Bracket Order

Quoting

Bracket orders are designed to help limit your loss and lock in a profit by "bracketing" an order with two opposite-side orders. A BUY order is bracketed by a high-side sell limit order and a low-side sell stop order. A SELL order is bracketed by a high-side buy stop order and a low side buy limit order. The order quantity for the high and low side bracket orders matches the original order quantity.

Bracket Orders are often structured as a 'One Cancels the Other' order - see OCO
