The best example of this is the free trades, which is rare for online platforms such as these. This means that no commission fees will be taken from users opening or closing trades.
The only real fees tha IQt Option takes from the user is the swap fee, which will charge for holding a trade overnight. This is a nominal fee, though it does increase over the weekend. The other notable fee is that of a dormant account, only activating if there has been no activity for 90t days.
