Order Validity

•Day - A Day Order. The order expires when market closes if it is not filled during the day. This is useful for traders who wish to enter at a certain fixed price for the day and if they don't get it, they would rather not take the position.

•IOC (Immediate Or Cancel) - A Market Order or Limit Order which is automatically canceled unless executed in whole or in part immediately after its receipt.

•GTC (Good Till Cancel) - The order will be active till you cancel it. Good-till-Cancel orders are rejected at end of day if they fall beyond the daily price fluctuation limits.

•GTD (Good Till Date) - The order expires at the end of the specified date. Good-till-Date orders are rejected at end of day if they fall beyond the daily price fluctuation limits.

•FOK (Fill Or Kill) - A Fill-Or-Kill order is an options order that cancels if it is not filled entirely upon execution. This is specially used for large orders and requires immediate execution.

•AOP (At the Opening) - An order to buy or sell at a limited price on the initial transaction of the day. If the order, or any portion of it is not executed in this manner, it is to be treated as canceled.
