                "text": "It's a count, not a guess. The indicator takes the last ninety days of net price moves at each hour slot, then measures how much those moves typically vary from their average. One sigma (\u00b11\u03c3) covers about sixty-eight percent of those historical moves; two sigma (\u00b12\u03c3) covers about ninety-five percent. When price sits near the \u00b11\u03c3 band, it's doing what the last ninety days said it would. When it pokes through \u00b12\u03c3, it's in the outer five percent of how this instrument behaves at this hour.",

                "text": "Every night at the session rollover (18:00 ET), the lookback window slides one day forward. Yesterday's data gets added, day ninety-one drops off, and a fresh \u03c3 gets computed for every slot. That's why the bands quietly widen in high-volatility regimes and contract in quiet ones \u2014 you don't have to re-tune anything, and the levels never reflect a market that no longer exists. You can set the lookback anywhere from 1 to 365 days in settings.",

The 22:00\u201302:00 ET Asia block and the 09:30\u201310:30 ET US open have completely different volatility footprints \u2014 using one number for both overstates overnight and understates the cash open. The indicator keeps twenty-four hourly slots and six 4-hour slots so each band reflects the clock time it's projected from. Daily (D1) uses one slot, because by definition a day is a day.",

These bands anchor to the session open and stay put for the duration of the session, so alerts, stops, and targets can be planted at a specific price. Bollingers also use one \u03c3 across all hours; this indicator has thirty-one distinct \u03c3 values (24 H1 + 6 H4 + 1 D1). Different tool, different job.",
