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 67 closed positions this score is based on skew toward wins by construction, not necessarily by skill. An estimated 93% of 88M'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.
