- These figures describe past occurrences of the same shape. They are not a projection of this chart.
- 661 formations is not a large sample, and the instruments are correlated USDT pairs, so the effective sample is smaller still.
- Below 30 examples no rate is printed at all.
- Changes are close-to-close and exclude fees, funding and slippage.
- Medians and quartiles pooled across instruments are sample-weighted approximations, not exact pooled quantiles.
- A formation is timed from the bar its break became observable, and every change is measured strictly after that bar.
- Pooled across every instrument and both backtest timeframes.
