Counted from the 9:30 open until the 11:00 ET entry cutoff (touches after it are not shown): a touch = a bar reaches the 75% / 25% zone line. After the first, a new touch counts only when price reaches the opposite zone (same rule as the hub's Round Trip Dashboard).

Grey dash-dot lines = EM range extended by 25% beyond each EM line. Shaded blue band = each bar's low-to-high range.
