Strategy versions & rollback
Every strategy save — applying a preset or tuning factors manually — becomes a new permanent version, saved exactly as-is and never edited in place. The changelog table at the bottom of Settings → Strategies lists them all, newest first, with exactly one marked active.
Rollback (and roll-forward)
Activating any older version from the changelog is how you roll back — one click, takes effect from the next signal run. There’s nothing special about “backward”: activation just points your account at a version, so switching forward to a newer version works the same way.
Manual tuning
The Advanced — manual factor tuning panel offers the raw controls: the four factor weights (how much each scoring measure counts) and the strategy’s thresholds. Saving the form creates and activates a new version, same as a preset.
Version retention
Free keeps 1 strategy version; Pro keeps 10. On Free that effectively means your current setup IS your history — upgrade if you want a paper trail to roll back through.
