The Developer sent me an Archive of this years data for the 6E. So I deleted the cache in the db folder and deleted the 6E files in the Tick and Minute charts. Then I extracted this archive into the db folder. (But first I deleted minute and tick charts in NT 8 itself. Then saved this upon closing NT 8) Now when I open NT 8 I DONT connect to my datafeed and I can Backtest after I create new tick and minute charts.
I don't know if this is temporary or permanent yet. I will try and do a lot of Backtesting tonight and see.
