I have found that FT.com is no longer supporting Vanguard ETF prices. This is a pain, as my Gaier/MS Money software uses FT.com Portfolio for updates.
I messaged FT.com, and they said (basically) that there had been a falling out between Vanguard, FT.com and their information supplier, and so Vanguard ETF prices would no longer be supported. End of.
It might make a difference if anybody affected by this complained to the FT?
