Trade amounts are executed as multiples of the minimum trade quantity for the relevant trading pair. For example, the minimum trading amount for the USDT/TRY trading pair is 1 USDT. Assuming the current price of 1 USDT is 27 TRY, if you enter 30 TRY in the buy amount field, the remaining 3 TRY will not be processed and will stay in your wallet.
