OANDA has the best mobile app I’ve used to date. I am new to Forex and was looking for a broker that had a nice iPhone app that I could monitor prices and trade. I have an iPhone
I tried “Forex on the go” but ran into lot of problems with errors and you can’t do too much if you don’t pay the $20 a month.
OANDA’s looks really clean and professional. They also let you trade in completely custom lots which is nice when starting out.
EDIT: also just found Trade Interceptor for the iPhone(its free) and lets you draw and plot all of your stats on live charts. You can pull up the EUR/USD 5min and put your EMA and fib right on the chart. A must for the people that carpool and sit in traffic for an hour and a half each way. Traffic just got more interesting.
