Fees - current builder fees is 1% of all trades
The below data will be applicable soon (to be announced)
Trading fees are calculated as a variable percentage of the expected payout for each contract. This expected payout is determined by taking the maximum possible earnings and multiplying it by the implied probability of achieving those earnings (which is simply the contract price divided by $1). Fees are applied for buys and sells / opening and closing of positions.
The fee you pay for a trade, in dollars, follows this formula:
fee = round up (0.07 × C × P × (1 – P))
Where:
P is the contract price in dollars (e.g., 50 cents = 0.5)
C is the number of contracts being traded
round up means the amount is rounded up to the nearest cent
