## Comment on Futures & Options Filters

I was wondering where can i find link for interest calculation charged on margin for overnight positions.

I had cash margin of 1.5 lakhs and collateral margin of 5 lakhs approx, I had taken overnight position of 5.5 lakhs, however I think Zerodha has a rule where they will fund 50 percent free of cost of collateral margin that is 1.5 lakhs in this case. So the interest chargeable is on 2.5 lakhs @0.05 percent per day.

Is this correct?

Also is there a calculator for same, i do more of covered calls so need to understand the cost of carry.
