Heads up: a win has to be redeemed to become real money, but a losing position that settled at $0 never has to be -- so the 41 closed positions this score is based on skew toward wins by construction, not necessarily by skill. An estimated 98% of Zzzz87's real money hasn't gone through that filter yet, so the Avg edge and Sirtio Score above could be flattering their true record until more of it resolves.

The exact weighting is part of the model we keep private (see methodology), but every number above is this trader's real, calculated value at that step.

The best single trade in this window was +$4,023 on "Will Chelsea FC win on 2026-10-31?" (a 112% return). The worst was a -$7,468 loss on "Timberwolves vs. Cavaliers". That single trade alone accounts for more than half of this trader's total realized gains in the window, worth keeping in mind when weighing consistency.
