Really good but could be better.
I would give this 3.5 not 4 but theres no half star option here.
The main complaint I have is the lack of Candlestick patterns in marketsmith. If this were added I would give 4.5.
The reason for the other .5 off is the inability to just zoom in and out to increase the timeline and decrease the timeline. Sure, you can look at a day, week, month, even minute intervals. However, if you want to look more closely at a daily pattern or look at a weekly pattern from further out this is not possible.
Hope this helps
