Nothing unique, used the old version (pre stocks etc) and quite liked it. Very simple, but at the time it only had commodities, and was set up very well for them.
The most unique thing about it (at the time) was it actually worked, it kept plugging away, day after day, while metastock crashed, stalled, froze, burned my charts, lost my templates and dont even mention data issues.
Your locked in with their data though,IIRC, and im not sure i like that business model....lots of "cheap" stuff, teasers and lead ins, but if you want all the data, all the stuff (cot etc) you pay a kings ransom for it.
