Understanding One-Cancels-the-Other (OCO) Orders

What is a one-cancels-the-other order?

A one-cancels-the-other (OCO) order is a strategic combination of different trading order types, such as limit orders and stop orders, allowing traders to concurrently set stop-loss and profit objectives for their positions.

Types and Functionality of OCO Orders

OCO orders are conditional orders used in trading to place two orders simultaneously: a primary order and a secondary order. These orders are structured in a way that if one is executed, the other is automatically canceled. By employing OCO orders, traders can effectively manage risk and establish precise entry and exit points. They also enable automation, reducing the need for constant market monitoring and providing greater control in volatile markets.

Implementation of OCO orders in the Crypto Market

The implementation of OCO orders varies across crypto exchange platforms. While some platforms offer direct options for selecting simultaneous order types, others may require manual pairing of orders, where traders must independently create and bundle orders for OCO.

How Does an OCO Order Work?

OCO orders offer a comprehensive way to manage positions and automate risk management and profit-taking strategies.

Illustrative Example: Alice and her Bitcoin (BTC) OCO Order

Alice uses an OCO order to automate her Bitcoin trades, setting upper and lower boundaries for take-profit and stop-loss orders based on the current trading range. She specifies a timeframe for executing both orders, ensuring consistency in her trading strategy.

Alice successfully executes the buy order when Bitcoin's price breaks above the defined resistance level, triggering the take-profit order. Simultaneously, the corresponding stop-loss order is automatically canceled, safeguarding her investment without constant market monitoring.

When to Use OCO Orders in Trading

OCO orders offer flexibility and versatility across various trading scenarios, making them suitable for traders with diverse objectives.

Day trading with OCO orders

For day traders requiring prompt decision-making, OCO orders provide predefined exit points, allowing them to focus on market analysis while automating risk management and profit-taking strategies.

Risk management with OCO orders in open positions

In managing risk, OCO orders dynamically adjust stop-loss levels as asset prices fluctuate, offering protection against market volatility while still allowing profit-taking during positive trends.

Breakout trading with OCO orders

OCO orders are beneficial for breakout trading, enabling traders to capitalize on price movements above or below support or resistance levels without unnecessary risk.

OCO orders for market news

During periods of news-driven market volatility, OCO orders automatically respond to price changes, allowing traders to seize opportunities without constant monitoring.

Advantages and Disadvantages of OCO Orders

While OCO orders offer effective risk management and time-saving benefits, they may present challenges, including complexity and higher fees on some exchange platforms. Additionally, partial fills and execution speed limitations can impact trade outcomes.


Despite potential drawbacks, OCO orders remain a valuable tool for crypto traders, offering a systematic approach to risk management and profit-taking across various trading scenarios. Understanding their functionality and considering individual trading objectives are essential for maximizing their benefits while mitigating risks.
