Ethfinex implements a maker-taker fee model.
Maker fees are paid when a trader adds liquidity to the order book. This is done by placing limit buy orders below the current price, or limit sell orders above the current price, and allows you to earn NEC.
Taker fees are paid when a trader removes liquidity from the order book. This occurs when an an order is executed against an order on the order book.
Placing a market order incurs a taker fee, as the order executes immediately against the order book.
Placing a limit order incurs a maker fee, if executed, as the order adds liquidity to the order book.
If you place a hidden order, you will always pay the taker fee. If you place a limit order that matches a hidden order, you will always pay the maker fee.
There are no fees associated with creating or maintaining an Ethfinex account, or for storing your funds.
Deposits & Withdrawals
There are no fees associated with depositing Ether or tokens to your Ethfinex account. However small withdrawal fees are required in order to cover the associated network transaction costs involved with processing these. Withdrawal fees are constantly updated to reflect the Ethereum network congestion and average gas prices. This allows us to ensure we continue to provide the best experience and rapid withdrawals.
