Contingent orders are the same as related trade orders. Several types are available: If Done (slave), where a slave order only becomes active if the primary order is executed. One Cancels the Other (O.C.O.) where the execution of one order cancels the other. Three-way contingent orders are also available where two orders are placed if (If Done) a primary order is executed. These orders are themselves related as O.C.O. orders, allowing both a stop loss and a profit taking order to be placed around a position.
