Using Volatility, Institutional Participation, and Large-Order Flows to Screen Stocks

Summary

This Chinese equity screening example proposes selecting stocks after the market opens using three conditions: a recent amplitude threshold, a change in estimated institutional participation, and positive large-order net flow. It frames amplitude as a measure of short-term movement, institutional participation as a clue about capital allocation, and net large-order flow as an indicator of buying versus selling pressure. The final rule translates these concepts into indicator thresholds.

The article acknowledges that the screen is narrow and omits macroeconomic, sector, and other company information. It also notes that large-order rankings are relative and open to interpretation, and recommends broader data coverage, additional indicators, and risk controls. A sample data workflow is supplied, but no backtest, trading results, or detailed validation is reported; the article does not establish that these flow measures predict returns. Definitions and data availability for the institutional and order-flow metrics may also vary across platforms.

Key ideas

• The screen combines recent price amplitude, a change in estimated institutional participation, and positive large-order net flow.
• The method is intended to identify active stocks with signs of buying interest.
• Large-order rankings are relative and may have more than one interpretation.
• The rules omit broader market, sector, and company fundamentals.
• The article gives no backtest or evidence that the indicators predict returns.
