No verfiedList returned when calling VerifyRICs on the Instruments returned from calling ExapdnChain 0#ES3WN6+ from 2016-04-01 to 2016-08-03. Is this the right RIC for Mini S&P Week 3 Options? I got this from calling ExpandChain 0#ESW+ . I want to get the historical data for the Mini S&P Week 3 Option Chain, however, there does not seem to be any data and I am wondering if it's related to the fact that the RICs cannot be verified.
