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).

To upper EM = upper EM minus price (negative = trading above the band). To lower EM = price minus lower EM. Price = 5-minute bar close; time = bar start. H / L on the chart = RTH high / low. Grey dash-dot lines = EM range extended by 25% beyond each EM line. Shaded blue band = each bar's low-to-high range.
