IB SmartRouting takes into account transaction costs along with the fee or rebate for taking/adding liquidity when determining where to route your marketable order when the inside market is shared by multiple exchanges. For clients who want even more control of their orders, TWS clients can specify stock and options smart routing strategies for non-marketable orders. For stocks, clients with the Cost Plus pricing structure can elect to have their non-marketable orders routed to:
- The exchange with the highest rebate.
- The listing exchange on the symbol.
- The highest volume exchange that has a rebate for adding liquidity.
- The highest volume exchange that charges the lowest fee for taking liquidity.
For options, clients can choose to send their non-marketable Smart routed orders to the exchange offering the highest rebate. These routing directives can be set on a per-order basis from the "Misc" tab of the Order Ticket, or as a global default setting from the Smart Routing configuration page.
