Click refresh to pull the latest Massive I:SPX print, or type a historical day/time to replay the dashboard as-of that bar. The server rebuilds the Saty ATR ladder from prior-close + prior ATR, calculates PO / pivot ribbon values, then maps the session against the SPX ATR Cascade and Open-Band Path studies.
Public levels are from the SPX ATR Cascade ladder. Outer ±2.236 rails are calculated for awareness but not part of open-band cohorts.
First-hit sequence excludes levels already beyond the opening print, matching the cascade study convention. Historical mode shows hits through the selected timestamp.
This is the as-of band-walk path, not only the first ATR level hit. Each step is the band being tested and whether price continued away from PDC, retraced toward PDC, hit both in the same bar, or ended with no next boundary.
