Please could as many of you guys comment and possibly rate the following. I am wanting to move my mini dow trading / spread activities to one of these companies. Problem is which one. I need a good trading platform with a really good charting system (dont we all!!!) Please tell me as much as you can if you use any of the following. I only trade the Dow mini YM so if any of you are doing the same I would appreciate your views.
CMC markets
City index
Global trader
Saxo

Thank you

CMC markets - Bad charting and slow. Not good for short term.
City index - Have not tried
Global trader - Have not tried
Saxo - Have not tried, but they seem very good.

Global trader - oh my god just google them to see their lack of ethos - steer clear
IG index is a really great platform!
