Web Trader MT5
An OTO, or one triggers other, is a pair of orders where the first, once filled, automatically places the second. Unlike an OCO, where two orders sit live together and one cancels the other, an OTO is sequential: nothing happens with the second order until the first has actually executed.
It is a way to set up an entry and its follow-on exits in a single step, so you do not have to be watching the moment your entry fills.
Example: A trader wants to buy a stock only if it dips to 95, and then, once she owns it, to protect it with a stop and a target. She builds an OTO: the primary order is a buy at 95, and attached to it is a bracket that springs to life the instant that buy fills, placing her stop-loss and take-profit automatically. If the stock never reaches 95, nothing triggers and no exit orders are ever created.
