Relative-Volume Opening Range Breakouts in U.S. Stocks

Summary

This article explains an intraday opening range breakout strategy for U.S. equities. It selects liquid stocks with elevated activity shortly after the open, on the premise that corporate news can prompt institutional repositioning and create directional moves that continue through the session. Relative volume compares opening-range volume with its average over recent sessions; the strategy ranks active stocks and trades the strongest candidates. A preliminary screen excludes low-priced or less liquid stocks using price, average volume, and average true range criteria.

The article cites Swiss Finance Institute research covering more than 7,000 stocks from 2016 to 2023. It reports that applying a relative-volume filter and selecting a small portfolio increased reported returns substantially, while the strategy had a low win rate but favorable risk-reward. These results describe the cited study and do not establish future performance. The implementation discussion focuses on aligning broker time with the New York session, triggering scans with a timer at the opening range close, and closing positions at the session end. Time-zone handling and the article's stated limitations around testing and deployment matter when interpreting the approach.

Key ideas

• The strategy treats unusual opening volume as evidence of a possible supply-demand imbalance linked to corporate news.
• Relative volume compares current opening-range activity with its recent historical average.
• A liquidity and volatility pre-screen helps remove unsuitable stocks before ranking daily candidates.
• The system enters after the opening range and closes positions by the end of the session.
• The cited backtest results are historical evidence, not a guarantee of future profitability.
