This may be unbiased. It's an autobiography of the website owner with references to Delta. Diary of a Trading Loser That's the title he used. It's not mine.

I don't think oanda is odd. Perhaps you should try to detach the charts on Oanda's platform, so you will have independent windows for each charts. You also can detach the dealing rates window to be one colorfull window. cheers... vjr

There are Oanda FXGame, and CMS-forex, where you can have unlimited free demo account with realtime charts. You can create your own setting and memorized your settings everytime you log in, very stable and flexible. Cheers vjr28
