3-5 bps fee on pro orders charged on position size
Swaps
Imperial uses Titan, an aggregator, for all swaps to get you the best price. Rather than charging up to 18 bps on your swaps (like Jupiter does), Imperial charges a flat 10 bps fee (paid in USDC) on swaps.
Pro Orders
Imperial's primary product is it's pro orders. Depending on the complexity of the order, a 3-5 bps fee will be charged on the position's size.
Market, limit and TP/SL orders and are not pro orders and thus have no order fee.
