One-Cancels-Other (OCO) order

An OCO order or One-Cancels-Other, is a conditional order. An OCO order allows you to combine 2 different orders under special conditions - once one of the orders is triggered and executed, the second order is automatically cancelled.

The screenshot above shows an example of an OCO combination of 2 different orders: Buy Stop order + Sell Limit order. If either the Stop or Limit price is reached and an order is executed, the 2nd order automatically gets canceled.

An OCO order allows you to combine different as well as identical order types: Stop+Limit, Stop+Stop, Limit+ Limit.
