Pegged to Midpoint orders seek to execute at the midpoint of the National Best Bid and Offer (NBBO). The order price adjusts automatically to peg the midpoint if the market moves. If the market moves in the opposite direction, the order will execute.
The limit price acts as a price cap to prevent your order from being executed above or below a specified level.
