Chinese Stock Screening with Positive Large-Order Flow and Opening Gains

Summary

This note proposes screening Chinese equities for positive large-order net flow over at least three consecutive days, a 9:25 a.m. gain below 6%, and today’s position increase above 5%. It frames the flow measure as a sign of trading activity and the opening-gain cap as a way to avoid stocks that may have risen sharply before the session. The sample selection logic refers to recent volume, price, and buy data, but it does not clearly define those fields or show how their thresholds correspond to the headline conditions.

The author identifies important gaps: the screen omits company finances and industry prospects, and short-term price swings could produce misleading selections. Suggested extensions include adding financial and industry factors or technical indicators. The note gives no backtest, performance results, or precise data definitions, and its code-like example is too ambiguous to establish a reproducible rule. It therefore offers a rough screening concept rather than evidence that the conditions predict returns.

Key ideas

• The proposed screen combines positive large-order net flow over three or more days with an opening gain below 6% and a position-increase condition above 5%.
• The author treats large-order flow as an indicator of trading activity.
• Company fundamentals and industry conditions are absent from the stated selection logic.
• The example does not clearly define its data fields or map them to the stated thresholds.
• No backtest or performance evidence is provided.
