## Comment on Zerodha - Margin Policies

Hello,

I am new to futures, trying to understand few things.

Please excuse me if i dont make any sense.. so here is the question.

Say i am doing intra day on nifty :

I sell nifty future at say 8000 which has lot size of 25, so how much money should my account have .

8000 * 25

The calculator here @ https://zerodha.com/margin-calculator/Futures/ shows less, so how the amount is calculated which i should have for intraday.

Now while squaring off for the day , i buy back nifty futures at 7990 with a profit of 10 points,

now how will be profit calculated, will it be 10 * 25 or the margin difference.

I hope my question is clear.

Regards

Akshay
