Chinese Stock Screen Combining Large-Order Flows and a Rising 30-Day Average

Summary

The described Chinese stock screen combines three ideas: positive large-order net volume for at least three consecutive days, a daily position-increase ratio above 5%, and an upward-sloping 30-day moving average. The narrative treats persistent large-order buying and increased positions as signs of inflows, with the moving average used to represent the broader trend. It proposes further filters such as volume and turnover, along with technical indicators, as possible refinements.

The post provides no backtest, performance figures, or evidence that these signals forecast returns, and it notes market-wide and company-specific risks. Its sample implementation does not clearly match the stated rules: it compares flow and turnover with rolling averages and tests a one-day close change, while its moving-average condition compares the 30-day average with the current close. This discrepancy makes the code an uncertain representation of the prose. The post also leaves execution, exit timing, and position sizing unspecified.

Key ideas

• The narrative requires large-order net volume above 0.05 for at least three days and a daily position-increase ratio above 5%.
• It also describes a rising 30-day average as a trend filter.
• The sample code appears to implement conditions differently from the written criteria.
• No backtest or performance evidence is provided.
• Market and company-specific risks remain, while execution and exit rules are unspecified.
