tks for those that have replied i have learnt a lot already. should have asked sooner rather than later. i think i am being too greedy and holding too long for eg. i bought $18000 in BUY not so long ago (after reading about it in the australian newspaper on a monday morning) and it doubled in approx 3 days and guess what i just thought "wow this is great" and in no time at all it went back down to what i paid for it without making a brass razoo and to this day is still sitting around the same price...
