Stock Screening with Turnover, Bid Depth, and Uptrend Filters

Summary

This stock-selection idea combines three filters: turnover between 3% and 12%, first-level bid volume greater than ask volume, and a condition described as the start of a major upward move. The article presents the bid-versus-ask comparison as a sign of buying pressure and uses moving-average and rising-price conditions in its example formulas and Python outline to represent an emerging uptrend.

The document offers formula references and a sample data workflow, but does not provide a backtest, measured returns, or evidence that the filters predict future performance. It warns that the trend-start condition can miss signals or trigger after a bull market has ended, and suggests adding indicators or sector filters as possible refinements. The code excerpt’s data fields and calculations should be checked against the actual data provider and intended definitions before use.

Key ideas

• The screen combines a turnover range, stronger best-bid volume than best-ask volume, and an upward-trend condition.
• The example represents trend strength with price and moving-average comparisons.
• The article supplies formula and Python references but no empirical performance results.
• The trend-start filter may miss moves or identify stocks after a market advance has peaked.
