No independent base rate yet. Until we connect one (sportsbook consensus, forecasts, the score), the market's own price is the best public forecast, and the fee sits on top of it.
Luck needed meter
81% 😈
Mostly luck. The market itself expects the favorite to lose this often; the fee is the only certainty.

Resting orders pay no fee on this series. Formula: 7% × contracts × price × (1 − price), rounded up, on orders that take liquidity. Break-even assumes you hold to settlement; trading out early pays the fee twice.
