Where do i get option calculator for calculating theta delta gamma etc? I tried it in zerodha trader but it is not logging in saying DISCONNECTED FROM THE NEST SYSTEM. Pls help

Zerodha Pi should soon be coming out with Greeks calculator, Risk Profile graphs, Delta Hedging(?!), etc. You can also download excel version by googling, or download exe version from Sharekhan website.

THANKS A TON
