Superior Liquidity

With a daily trading volume that is 50x 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. Traders can almost always open or close a position at a fair market price.

Because of the lower trade volume, investors in the stock market are more vulnerable to liquidity risk, which results in a wider dealing spread or larger price movements in response to any relatively large transaction.
