One Triggers Other Order

A one-triggers-the-other (OTO) order allows an investor to place a primary and secondary order, with the second order being triggered upon the fulfillment of the first.

Many different combinations of order types can be used in an OTO order. For example, an OTO order could combine a buy market order with a sell trailing stop order. In this case, the broker would buy the desired assets at the best available offer and then sell the assets if and when their price falls below the trailing stop threshold.
