In general, all orders are charged a maker or taker fee. Maker fees are paid when you add liquidity to our order book by placing a limit order under the ticker price for buy and above the ticker price for sell. Taker fees are paid when you remove liquidity from our order book by placing an order that is executed against an order of the order book.
A Post-Only Limit Order ensures that you will pay the maker fee and not the taker fee unless matched with a hidden order.
If after checking this, you believe you have been incorrectly charged contact us through our support channel, and provide us with the order ID, in question.
