Pricing and total cost
The general event-contract taker model is M × 0.07 × C × P × (1−P), with schedule rounding. Maker fees use M × 0.0175 × C × P × (1−P) on designated series; other resting orders have a zero maker multiplier. There is no membership or settlement fee. ACH deposits and withdrawals are listed as free; payment-rail and broker costs can differ.
