Margin for USD margined options contracts is divided into options buyers (long positions) and options sellers (short positions).
Option Buyer's Margin
For the buyer of an option, the premium and estimated trading fees will be frozen as buyer's margin when placing an order, while initial margin and maintenance margin will not be required for placing orders or holding positions.
Option buyer's margin = premium + estimated fees
= order price * amount + estimated fees
Option Buyer's Initial Margin IM = 0
Option Buyer's Maintenance Margin MM = 0
Option Seller's Margin
