Yeah, I did find it helpful to test my 4 hour system I like using. It does not offer a 30 min time frame, that was the only down side to me. Also, when trading it you have to find out when news reports came out because you will get sudden spikes in price. But it runs just like if you were trading live but just a little faster. You can set it to 1 min ticks and the candle forms by 1 min intervals. Say you were using a 15 min chart, each candle would open and close in 15 seconds. Ask around some though to others and see what they think about it.
