A one cancels other order links two pending orders together so that when one executes, the other is automatically canceled, useful for trading two opposite scenarios from a single setup. This tool simplifies managing uncertain breakout directions, as this FXM680 guide explains.

What Is A One Cancels Other Order? An In-Depth Overview
A one cancels other order, commonly abbreviated OCO, links two separate pending orders so that the execution of either one automatically cancels the other. This is typically used when a trader wants to be positioned for a breakout in either direction from a consolidating price range.
Instead of manually canceling an unused order after the other triggers, an OCO order handles this automatically, keeping the account clean and avoiding accidental double positions.
This order type is especially popular around key events or tight consolidation ranges, where the direction of the eventual breakout is genuinely uncertain in advance.
Why One Cancels Other Orders Matter for Traders
OCO orders let traders prepare for a breakout without needing to predict its direction, placing both a buy stop above and a sell stop below a range simultaneously, confident that only the triggered side will remain active.
This tool reduces the operational burden of managing two separate pending orders manually, particularly useful when a trader cannot monitor the market continuously around a specific event.
Detailed Analysis of OCO Order Use Cases
Breakout Range Trading
A common OCO setup places a buy stop above range resistance and a sell stop below range support, capturing whichever direction the eventual breakout takes.
News Event Positioning
Traders sometimes use OCO orders ahead of major economic releases, since the resulting volatility can produce a sharp move in either direction that is difficult to predict beforehand.
Automatic Cleanup
Once either order in the OCO pair triggers, the platform automatically cancels the other, preventing an unintended second position from forming later.
| Component | Function |
|---|---|
| Order A | Pending order for one possible direction |
| Order B | Pending order for the opposite direction |
| Link | Triggering either cancels the other automatically |
Step-by-Step Guide to Setting Up An OCO Order
- Identify a price range or consolidation zone where a breakout in either direction is plausible.
- Place a buy stop order above the range and a sell stop order below it.
- Link the two orders using the platform’s OCO function, if available.
- Set appropriate stop loss and take profit levels for each side of the pair.
- Allow the market to determine which order triggers, with the other canceling automatically.
Common Pitfalls to Avoid
A common pitfall is placing both orders too close to the current price, increasing the risk of a false breakout triggering one side prematurely. Another is not all platforms supporting true OCO functionality, requiring manual cancellation of the unused order, which some traders forget to do.
Frequently Asked Questions
Does every broker support OCO orders? No, OCO functionality varies by platform and broker, and some require manually canceling the unused order instead.
Is an OCO order the same as placing two separate pending orders? Functionally similar, but a true OCO order automatically links cancellation, while two separate orders require manual cleanup.
When are OCO orders most useful? They are most useful around consolidation ranges or major news events where breakout direction is genuinely uncertain.
