Chinese Stock Screen Using Intraday Range, Large-Order Flow, and Prior Low

Summary

This Chinese equity screening idea selects stocks with a daily range above 1%, a high large-order net-volume measure, and a close above the previous session’s low. The page presents these as short- to medium-term technical filters, shows a formula reference, and includes a Python sketch that sorts qualifying names by turnover. Its code uses a threshold of 0.8 for the large-order measure, although the prose describes this criterion as a ranking and does not clearly explain the measure’s construction.

The document offers no backtest, sample size, benchmark, or reported trading results. It warns that technical indicators alone cannot account for market uncertainty and recommends considering fundamentals and broad market conditions alongside other technical measures. The examples also leave implementation questions: the code appears to retrieve one stock’s daily data and references prior rows by index, so it does not clearly establish a robust cross-sectional ranking process. The selection rule should be treated as a rough screening template, not as evidence of an effective strategy.

Key ideas

• The screen combines a daily price range above 1%, a large-order net-flow threshold, and a close above the prior low.
• The example code sorts the selected stocks by turnover rate.
• The article recommends supplementing technical filters with company fundamentals and overall market context.
• No performance data is provided, and the meaning and implementation of the large-order ranking are not fully specified.
