High liquidity and greater efficiency

Key to any efficient market is high liquidity. After all, as a trader, you want to know that you have an active market with plenty of buyers and sellers looking to participate. Trading volumes in the currency market can be one hundred times larger than that of the New York Stock Exchange, and daily dollar amounts traded in foreign currency approaches $3 trillion compared to less than $100 billion for the NYSE. High volumes and “round-the-clock” trading ensures an active market for currency traders and greater liquidity.

The incredible volumes traded in the FX market also contribute to the integrity of the market—it is virtually impossible for an individual or group to manipulate prices. Compare this to the equity markets, where large price movements can be triggered with no warning should a major holder of a stock suddenly decide to reduce their holdings.
