Crypto markets are made up of makers and takers. Market makers create buy or sell orders that go on the order book, which aren’t executed immediately. For example, placing a limit order to sell 1 BTC when the price hits $50,000. These orders create liquidity for the market so that it’s easier for other traders to instantly buy or sell BTC when the condition is met. Traders that buy or sell instantly are called takers. In other words, takers fill the orders created by the makers.
Exchanges typically incentivize makers to provide liquidity with lower fees for their orders. If you’ve checked our fee schedule, you will see that Binance charges different fees depending on whether you’re a maker or a taker. For VIP users, makers incur smaller fees than takers. Let’s dive deeper into both roles.
When you place an order that trades immediately before going on the order book, you are a taker. This is regardless of whether you partially or fully fulfill the order.
Trades from market orders are always takers, as market orders never go on the order book. These trades are "taking" volume off the order book, and therefore are taker trades.
Limit immediate or cancel (IOC) and limit fill or kill (FOK) orders (accessible via the API) are also always takers orders.
When you place an order that goes on the order book partially or fully, such as a limit order, any subsequent trades coming from that order will be maker trades.
These orders add volume to the order book, help to make the market, and are therefore termed makers for any subsequent trades.
