Intermarket Sweep Orders (ISOs)

GTN will not accept or accommodate intermarket sweep orders, also known as ISO orders. An intermarket sweep order is generally a large quantity limit order that is sent to multiple exchanges simultaneously.  The trader submitting this type of order is required to fulfill Regulation NMS order protection obligations and exchange rules by simultaneously sending orders to market centers with better prices than the defined order limit. Since GTN does not currently have capacity to independently verify protection obligations, GTN’s clients may not set up or process such orders.

Should GTN engage in processing ISOs, GTN will provide you with exclusive permission to do so based on its vetting of the system being used being compliant with all necessary requirements.
