A los que preguntásteis por las comisiones de Interactive Brokers, me acaban de mandar esto:
The fee of USD 10 per month, or USD 20 if your account balance is below USD 2,000, is waived during your first three months following the funding of your account to allow you time to familiarize yourself with our platform.
Please note that the fee is offset by any commissions you generate during the month. In addition, the fee may be reduced if your account balance is in excess of USD 100,000 or you are age 25 or younger.
