Taker

A taker is someone who places an order that’s matched and filled right away with an existing maker order on an exchange’s order book. This typically happens when using a market order, though it can also occur with a limit order if its price can be met immediately. When taker orders are executed, they subtract liquidity from the order book, making assets less available for others to trade. Because of this, exchanges often apply higher fees to taker trades than to maker trades.
