What does Day, Immediate and Minutes Validity mean?

Validity:

1. Day: A Day order will be placed to execute for a specific price for the day and if the price is not executed then the order will expire automatically at the end of the trading day.
2. IOC (Immediate or Cancel): IOC orders are placed to buy or sell the security that must be executed immediately otherwise the order will be cancelled automatically.
3. Minutes: Similar to IOC these orders validity is for the minutes you opt for (like 1 minute, 5-minute, 10 minute). If the price is reached at the expected price within the minute only then the order will execute otherwise the order will expire automatically.
