A trading fee is charged only when your order is successfully executed.
The fee is not charged when you:
Browse markets.
Create an account.
Place an order that is never executed.
Cancel an unfilled limit order.
Before confirming your trade, you'll see a complete order summary showing:
The number of shares you're buying or selling.
The order value.
The applicable trading fee.
The total amount you'll pay or receive.
This ensures there are no hidden charges after your trade has been placed.
