A trading fee applies when an order executes. In maker/taker models, a maker adds liquidity with an order that does not execute immediately, while a taker removes liquidity by matching existing orders. Their rates can differ.
Costs to separate
- Trading: a charge for buying, selling, or converting inside the exchange.
- Spread: a difference included between buy and sell prices in some flows.
- Withdrawal: a charge displayed when sending an asset out of the CEX; it can differ from the network cost.
- Variables: asset, network, volume or account tier, method, product, market, and region.
Purely illustrative example
- Imagine an internal trade of 1,000 units with a hypothetical 0.10% fee: trading would cost 1 unit.
- If you then withdraw, add the fee displayed on the withdrawal screen.
- The real total must use the current preview; 0.10% is not presented here as any platform's current fee.
Buying is not withdrawing
Buying inside an exchange changes your account balance. Withdrawing later is another operation with its own network, address, availability, and possible fee.
Before confirming, review the total, expected amount, and withdrawal screen. Fees can change, and a historical figure is not a substitute for a current quote.
