Binance OCO Orders
An OCO order, or a one-cancel-the-other order is essentially an order which combines a Limit Order with a Stop Limit Order.
This creates a form of automation in that when the pair of orders are created, it will only be possible for one of the orders to be successfully triggered.
To put it simply, as soon as one order has been executed, the remaining order will be automatically cancelled. This aids with maximising profit and minimising losses. An OCO is a way in which you can trade in a more secure way by limiting risks and locking in profits.
