Stock Screening with Turnover, Order Flow, and Weekly Gains

Summary

This stock screen combines turnover between 3% and 12%, an external-to-internal trading volume ratio above 1.3, and a positive weekly candle or weekly price change. The intended interpretation is that the turnover and order-flow conditions may indicate active buying, while a positive weekly signal adds a trend filter. The article provides a formula and a Python example that checks turnover, the ratio of external to internal volume, and the latest weekly close-to-close return.

The document does not report a backtest, a performance comparison, or evidence that these conditions reliably identify bottoming stocks or future gains. It acknowledges that market conditions change quickly and that technical filters may become unsuitable. It suggests testing additional indicators such as RSI or MACD and considering financial data, but gives no results for those extensions. The formula and implementation are not fully aligned in their expression of the conditions, so the exact data definitions and calculation rules would need to be checked before interpreting the screen or reproducing it.

Key ideas

• The screen combines turnover of 3%–12%, an external-to-internal volume ratio above 1.3, and a positive weekly signal.
• The proposed rationale is to combine trading activity with a weekly trend confirmation.
• The article includes both an indicator formula and a Python example, but their condition expressions are not fully consistent.
• No backtest or evidence of predictive performance is provided, and the document notes that market conditions change.
