Estimate, review, then confirm

Choose a team and enter a dollar budget including simulated fees. The read-only estimate shows contracts, average price, fee and spend. It expires after three seconds, does not reserve prices and does not place an order.

Review the trading ticket’s account, team and amount, then confirm a simulated order. To sell held contracts, choose Close position. A sale that would leave less than the market minimum may close the whole position instead, subject to available depth.

What the simulator uses

Orders process after a 250 ms modeled delay against the then-available recorded book and account state. Buys use offers and closes use bids for the selected outcome.

Orders may fill partially; the remainder is cancelled. There are no resting orders or fill-or-kill instructions, and the current ticket has no user-set limit price. The model can use full displayed depth, but does not reserve venue liquidity.

Simulated US fees use the market’s fee coefficient and cent rounding. Read the actual fill and refreshed account totals: a prior estimate is not the final result.
