From the results of EQSRCH, you can use "Add All to New List".
For example, I have created an "equities_search" list for the results.
Then, I can use Eikon Data API to retreive RICs in that list.
df,e = ek.get_data("lists('equities_search')","TR.RIC")
I have the same problem! Don't know what to do.
