The spread is the difference between the bid and asking price. You will note while trading the currency market that there will also be a difference between the current value of the currency and what you pay for it. That is where the forex brokers makes his profit. That is why they can offer you a forex account for free without any fees. Let's say the current EUR/USD price is 1.27237 and your forex brokers has a 2 pip spread, then you will pay 1.2739 when you buy. You will also note that the spread is lower on the more popular currency pairs like EUR/USD, USD/JPY, EUR/JPY etc. If you go for a non popular currency pair like USD/ZAR you can easily end up paying a 250 pip spread. That means that you will have to win 250 pips before you even brake even.
