Chinese Stock Screen for Price Range and Afternoon Large-Order Inflows

Summary

This Chinese A-share screening idea selects stocks with an amplitude threshold, excludes stocks described as having hit the upper price limit on the prior day, and looks for afternoon net inflows attributed to large orders. The post frames the inflow condition as a sign of institutional buying interest and provides indicator and Python implementation examples.

The proposed interpretation is that large buyers may be accumulating shares, but the document supplies no tested evidence that this predicts continued gains. It cautions that the screen ignores company fundamentals and industry prospects, cannot ensure stable price behavior, and remains exposed to unusual market activity. The example code’s prior-day close comparisons and money-flow fields may not map cleanly to the prose description, and implementation details should be checked before use. The post recommends combining price and flow conditions with financial and industry analysis; it does not report backtest results.

Key ideas

• The screen combines price amplitude, a prior-day limit-up exclusion, and afternoon large-order net inflow.
• The post interprets large-order inflow as possible buying preference, without demonstrating predictive value.
• It warns that the screen omits company fundamentals and industry conditions.
• The provided implementation may not precisely match the written rule.
• No backtest performance or evidence of future returns is reported.
