What is a transaction type OPT_FIN_INX
A OPT_FIN_INX is an option that results in a payment (cash settlement) rather than in the right to do another trade at the strike price. The difference in CpML is that there is no Fixed Price Information section for a OPT_FIN_INX, just the Delivery Periods (volume and settlement information) and the Floating Price Information (the description of the index) which is used to determine the option value with respect to the Strike Price.
