I have a problem..my June contract / symbol for both emini and big s&p just disappear and I don't know why. I would like to keep this history to look back on past trading days. This has happened every time a symbol expires also another problem I have noticed is my global server and my turbo feed data manager always have to be online in order to view a chart or past history, is my data not stored on my computer . thanks for any help you can give
