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 Houser (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.
