FESX is the EuroStoxx 50 future over here, we just call it FESX for short.
Yes, I often chart also Euro Bund futures in different time intervals. It is also interesting because they start trading on hour earlier that FDAX & reactions in bund market to overnight (and Asia happenings) news is worthwile I think.
DAX correlation with SPX/NQ/INDU does rotate, so its possible to track that with correaltion studies inside TradeStation or so...
Best & good trades,
