Liquidity

With a daily trading volume that is 50 times larger than the New York Stock Exchange, there are always broker/dealers willing to buy or sell currencies in the FX markets. The liquidity of this market, especially that of the major currencies, helps ensure price stability. Investors can always open or close a position, and more importantly, receive a fair market price.
Because of the lower trading volume, investors in the stock market and other exchange-traded markets are more vulnerable to liquidity risk, which results in a wider dealing spread or larger price movements in response to any relatively large transaction.
50:1 Leverage to 400:1 Leverage

Leveraged trading, also called margin trading, allows investors in the Forex market to execute trades up to $250,000 with an initial margin of only $5000. However, it is important to remember that while this type of leverage allows investors to maximize their profit potential, the potential for loss is equally great. A more pragmatic margin trade for someone new to the FX markets would be 5:1 or even 10:1, but ultimately depends on the investor’s appetite for risk. On the other hand, a 100:1 leverage would be the foremost suggested margin trading to use for the best risk and reward return.
