- Worth noticing
- The page labels its dataset as six days and says a full 30-day window will not exist until 2026-10-16.
Field notes
The rule editor turns a sentence into a trigger, filter, take-profit, and stop-loss; anything it cannot parse stays unresolved rather than being silently filled in. A sample panel reports 96 launches, a 36% win rate, and a -7% deepest roll, while a separate notice says the tank contains only six recorded days. The page says sealed predictions cannot be rewritten and later compares voyages against their sealed bands.
