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.
Taker:
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 are also always takers orders.
Maker:
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.
Note:
- A limit Good Until Canceled (GTC) order can be traded as both a taker and maker order.
- Using a limit order does not guarantee that your order will be a maker order.
- If you want to make sure the order goes on the order book before it is filled, please select “Post only” when placing your order
