Basically, the margin shown here changes from day to day: https://zerodha.com/margin-calculator/Futures/ So, margin will be different on different days for the same instrument e.g. NIFTY futures. So, need a way to retrieve the historical margins for an instrument for realistic backtesting.

I am afraid we can't provide historical margins data as we don't store those files.
