Personally, I believe EUR/USD is a fantastic pair which you can begin with. If you prefer, you can exchange GBP/USD, USD/JPY, and USD/CHF. It is great for you to watch the price movement live, and find out how it react to this news and feel the heartbeat of the forex market. The fantastic time which you can do this is from around 3am to 12pm EST because it transfer quite abit. I live in Hawaii, and it's difficult for me to watch the market throughout the evening.
