Reversals and Cancellations

You agree and understand that you cannot cancel, reverse, or change any transaction that has been marked as complete in your account. We reserve the right to refuse to process or to cancel or reverse, any transaction conducted under your account in our sole discretion, even after funds have been debited from your account, and we are under no obligation to allow you to reinstate a purchase or sale order at the same price or on the same terms as the cancelled transaction:

• If we suspect the transaction involves (or has a high risk of involvement in) suspicious trading activity or violations of these Terms

• If we have reason to believe there was an obvious error in any term, including but not limited to the price, amount or any other info about the trade

• If there was disruption or malfunction in the operation of any trading system

• If there were extraordinary market conditions or other circumstances in which the nullification or modification of transactions may be necessary
