reversal condition, and it compares aggregated small-order volume fields rather than first-level order-book quantities. No backtest results or evidence of predictive performance are provided.

Key ideas

• The screen combines a specified turnover band, a reversal pattern, and stronger bid-side than ask-side volume.
• The proposed logic is presented as a candidate selection filter rather than a complete portfolio strategy.
• The article provides example platform logic and a data-merging workflow for stock screening.
• It warns that fundamental quality and valuation are omitted and that order-flow data can be misleading.
• The example Python workflow does not visibly implement all stated screen conditions.
