One thing on J-Trader... I has NO PROGRAMMABLE HOTKEYS like the way (many) other packages do. (Or at least not when I used it / about 3 months agoo) OK you can bring up a screen with hotkeys but when you need fully customizable hotkeys, don´t go with J-Trader Hope this helps
I currently use J-trader and I totally agree with H20. It seems that he is for real. I'll be shopping around for an alternative platform although J-trader is so reliable that I am afraid to leave it...
