Thanks terry91, I'm a bit clearer now on X trades (still haven't a clue about AT Trades though) and I'm happy and a little surprised that so many shares can be sold at, as you put it "top dollar" and there is sufficient support in the institutions to soak them up. If that is the case, it does seem to follow as empirestate says that there would seem to be a platform at with these institutions will buy at and we seem to be there (always assuming that there isn't some reciprocal arrangement to help each other out in these type of situations where a share drops in and out of a trackers fund).
So at present I'm hoping for a bounce but keeping a very close eye out for anymore indication of losing ground. The biggest worry for me is as TimTom2 says the MD trying to wriggle with his statements and when pressed his answers to what they mean.
