Use the Alligator values visible at the decision bar
A positive plot offset moves a previously calculated value to a later chart position; it does not provide future data. At bar t, the plotted Jaw corresponds to its 13-period smoothed midpoint value from t − 8, Teeth to its 8-period value from t − 5, and Lips to its 5-period value from t − 3.
Comparing the current, unshifted averages is another valid rule, but it will not reproduce the displayed line ordering. Choose one convention and use it consistently for filters, exits and chart checks. Wait until all required historical values are available.
