Wikinvest UK?
 

Like, I suspect, many here, I have a pension fund in the UK as well as an IRA here.
I use the excellent Wikinvest.com to track my fund here - it connects directly to Sharebuilder and gives me real time data - works a treat!
Ideally I'd like something to do the same with my SIPP in the UK - absolutely ideally it would be the same package or site but that may not be possible.
Anyone found anything?
