anything similar to ADVFN's DDE feed of real time prices/values

[tolland]

Hi,

I am currently working on a tool to alert on diverging correlations between indices and I need a real time stream of prices to feed in. I have found that the LSE provide a DDE feed and ADVFN provide LSE, NYSE and FTSE/Dow indices real time.

Are there any other providers or similar data via a DDE or other API?

Thanks,

T
