Hope you don't mind me replying ISA16 Dec 2012 18:22
I have an Isa and a Fund account with HL. I have traded in both these accounts. If I sell something in my ISA I can use the proceeds within 5 minutes on my next stock. I also do this in the USA through my ISA or Fund account. Good luck with your holdings where ever they are. My largest is in MagP.
I think also IMO that dual listed stocks which I have in my ISA are more slow to move, would be interested on your take of this? TPET being one and another is EDGE. Have recently put LRL in my ISA as I feel they have good prospects. As for my one in Caza not happy with that!
