My call at 8.45am this morning was based primarily on the book build at that time.
If my befuddled memory serves me right I think there was only a 500,000 buy at 18 and then a number of sells at 19. I envisaged that it would open at 18, more buyers would arrive and then it would move up. Also yesterdays volume and price action suggested more was possible.
I called it on the ST Trading competition on 14th April when it was trading at 0.009, so it has doubled in 6 weeks..not bad if you invested onlya small percentage of your capital.
