ED, TY Spreads

I'm trying to find a site that will allow me to chart historical prices on eurodollar spreads..

z8h9 for instance..

I was using futuresource but there symbology has changed and now I keep getting an "incorrect contract" error.

Any ideas?

Thanks

 

Try http://www.mfglobalfutures.com/resources/getquotes.cfm?page=cspread

 

FutureSource free premium charts can still do that .. Check the FAQ for charts. For this example:
= 'ED Z8' - 'ED H9'
