I really like this app though the individual studies (in particular) need to be a bit more customisable.
Also if I change the time interval from say 5 min to daily I get a window saying 'acquiring data from MtGoxUSD' but it seems to sit there forever and I cant see anyway of getting back to the customised chart I've created. It seems if something breaks in the app you have to create your charts all over again
I also noticed this program uses 20-24% of my total CPU speed. As a result my mining hash rate has dropped 10%
Be nice if these resource issue bugs could be fixed as its a very neat program.
