Suppose I place a limit order of 100 quantity in NIFTY CE. Out of which only 50 quantity is filled.
In between this, if I cancel the remaining order, will the order be market as CANCELLED or COMPLETED?

I’m not sure, but you cannot cancel a partially filled order. The system will automatically cancel it at the end of the day.

It will be cancelled, but we highlight in order book if it is partially traded.
