Leg Prices and Leg Products

Complex FLEX order legs must be for the same underlying product and the same exercise style (American or European). Complex FLEX order legs must be for the same settlement type if using Asian or Cliquet, however, A.M. or P.M. settlement types may be mixed. Complex FLEX order legs cannot be listed as a standard option.

Complex FLEX orders must contain a starting price for each leg in addition to the net package price for the order, except for orders routed to the floor, which may contain a price for some, all, or none of the legs. Responses will be in net price only. When an order is filled at the final net price, the system generates leg fill prices that are as close as possible to the submitted leg price.
