Screening Stocks by Intraday Order Flow and Opening Price Change
Summary
This screen selects stocks using three intraday market-behavior conditions: an increase in the day’s position-building share above 5%, net buying by large orders in the afternoon, and a price rise below 6% at 9:25. The article interprets the first two as signs of capital inflow and treats the opening-price condition as a way to avoid stocks with a larger early rise. It advises considering the conditions together with other evidence rather than treating any one signal as decisive.
The document offers a qualitative explanation but no precise definitions of the order-flow measures, data source details, trading rules, backtest, or performance results. It cautions that market sentiment and company news can affect these signals, and that relying on them alone may lead investors to miss other important factors. Suggested additions include valuation ratios and trend or moving-average analysis. Because the measures’ calculation and timing are unspecified, the screen’s reproducibility and practical usefulness depend on clarifying those details and testing the rules against suitable historical data.
