IOC Full Form in Share Market

It is a retention order type that is used to fix the time duration of the order. The time duration for the order to execute is "IMMEDIATE or CANCEL. So when you place an IOC Order, the order will either execute or get canceled immediately in milliseconds.
Confused? Check the example below:
For instance, let’s say you place an IOC Buy Order for 100 Shares, and at that particular time, there are no shares available in the market. In such cases, the order is canceled immediately.
In IOC Order, Partial Match is also possible.
Let’s understand how partial match works by keeping the above example in mind but this time, let’s assume there were 30 shares available in the market.
As only a partial portion of your order quantity is available, only that portion "30 shares" will be executed and the remaining unmatched portion of 70 shares will be canceled.

Type of IOC Orders

You can combine the IOC Order with Limit and Market Orders:

• When you use Limit IOC Order, the order will be executed at a specific price of your choice.
• And when you use the Market IOC Order, the order will be executed at the current best available price in the market.

3. Multiple Stocks: As you have already learned, the Day Order will remain active until the market closes unless closed manually. So people who trade in multiple stocks use IOC order to avoid the risk of forgetting to cancel the order manually.
