Chinese Stock Screen Using Intraday Inflows, Range, Volume, and Gap-Up

Summary

This stock-selection screen combines four conditions: daily amplitude above a threshold, afternoon large-order net inflow, current volume above a threshold, and a gap-up open. The post describes amplitude and inflow as measures of price movement and incoming buying interest, while volume is intended to indicate trading activity. Stocks passing the filters are treated as candidates for further review.

The document supplies indicator formulas and example code, but does not provide backtest results or evidence that the filters predict returns. It cautions that a purely technical screen can overlook company fundamentals and that gap-up signals can be affected by market sentiment. Suggested refinements include adding valuation measures such as price-to-earnings or price-to-book, along with turnover and traded value, then applying fundamental and macroeconomic filters. It also recommends risk controls such as profit-taking and stop-loss rules, without specifying how to set them.

Key ideas

• The screen selects stocks using price amplitude, afternoon large-order inflow, trading volume, and a gap-up open.
• The stated thresholds are screening criteria, not evidence of profitable performance.
• The post warns that technical filters can omit fundamental information and may be sensitive to sentiment.
• It suggests adding valuation, turnover, traded-value, and macroeconomic checks.
• Risk controls are recommended, but their parameters are not specified.
