What is Stock trade fee?

A stock trade fee is what a broker charges to buy or sell a share or an exchange-traded fund, and it is usually quoted per trade. A free fee means no commission on the trade itself, though spread and other charges can still apply. Abf Trade Eu, Acorns Checking and ActivoBank add no commission ($0), while 5paisa charges INR 20 and Admirals charges $0.02 per trade.
