Three sentences to explain trading fees:
A Maker order rests on the order book waiting to be filled, providing liquidity to the market; a Taker order is filled immediately against an existing order on the order book.
For short-term traders who enter and exit positions frequently, fees can add up to more than you expect and make a significant dent in your final returns.
When calculating your break-even price, include the fees for both opening and closing the position—and be especially mindful when using high leverage.
