Past Expiry Instruments

[jbhansen7]

Hey guys,

I want to run backtests on the ES for an automated strategy I have. Currently when I go to the strategy analyzer, the only instrument I have is the ES 03-09....can I run backtests on this from 1-1-08 through 2-23-09....or do I have to go get the ES 03-08, ES 06-08, ES 09-08, and ES 12-08, and run the respective trading dates for each?

As always, thanks for your time and your helpful answers (WAY better than Trade Station forums by the way I hear)

Thanks,

Jonathan Hansen
