Martin, If you were to read what to expect in the beta it had trading listed as such..............................."The trading AI in particular is very much a work in progress. We try different things, sometimes it gets better, sometimes it gets worse. It wasn't that awful a couple of weeks ago, but in the last few builds...well, on a scale of Mike Milbury to Sam Pollock, right now it's at Rejean Houle." Hope this helps mate.
