Differences of CFDs and Forex. The main differences between CFD trading andForex trading is that CFD trading involves different types of contracts covering a diverse set of markets, such as indices, energy, and metals, whereas Forex offers pure currency trading.
A contract for difference (CFD) is a popular form of derivative tradingCFD tradingenables you to speculate on the rising or falling prices of fast-moving global financial markets (or instruments) such as shares, indices, commodities, currencies and treasuries.

Example of a Forex Trade: The EUR/USD rate represents the number of US Dollars one Euro can purchase. If you believe that the Euro will increase in value against the US Dollar, you will buy Euros with US Dollars. If the exchange rate rises, you will sell the Euros back, making a profit

The main reason why CFD trading is not available to US traders is because it is against US securities law. Over the counter financial instruments, such as CFDs, are heavily regulated through legislation like the Dodd Frank Act and enforced by the SEC (Securities and Exchange Commission).Effectively US citizens or residents are embargoed from trading these instruments and CFD providers from opening or holding accounts for the same. Where US citizens and residents can trade OTC products,such as Margin Forex, they must do so through an entity that is regulated in the USA itself
