"When you Download BetTrader Evolution you will automatically receive a 7 day free trial of the full version. When your free trial of the full version runs out you can continue to use BetTrader Evolution in limited mode for free for as long as you want. The only difference between the full version of BetTrader Evolution and the free version is that the free version only updates once every 5 seconds. You have full use of both the grid and ladder interface for free, as well as the bet placement tools. Training mode is not available in the Free Version."
