Stock Screening with Turnover, Reversal Patterns, and Large-Order Inflows

Summary

This stock-selection idea filters for turnover between the stated lower and upper bounds, a pattern described as a reversal or engulfing move, and positive net large-order inflow in the afternoon. The article presents these conditions as a way to combine trading activity, price behavior, and capital flow. Its sample calculation approximates a reversal condition using the position of the previous close within the day’s high-low range, then checks net large-order inflow.

The author notes that the screen omits fundamentals such as company size and profitability, and that the afternoon period used for fund-flow data is not clearly defined. Adding fundamental, technical, and volume-price measures is suggested. No backtest or return evidence is provided, and the sample code’s data joins and timing do not establish that it faithfully implements the stated intraday filter. The conditions therefore describe a screening hypothesis rather than a validated buy strategy.

Key ideas

• The screen combines a bounded turnover range, a reversal-style price condition, and positive large-order net inflow.
• The sample reversal proxy uses the prior close’s location within the day’s high-low range.
• The article identifies omitted fundamental factors and ambiguity in the afternoon flow window.
• No performance evidence is provided, and the sample implementation may not match the stated intraday logic.
