A software for margin calculation

hi
I want to now is there any software which calculates margin required for a F&O contract to trade. let me explain it.
Lets say to trade in nifty's future contract wee need 20% margin if today nifty closed say at 4000 , margin rate is 20% lot size is 50.
so calculation is 4000*50=200000*20%=40000
to trade in nifty future contract wee need Rs40000 for 1 contract as margin
if nifty were at 5000 then as per calculation wee need Rs50000 for a contract as margin money.
so my question is , is it possible to develop a software which can take eod data of a security, and the margin percentage. and calculate the margin required to trade its contract in F&O and show it in MS-Axel?

Hi Ali,

The margin which is collected by out broker is a sum of Initial margin/Span margin, premium margin(options), exposure margins and some other margins. All details can be found on NSE's risk management web pages.

Approximately, the margin required for index futures is between 10 and 15%, while for stock futures around 22 - 25%.

Your broker's terminal or website will have an margin calculator.
