AM TBR

Rolling 20-Day SDEV · ±0.25 First Touch · 08:00–12:00 ET · MAE / MFE Analysis

The AM Time-Based Range opens at the 08:00. A ±0.25 SDEV level is projected from TBR Open using a rolling 20-day sample standard deviation of prior session % net changes. The study tracks whether price first reaches the +0.25 or −0.25 level and whether it subsequently reverts to TBR Open before the 12:00 close. 2,572 total sessions with 2,545 touching ±0.25 SDEV across 2016–2026.
