IBUSOPT Destination

Why pay the spread to take liquidity for your options orders? IBKR clients can now add liquidity and interact with our retail order flow by direct-routing their US equity and index options orders to the IBUSOPT destination.

Orders routed to IBUSOPT will be held at this liquidity-providing destination, and will be eligible to participate in an exchange auction to potentially fill against other SMART-routed marketable orders from IBKR clients.

  • All IBUSOPT orders will be used to start an auction at the exchange.
  • Orders routed to IBUSOPT are not guaranteed to fill.
Route options to IBUSOPT

To route a US equity or index options order to IBUSOPT from Mosaic, set up the order in the Order Entry panel and open the "advanced" panel to select a new destination. Once you have selected IBUSOPT as the destination, available order types will be shown in the dropdown. Choose from a variety of order types to post liquidity to the IBUSOPT destination, including:

Orders routed to IBUSOPT may count towards your professional customer threshold and may therefore impact your customer status. Customers resting pegged orders in IBUSOPT for participation in RFQ auctions should be aware that a pegged order will be treated as canceled and replaced each time such order participates in an RFQ auction in IBKR's system (whether or not such order becomes an initiating order in an on-exchange auction). For more information, please see IBKR's Priority of Professional Customer Orders article.

The Reference Table to the upper right provides a general summary of the order type characteristics. The checked features are applicable in some combination, but do not necessarily work in conjunction with all other checked features. For example, if Options and Stocks, US and Non-US, and Smart and Directed are all checked, it does not follow that all US and Non-US Smart and direct-routed stocks support the order type. It may be the case that only Smart-routed US Stocks, direct-routed Non-US stocks and Smart-routed US Options are supported.
