For all Service Levels, you can choose to subscribe on either a Monthly or an Annual basis. With our Monthly Renewal option, you pay for one month of service at a time, and your account will simply renew automatically each month. With our Annual Renewal option, you prepay for 12 months of service, and we'll give you the 13th month for free. If at any point you'd like to change your Service Level or renewal preferences, you can always do so from the Your Account page.

All Data Plans are billed separately from your Service Level subscription and are always billed monthly. Prices vary as they reflect the fees charged by the exchanges for your use of their real-time data. Data Plans may be added or removed at any time from the Your Account page. Unless removed from your account, Data Plans renew automatically at the end of each billing month. If you do choose to remove a plan, the change will take effect at the end of the billing month. All Data Plan charges are non-refundable.
