Stock Screening with a Rising 30-Day Average, Price, and Range Filters

Summary

This post describes a simple equity screen using three conditions: a closing price below 12, daily high-low range above 1% of the previous close, and a 30-day moving average that rose from the prior day. The stated rationale is to combine comparatively low share prices and active trading ranges with a positive short-term trend. It gives indicator formulas and an example of combining the filters, with an additional ranking field left unspecified.

The post notes possible data errors and timing lag from relying on a rising moving average, and recommends risk controls such as stop levels. It also proposes adding technical and fundamental checks, including momentum or valuation measures. These are suggestions rather than a tested refinement: the document provides no backtest, sample results, or evidence that low nominal price and a one-day average increase predict returns. The screen is therefore a starting specification whose market, data, and execution assumptions require evaluation.

Key ideas

• The screen requires a closing price below 12 and a daily range exceeding 1% of the previous close.
• A rising 30-day moving average serves as the trend condition.
• The document supplies formulas for the range, price, and moving-average filters.
• It identifies data errors and delayed signals as risks of this approach.
• It recommends additional analysis and risk controls but reports no performance testing.
