The Market Taker accepts the order placed (to execute a purchase or sale at the quoted price). This is the basic completion of a market trade: someone makes an offer, and someone else accepts it.

Think about it: by placing an offer in the order book, we can increase the liquidity of the exchange because it makes it easier for users to buy or sell. On the other hand, takers remove some of that liquidity with market orders - instructions to buy or sell at the current market price. When they do this, the existing orders in the order book are immediately filled.

Many exchanges generate most of their revenue by charging trading fees for matching users. This means that every time we place an order and it is executed, we pay a small amount in fees. However, the amount differs from exchange to exchange, and can also vary depending on the size and role of our trade. In many cases, takers pay higher fees than makers, as they do not provide the liquidity that makers do.
