Stock Screening with Intraday Range, the 10-Day Average, and Bid–Ask Volume

Summary

This stock screen combines three conditions: the prior bar’s high-low range must exceed one percent of its close, the opening price must lie within five percent of the 10-day moving average, and first-level buy volume must exceed sell volume. The article frames these filters as a way to find shares with recent movement, an open near a short-term average, and stronger displayed buying interest. It also shows example implementations in formula-style syntax and Python, then suggests sorting qualifying names by volume.

The document offers a screening recipe rather than a tested trading system. It provides no backtest, return statistics, holding rules, or transaction-cost analysis, and it does not define how the order-book volume fields are sourced or timed. The author cautions that technical filters alone can select weak companies and recommends considering fundamentals and limiting position sizes with loss controls. The stated thresholds and interpretations should be independently evaluated before use.

Key ideas

• The screen requires a prior-bar range above one percent of the prior close.
• It accepts openings within five percent of the 10-day moving average.
• It filters for first-level buy volume greater than sell volume.
• Qualifying stocks are suggested to be ranked by volume.
• The article supplies no evidence that the screen is profitable.
