Hello !
I have been using for many years RIC 1RTY and 1YM to collect data on RUSSEL and DOW JONES.
First question : What is the difference between the RIC ROOT RTY and 1RTY (or between YM and 1YM) ?
Second question : Why the RIC 1RTY is seen as historical since a few days ? See screenshot
How can we track those changes ?
Thank you for your help
Kind regards
