GTS PRO has completely taken over fxSOL's offer on charting systems as in the past the GTS Pro system already existed - and not very appealing, besides their ACCU CHARTS system. After seeing and experiencing ACCU CHARTS I had no hesitation to open an account with fxSOL ( and have been with them ever since, close to 10 years !)
In my opinion their new GTS PRO is a fancy system, cluttered with unnecessary features - maybe impressive to the newbie - and not practical for tech. analysis - no comparison to MT4 charts, or, best of all, their old ACCU CHARTS. I won't go into detail because the latter seems to have vanished from the surface of the earth and the update I have happily banished from my mind.
All-in-all I think even 1/10 is over-rated.
