Many stock traders started to trade currencies instead of trading stocks of individual companies because they see this market as having greater leverage, sophisticated software and strong market trends.

A greater leverage allows traders to control larger positions with smaller amounts of capital.

Advantages of trading Forex:

• 24 hour trading
• Superior liquidity
• No commissions
• 100:1 Leverage
• Profit potential in falling markets

The Forex market is so liquid that there are always buyers and sellers to trade with. The liquidity helps ensure price stability and narrow spreads.

The liquidity comes mainly from banks that provide liquidity to investors, companies, institutions and other currency market players.

The fact that Forex is often traded without commissions makes it very attractive as an investment opportunity for investors who want to deal on a frequent basis.

Trading the major pairs is cheaper than trading other cross because of the high level of liquidity.
Since the market is constantly moving, there are always trading opportunities, whether a currency is strengthening or weaking in relation to another currency.

When you trade currencies, they literally work against each other. For example, if the EUR/USD declines, is because the US dollar gets stronger against the Euro and the other way around.

If you think the EUR/USD will decline(which means the Euro will weaken versus the dollar), you would sell Euro now and then later you buy Euro back at a lower price. In case EUR/USD indeed declines, then you can take your profit.
