I am trying to test an automated strategy for ES by 'replaying' market data going back up to ES 03-13. I have the replay data I downloaded from internet. The challenge is when I try to add the symbols from the symbol list by going to Instrument Manager, the available symbol list for ES only goes back up to ES 04-14.
Can someone please guide me in terms of how can I load symbols beyond ES 04-14 so that I can use them for replaying the market and test my strategy?
Very much appreciate your help in advance.
Thanks!
