Advanced trading fees are calculated by IXFI using the maker-taker fee model. Orders providing liquidity (maker orders) have different fees from orders taking liquidity (taker orders).
We calculate fees based on the 30 days traded volume and it will be calculated at the time of order execution.
Taker
You are a taker if you place an order that executes immediately before going on the order book. This applies to both partial and full fulfilment of orders.
There are always takers for trades from market orders since market orders are never entered into an order book.
In other words, these trades take volume off the order book and therefore are takers.
Maker
Whenever you place an order that appears partially or fully in the order book (for example, a limit order placed on the trading screen), any trades resulting from that order are maker trades.
If your order is partially executed, some amount might go into the order book and some amount might be executed. In this case, fees will be calculated as a maker fee for the order book amount and a taker fee for the executed amount.
Making the market through these orders, which add volume to the order book, is what is referred to as a maker in subsequent trades.
