An OCO order, short for one-cancels-the-other, links two exit orders so that execution of one cancels the other. Binance Academy explains it as a combination of a limit order and a stop-limit order, usually used to define both a profit target and a maximum acceptable loss for an existing spot position.
The workflow is straightforward: choose the trading pair, open the spot order panel, select OCO, enter the take-profit price, enter the stop trigger, enter the stop-limit price, and confirm the amount. Binance’s support guide emphasizes that the stop side has two prices, and that distinction is where many beginners make mistakes.
The key risk is execution. A stop-limit order does not guarantee an exit at any price. If the market falls through the limit price too quickly, the order can remain unfilled. That is why the stop trigger and the limit price should leave enough room for normal volatility, especially in thin altcoin books.
Advanced users may also compare OCO with OTOCO, where an entry order triggers a later OCO exit pair. OTOCO can automate a full bracket trade, but it also creates more points where slippage, partial fills and wrong sizing can matter.

Risk notice: Order tools reduce manual work but do not remove market, liquidity or platform risk. Test small before using any advanced order type with meaningful size.
