VWAP Stretch
Price has run so far from VWAP that chasing the move is poor location — the Institutional Checklist treats it as a reason to wait.
A VWAP Stretch is when SPX trades far away from VWAP — the session's volume-weighted fair price. The further price runs from fair value, the worse the location for a new trade in the same direction, and the more likely a pullback toward VWAP before anything else.
How SPXXL measures it: the Institutional Checklist flags a stretch when price is 2 or more standard deviations from VWAP. When the deviation band is not available, it falls back to 3× the average bar range.
Why it matters: a stretched market can keep going, but entering there means your stop is far away and your reward is small. The checklist marks the VWAP check as not passed, so the answer becomes Wait instead of Go.
For 0DTE traders: let the stretch come back toward VWAP, then re-read the checklist. Chasing a stretched move with a debit spread means paying up for poor location.
