I have used Oanda for a couple of years now. I have a couple of bad memories but 99% of the time they have been great.
Their fxTrade platform is the best platform I have ever traded on. It's fully customisable and user friendly.
Yes... and Yes!
Swing trading on 4 hour charts. I have never tried trading Gold on a smaller time frame.
Gold has been one of my biggest earners so far this tax year - very pleased.
Perhaps I will post some photos shortly.
