Screening Chinese A-Shares by Range and Large-Order Net Flow

Summary

This stock screening idea selects shares with a daily price range above one, large-order net volume above 0.05 for at least three consecutive days, and excludes Beijing-listed A-shares. The article presents the conditions as a way to find active market themes and potential opportunities. Its accompanying Python example calculates a range from high, low, and prior close, sums net volume over a rolling three-day window, and filters securities by code prefix.

The article warns that relying on technical measures and market themes may overlook financial fundamentals and longer-term prospects. It also notes that excluding a region is a crude way to account for policy risk. No backtest, returns, or validation of the screening thresholds are reported. The sample code’s range filtering and regional exclusion should be checked against the stated logic and the relevant market’s listing codes before use; the article itself recommends combining technical, fundamental, and policy considerations.

Key ideas

• The screen requires daily range above one and large-order net volume above 0.05 for three or more consecutive days.
• It excludes Beijing A-shares as a regional filter.
• The example uses a rolling three-day sum for net volume and derives a range from daily price data.
• The article cautions that technical and flow criteria can neglect fundamentals and long-term prospects.
• It provides no performance evidence, and the code’s conditions merit validation before use.
