Chinese Stock Screen Using Price Range and Large-Order Flows

Summary

This Chinese equity screen selects stocks with an amplitude above 1, an indicated 9:25 price gain below 6%, and positive large-order net flow for at least three consecutive days. The post describes using these conditions to form a candidate pool, followed by additional fundamental and technical review. It also gives examples of indicator and Python implementations, though their calculations do not consistently match the stated thresholds or definitions.

The author says order-flow conditions may reflect changing capital flows, but warns that sentiment and herding can affect results. The strict flow filter may produce few candidates, which could still carry substantial risk. Suggested refinements include adding price-volume and moving-average analysis, applying further fundamental filters, and setting trading and loss-control rules. No backtest or performance evidence is provided, so the screen's effectiveness is not demonstrated.

Key ideas

• The screen combines price amplitude, a 9:25 price-change limit, and consecutive days of positive large-order net flow.
• The article proposes further fundamental and technical review after building the initial stock pool.
• Market sentiment and capital flows may make the selected stocks vulnerable to herding and excessive price chasing.
• The examples contain implementation details that do not fully align with the prose description.
• The post provides no backtest results to establish whether the rules are profitable.
