An Immediate or Cancel (IOC) order is a type of Forex order that prioritizes speed while allowing partial execution. Unlike Fill or Kill (FOK) orders, which require the entire order to execute immediately or be canceled, IOC orders execute as much as possible instantly, and any unfilled portion is automatically canceled. This makes IOC orders ideal for traders who want fast execution without the constraints of full order size.

What Is an Immediate or Cancel (IOC) Order?
An IOC order is an instruction to the broker to:

Execute the order immediately at the specified price

Cancel any portion that cannot be filled instantly

This ensures rapid trade execution while accommodating partial fills, which is useful in fast-moving Forex markets where liquidity might vary.

Why IOC Orders Matter
1. Speed and Flexibility
IOC orders allow traders to enter or exit positions quickly while still capturing as much of the trade as possible.
2. Partial Execution Advantage
Unlike FOK orders, IOC orders don’t require the full order to execute, so you don’t miss out entirely if liquidity is insufficient.
3. Useful for Volatile Markets
During news releases or sudden price spikes, IOC orders help traders lock in favorable prices quickly without being stuck waiting for full execution.

How IOC Orders Work in Forex
Example

You want to buy 100,000 EUR/USD at 1.0950

Place a Buy IOC order at 1.0950

If only 60,000 units are available immediately → 60,000 units execute, 40,000 units are canceled

You still get partial exposure without waiting for the full order

IOC orders provide flexibility in fast markets while preventing unnecessary delays.

When to Use IOC Orders
✔ Scalping or Short-Term Trades – Quick execution matters more than full size
✔ News Trading – Enter positions quickly during volatile events
✔ Liquidity-Sensitive Trades – Capture available volume without waiting for full execution
✔ Breakout Strategies – Quickly enter trades at momentum-confirmed levels

Risks of IOC Orders

Partial Exposure – May not achieve desired trade size

Missed Opportunities – Unfilled portions are canceled, which can affect strategy

Requires Monitoring – Traders need to manage remaining positions if partial fills are frequent

Tips for Using IOC Orders Effectively
✔ Use on highly liquid currency pairs to maximize execution
✔ Combine with technical analysis to choose precise entry points
✔ Avoid IOC on illiquid pairs where partial fills may not be meaningful
✔ Incorporate stop-loss and take-profit orders for proper risk management
✔ Adjust order size to match market liquidity expectations

Final Thoughts
Immediate or Cancel (IOC) orders provide speed, flexibility, and partial execution for Forex traders, making them a strong choice for scalpers, news traders, and anyone operating in fast-moving markets. Unlike Fill or Kill orders, IOC allows traders to capture what is available immediately while canceling the rest, balancing efficiency and practicality. Mastering IOC orders can help traders react to market opportunities with precision and confidence.
