Over the last three decades the foreign exchange market has become the world's largest financial market. With over $3 trillion USD traded daily it is more than 5 times the aggregate amount of the US Equity and Treasury markets combined.
Unlike other financial markets, the Forex market has no physical location and no central exchange. It operates through a global network of banks, corporations and individuals trading one currency for another.
The markets in the foreign exchange open on sunday evening and close friday evening GMT time. Therefore, you can trade 24 hours a day, 6 days a week.
This means you can trade in your own time, so you are not bothered by closing times like in other markets. The market is there for your convenience.
