Upload Underlying File

Using the Market Maker tool, customers can make appointments by class. A class appointment will require Market Makers to provide two sided quotations in series open for trading for that class, excluding any adjusted series, any intra-day add-on series, any Quarterly Options Series, and any series with an expiration greater than 270 days.

An explanation of each field option is available by selecting the Info icon next to the field. Customers can choose to replace an existing underlying with a new upload, add an underlying security in the upload or remove all series in the upload by selecting the corresponding option in the Mode dropdown.
