Nifty Futures Profit / Loss Calculations during a Series

This is the question to all the senior and experienced traders of TJ,

Suppose on 1st I bought NF (Min) 1 lot at 5200 and I didnt sell it ... What will happen in the following scenario :

1. That day market closed at 5250.
2. Next day market closed at 5300.
3. On third day I sold at 5250 but it closed at 5150.

Now according to me (as per equity trades done by me earlier), my profit should be 5250 - 5200 = 50 Points !!!

But I somehow feel that it is calculated in some other fashion in NF ... It is considered each day at the closing Price ...

So, please guide me as to what would be my profit / loss in such a scenario .

Thanks,

Ajit

Thanks for your reply. But I actually wanted to ask that whether each day, the calculations would be done separately .... Becoz, if I buy at 5200 and i sell at 5250 after 10 days ... Won't I get 50 points straight profit ... Or it would be calculated on what happens between those 10 days ... (market may go from 5200 to 5400 and back to 5250 within that) ... Sorry, but just curious about that ...
