How are spot trading fees calculated? What are you charged for? Don’t worry, your study buddy is here:
Spot trading fees are generally calculated by multiplying the transaction amount by the fee rate. You’re charged once per trade, and if an order is only partially filled, you’re charged only on the portion that was filled.
For people who trade frequently, each fee may seem tiny, but they can add up to a significant amount over the course of a year.
Don’t laugh—I only remembered after learning the hard way myself.
