Market with Protection Order
A Market with Protection order (available for futures on Globex) is sent in as a market order to execute at the current best price. If the entire order does not immediately execute at the market price, the remainder of the order is re-submitted as a limit order, with the limit price set by Globex to a price slightly higher/lower than the current best price.
