How to read the EZA numbers

The strongest configuration was the 5-minute long break: 62% winners across 124 trades. The long side carried the edge overall: 61% winners versus 54% for the other direction. After wins and losses netted out, 6 of the 6 configurations carried positive expectancy per trade.

Backtest method

Entry is the break of the opening range: above the range high for longs, below the range low for shorts. The target projects one full range width from the break and the stop sits at the opposite side of the range, so risk and reward are both defined by the range itself. The window is the last 730 calendar days ending August 7, 2026, every qualifying trade counted, with no commissions or slippage modeled.

This is a historical record, not a prediction. Win rates drift as volatility regimes change, and a strong two-year record on $EZA does not guarantee the next break follows it. Use it as context for sizing and expectations, not as a signal.
