In order to keep all the historical data in each contract, I have exported de ES 03-11 (with 10 years of historical data wich ends tha day of the expiration of that contract), and I have imported it with the name ES 06-11. When I do that the historical data imported and kept now in the new contrat appears in the chart with 1 hour o diference in compare with ES 03-11. I have cheched my p.c. windows clock and everything seems to be actualized.
Any clue to solve this issue?
Thanks
