There is no REAL price in Forex because there is no centralized market!
Each bank has a buy quote and a sell quote. It's the same when you go to a different country and want to exchange your dollars for pesos, franks, pounds, etc... Each exchange has their prices posted in the window. You shop around for the best deal.
All you need to focus on is the current BID/ASK. That's all that matters to you.
