How much does Interactive Brokers cost?
Commissions are $0.005 per share. Data fees are separate. If you pay over $30 per month in commissions the fees for level 1 data feeds are waved. Otherwise that is $10 a month. I pay $2.50 per month for Pink Sheets level 1. I recommend paying $15 per month for Nasdaq Totalview, but I have Level2 through other brokers so I do not subscribe to that.
