Major currency pairs all contain the US Dollar on one side – either on the base side or quote side. They are the practically once in a while traded joins in the FOREX market. The majors, all things considered, have the slightest spread and are the most liquid. The EUR/USD is the most traded pair with a step by step trade volume of just about 30% of the entire FX market. I am trading with Eurotrader broker where I get over 100 the currency pairs including gold that I need for my trading.
