A-Share Screen Using Daily Range, Large-Order Flow, and the 250-Day Average

Summary

This document describes a Chinese equity screen that combines daily amplitude above 1%, a large-order net-flow ranking, and a prior close above the 250-day moving average. It presents the combination as a way to select volatile stocks with a longer-term upward price trend and includes sample indicator and Python implementations. The examples sort candidates by turnover, but the code has data and indexing assumptions that are not explained, and it does not provide a reproducible complete test.

The article warns that technical filters alone can miss company performance and broad market conditions, leaving the selection vulnerable during market-wide declines. It recommends incorporating financial measures, industry developments, policy context, and overall market conditions. No backtest or empirical performance evidence is supplied. The screen therefore describes a candidate-ranking approach, not a demonstrated source of returns, and the meaning and calculation of the large-order flow threshold are left unclear.

Key ideas

• The screen combines daily amplitude above 1%, large-order net-flow ranking, and a close above the 250-day moving average.
• The moving-average condition selects stocks trading above a long-term trend reference.
• The article cautions that technical signals omit fundamentals and broad market risk.
• The code and flow metric are insufficiently specified, and the document reports no backtest results.
