Fade price when it deviates N standard deviations from the session VWAP. Classic mean-reversion for range days.
“Price rubber-bands around fair value. When it stretches too far, it snaps back. Works best on quiet, range-bound sessions — stay out on trending days.”
A config in this family reached PROMOTED status in the rolling walk-forward (top-5 train AND OOS SQN > 1.0 in at least 3 of 4 rolling windows on legacy_5m). Most robust badge in the library.
This strategy: On legacy_5m, configs sd30×2 and sd40×2 were PROMOTED in rolling Mode B (top-5 train AND OOS SQN > 1 in 3 of 4 windows; mean OOS SQN 0.81 and 1.49 respectively). Mode A PASS: sd30×2 (OOS SQN 1.62) and sd20×1.5 (OOS SQN 1.06). The featured legacy_60m config was not directly tested — family robustness is the basis for the badge.
TV multi-year on 5m (sd40×2 variant): the rolling walk-forward champion did NOT replicate. -36k MYR with PF 0.52. The 1-month signal was a sampling artefact.



Range-bound / low-volatility regimes. Avoid strong trending sessions.
