Options12:Quote from Options12:IBsoft, quick follow-up question on the above, are you saying that IB does not have any record of when TH has executed the opposite side of an IB customer trade (auto liq or otherwise)?
From the IB statement:
6. IB accepts liquidity rebates from Alternative Trading Systems and exchanges for certain orders. IB receives payment for some option orders pursuant to exchange-mandated marketing fee programs or other arrangements. IB does not generally accept payment for order flow for security futures orders. To the extent permissible under exchange rules, IB may direct customer stock, option, futures, or security futures orders to its market making affiliate Timber Hill LLC, or to another affiliate, for execution. In such cases IB's affiliate may act as principal in the resulting transaction and may earn a profit or incur a loss in connection with the transaction. The source and nature of any compensation received by IB in connection with any transaction is available upon written request of the customer. For further information, check the IB website or email help@interactivebrokers.com.
7. For security futures trades, if not already indicated on this statement, information about the time of any transaction, the identity of the counterparty to the transaction, and whether IB is acting as agent or principal, as agent for the counterparty, as agent for both parties to the contract, or as principal, and if acting as principal, whether the transaction was a block transaction or an exchange for physicals transaction, will be available upon written request of the customer.
Similar disclosures have been on broker's statements since I have been trading.
