Classifying Markets with Previous-Day High and Low Breaks

Summary

This brief strategy proposes using breaks of the prior bar’s range to gauge whether an instrument may be trending or mean reverting. It enters long when the close rises above the previous bar’s high and reverses to short when the close falls below the previous bar’s low. The rules repeatedly switch direction as the close crosses these levels.

The suggested diagnostic is the resulting equity curve: an upward curve is interpreted as evidence of trend behavior, while a downward curve is taken to suggest mean reversion. The document provides this as a simple heuristic, not as a demonstrated empirical result; it gives no instrument, test period, performance statistics, or transaction-cost assumptions. Its usefulness therefore depends on careful testing across markets and regimes, since one strategy’s profitability alone cannot establish a general market classification.

Key ideas

• A close above the previous bar’s high triggers a long entry.
• A close below the previous bar’s low reverses the position to short.
• The strategy uses its equity-curve direction as a heuristic for classifying trend-following versus mean-reverting behavior.
• No backtest results or market-specific evidence are provided.
