The T3 Deviation indicator is not a standard deviation smoothed by T3. Instead, it utilizes intermediate steps of the T3 calculation to derive a deviation that is inherently smoother due to the nature of the T3 algorithm, which is smoother than a simple moving average. This results in a more responsive indicator that adapts quickly to market changes.
The original concept was introduced in 2026, building upon the work of Tim Tillson's T3 calculation.
