Is there an easy way to get the option chain RICs from the underlying RIC without infering them? Indeed, it is often the case that the Rics are not related, e.g. ABC.AS is the underlying RIC and 0#YZX*.E is the option chain RIC..
Using DIB I see that there are no fields that we could directly use. The META app seems to contain this information under "Related". Is there a way to extract data from the META app in the API?
