Which Forex broker offer low commissions?

You need to be a little careful on this one. Most Forex brokers do not charge a "commission" instead they charge what is called a "spread". You will notice that when you look at a currency pair's price you will see a bid price and an ask price. The difference between the two is the spread. That is what you will be charged when you enter your position. The good news is that this is only charged on the entry of your trade....there is no charge on the exit.
