Hi @Diver Dan hope you dont mind i called you over here, i have a question i believe you might know the answer too which probably wouldnt mean too much over in the STT channel. Since you often post on the ES, i believe that you have experience trading the e-mini future indexes? I ask because i am going over a bit of course material that refers to the TF which i know is the old russell 2000 emini on ICEus. I have read that it was shut down half way through 2017 and moved over to CME and is now @RTY. the thing i was hoping that you might be able to answer for me is are they essentially the same thing just different code? Did one replace the other or did they merge? I am testing a few strategies on RTY historical data, will this be the TF data or did RTY already exist pre mid 2017 when the TF was closed down and moved over?
