Order-Send-Order (OSO/OTO)

The term order-sends-order (OSO), also known as order-triggers-other or one-triggers-other (OTO), refers to a group of conditional orders that state that if one order (the primary order) executes, the other orders will be automatically input (the secondary order or orders). OSO/OTO orders can take many different forms, such as take-profit plans and bracketed orders. OSO/OTO orders are used by seasoned traders to limit risk and lock in profits.
