Stock Screening with Opening Range, Ten-Day Average, and Large-Flow Buying

Summary

This Chinese-language article outlines an equity screening rule that combines three conditions: prior-session amplitude above a threshold, the opening price near the ten-day moving average, and positive net buying attributed to large investors during the opening auction. The accompanying examples operationalize “near” as within five percent of the moving average, calculate amplitude from the previous session’s high, low, and close, and rank qualifying names by volume. The stated rationale is to find volatile stocks opening around a short-term average with buying support, potentially during a rebound.

The article warns that the screen omits broader fundamentals, reflects only one category of investor flow, and may mislead in choppy markets. It suggests adding financial data, combining flow measures, and defining trade and risk controls. No backtest, return series, or quantified evidence is presented, and the examples rely on platform-specific data fields. The rule is therefore a screening concept, not evidence of a profitable strategy.

Key ideas

• The screen combines prior-session amplitude, opening price near the ten-day average, and positive auction net buying by large investors.
• The example defines proximity to the moving average as a five-percent band.
• Qualifying stocks are ranked by trading volume in the provided example.
• The article flags omitted fundamentals, incomplete investor-flow coverage, and possible errors in sideways markets.
• It recommends additional factors and explicit trading and risk rules, but reports no performance testing.
