Passive Relative orders provide a means for traders to seek a less aggressive price than the National Best Bid and Offer (NBBO) while keeping the order pegged to the best bid (for a buy) or ask (for a sell). The order price is automatically adjusted as the markets move to keep the order less aggressive. For a buy order, your order price is pegged to the NBB by a less aggressive offset, and if the NBB moves up, your bid will also move up. If the NBB moves down, there will be no adjustment because your bid will become aggressive and execute. For a sell order, your price is pegged to the NBO by a less aggressive offset, and if the NBO moves down, your offer will also move down. If the NBO moves up, there will be no adjustment because your offer will become aggressive and execute. In addition to the offset, you can define an absolute cap, which works like a limit price, and will prevent your order from being executed above or below a specified level. The Passive Relative order is similar to the Relative/Pegged-to-Primary order, except that the Passive relative subtracts the offset from the bid and the Relative adds the offset to the bid.

  • Passive Relative Buy Order

    Order Type In Depth - Passive Relative Buy Order

    Step 1 - Enter a Passive Relative Buy Order

    When you use a Passive Relative order, the value in the Limit Price field becomes the price cap, and the order price is calculated (but not displayed) using the NBB minus the offset amount (the relative amount) for a buy order, and the NBO plus the offset amount for a sell order. You want to buy 100 shares of XYZ, and you want to place a less aggressive bid than the current best bids to increase your chance of filling at a better price.

    The current NBBO for shares of of XYZ stock is $24.01 - 24.06. You create a buy order for 100 shares and select PASSV REL as the order type. You enter 24.03 as the limit price, which is the price cap for your order; this is the most you are willing to pay. You enter an offset amount of 0.02, then transmit the order.

    Assumptions

    Market Price (NBBO) Range $24.01 - 24.06

    Step 3 - Price Rises, Order is Not Executed

    The market rises and the NBBO for shares of XYZ rises to $24.03-$24.08. Your bid moves with it to $24.01. The order does not execute. If the market continued to rise to $24.03-24.07, your bid would be capped at $24.03.

    Assumptions
    Action BUY

    Order Type PASSV REL
    Market Price (NBBO) Range $24.03 - 24.08
    Limit Price (Price Cap) 24.03
    Offset (Relative) Amount 0.02
    Bid 24.01

The Reference Table at the top of the page 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.
