Brockers are just like us as far as the market movements are concerned. They certainly have more analysts, and pretty good analysts, but they are still trying to predict and anticipate market variations. If they find out what will happen, they will quit their jobs as intermediaries, and trade only with their own money. and any broker can find out about the position where it will go up or down, no one knows that where the market will go, this is a fair market and we can trade in this market by understanding and learning on Forex.
