Con: it has to learn not to analyze the replays.) It tracks the ball and the players, identifying which team they’re on based on the color of their kits. The lines of the pitch are also highlighted, and all this data is transformed into a 2D map of the whole game. From this viewpoint, the software studies matches like an armchair general: it identifies what it thinks are goal-scoring chances, or the moments where the configuration of players looks right for someone to take a shot and score.
I don't see it as much of a threat to traditional trading though as they are training it by showing it historical games - once it gets to LVGs reign at Man Utd it will probably pack up through sheer boredom.
