Mainland China Stock Screen Using Turnover and Large-Order Flow

Summary

This stock-screening idea selects Shanghai-listed shares whose codes begin with 60, whose turnover rate falls between 3% and 12%, and whose large-order net flow remains above 0.05 for at least three consecutive days. The stated rationale is that positive large-order flow may indicate institutional buying. The document includes a Python example that retrieves stock listings and money-flow data, then checks for repeated positive readings.

The post offers a screening rule, not a complete trading strategy: it does not specify entry timing, exits, position sizing, or portfolio controls. It warns that market volatility can affect results and that large-order flow calculations may be inaccurate, so the metric is not definitive evidence of institutional demand. No backtest, benchmark, or performance statistics are provided. It suggests combining the screen with other indicators or multiple timeframes, but does not evaluate those additions. The code's data fields and date window should also be checked against the intended interpretation of the rule before use.

Key ideas

• The screen filters shares with codes beginning with 60 and turnover between 3% and 12%.
• It requires large-order net flow above 0.05 for at least three consecutive days.
• The post treats positive large-order flow as a possible clue to institutional buying, not conclusive proof.
• It gives no backtest or complete entry, exit, or portfolio management plan.
