IOC Orders in Zerodha

What is an IOC order?

An IOC order is a type of order that is executed immediately, either partially or in its entirety. If any part of the order cannot be executed immediately, it is canceled. Unlike other order types, IOC orders do not have a time limit for execution. They are designed to provide traders with flexibility and control over their trades.

How do IOC orders work?

When you place an IOC order, it is sent to the exchange for immediate execution. If there is sufficient liquidity in the market, the order is executed at the desired price. However, if there is not enough liquidity to fill the entire order, only the available quantity is executed, and the remaining quantity is canceled. This ensures that you do not end up with unwanted open positions.

Advantages of using IOC orders:

1. Flexibility: 

IOC orders offer traders the flexibility to execute their trades immediately without having to wait for the entire order to be filled. This is particularly useful in volatile market conditions where prices can change rapidly.

2. Control: 

By using IOC orders, traders have better control over their trades. They can specify the exact price at which they want to execute the order and avoid any slippage that may occur in the market.

3. Risk management: 

IOC orders help traders manage their risk effectively. By executing only a part of the order that can be filled immediately, traders can limit their exposure to market fluctuations and minimize potential losses.

4. Time-saving: 

IOC orders save traders time by eliminating the need to constantly monitor the market for price changes. Once the order is placed, it is executed immediately, allowing traders to focus on other aspects of their trading strategy.

Limitations of IOC orders:

1. Partial execution: 

One of the limitations of IOC orders is that they can be partially executed if there is not enough liquidity in the market. This can result in traders having open positions that are smaller than initially intended.

2. Price impact: 

IOC orders can have a price impact on the market, especially if the order size is significant. This is because IOC orders are executed immediately, which can affect the supply and demand dynamics in the market.


In conclusion, IOC orders are a valuable tool for traders looking for flexibility and control in their trading strategy. By understanding how IOC orders work and their advantages and limitations, traders can make more informed decisions and effectively manage their risk. Whether you are a beginner or an experienced trader, incorporating IOC orders into your trading plan can enhance your overall trading experience. So, next time you trade on Zerodha, consider using IOC orders to optimize your trading strategy and maximize your returns.
