Validity of orders are DAY,COL,IOC.I could understand DAY.
What do COL - IOC mean and its implication ?
COL: Cancel on logout (so all your pending orders get cancelled when you logout of the trading application)
IOC: Immediate or cancel (So if your entire quantity and price is not filled immediately when you place an order, it gets cancelled).
ThanQ Nithin.Now I am clear.
