I am searching for several years of daily data for DAX/ESTX50. Cash index data which I get from ESignal or Yahoo is not really valid. The opening gaps are either nonexistent or smaller than they really out to be. I think this is a problem with EUREX. ESignal does not provide continuous contract for EUREX futures as it does for CME. Is there a reliable source for 1. cash index data 2. continuous contracts 3. some other proxy which I could use to track dax/estx (maybe there is some european ETF similar to QQQ or SPY). ??? Thanks!
