The Passive Relative order submits a limit order at a less aggressive price than the National Best Bid and Offer (NBBO). Your price is automatically adjusted when the market moves. For a buy order, your bid is pegged to the NBB by a less aggressive offset amount*, and if the NBB moves up, your bid will also move up. For sales, your offer is pegged to the NBO by a less aggressive offset, and if the NBO moves down, your offer will also move down. 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.
For passive relative orders with a "0" offset, the order is submitted as a limit order at the best bid/ask, and will move up and down with the market to continue to match the inside quote.
Note: If you have tooltips enabled, you can hold your mouse over the Limit price of the relative order and see the current exchange price for that order.
*The offset is the amount that will be subtraced from the best bid (for a buy order) and added to the best ask (for a sell order) to create the limit price at which the order will be submitted.
