Partial Exercise

No, you cannot partially exercise the contracts; you will have to partially close these contracts and then exercise the rest. We are actively working on providing partial exercise as well.

Early Exercise

Yes, you can early exercise your long position, like buy call and buy put if you have enough cash/shares available in the Brokerage account and the contact is in-the-money (ITM). For Short positions there is a probability of early assignment if the long holder decides to exercise them before the expiry date.
