A maker is a party whose order exists on the order book before the trade occurs.
Makers are incentivized because their orders make the liquidity in a market.
A taker is a party who places an order that matches the makers' order.
Takers are the ones who remove this liquidity by taking makers' orders with their own.
Fee will be deducted after the order is completed and will be deducted from the currency that you have recieved in that order.
