Search Strikes by Underlying Contract ID

Query to receive a list of potential strikes supported for a given underlying.

This endpoint will always return empty arrays unless /iserver/secdef/search is called for the same underlying symbol beforehand. The inclusion of the name field with the /iserver/secdef/search endpoint will prohibit the strikes endpoint from returning data. After retrieving your expected contract from the initial search, developers looking to create option chains should remove the name field from the request.
