Reg Opening Option caluclator, Spread Order & Chart in PI as well as in ZT

Suppose myself & my brother, both of us are Zerodha’s customer.

Can i able to open PI in my account and ZT in my Brother’s account in the same desktop?

Because i want to use option calculator, Spread order as well as chart at the same time, but all the facilities are presently not available in a single platform…

Requesting your support…

Yes, you can open both ZT and PI with different accounts in the same PC

I am beleving that all the facilities will be included in PI but presently want to use the same…Request your suggestion…
