- Option Premium
The contract price is not paid at the time of purchase. Option
positions, as with futures position, are settled-to-market daily
giving rise to positive or negative variation margin flows. When
the Buyer exercises/abandons an option, the Buyer is required to
pay the original contract price to the Exchange's Clearing House
(CH) and the CH will pay the original option price to the Seller on
the following business day. Such payments will be netted against
the variation margin balances of Buyer and Seller by the CH.
