IMO, the market is only non-random due to trader herd-mentality. Everyone using the same software, same algorithms, trend-analysis, etc. If everyone's software says that this particular point is a resistance/support level, then the market will potentially move because of this. But this strategy of waiting-for-the-dumb-traders-to-make-their-move has been practised for decades. But a single random event will invalidate all this herd-mentality in a second. And plus, from your Wiki link, it states: "[Simon's] models are based on analyzing as much data as can be gathered, then looking for non-random movements to make predictions". I don't see that as being earth-shattering considering that random events occur constantly. And how do they know the movements are non-random?
