This is a silly viewpoint. It is silly because it is disempowering; it is admitting defeat before even trying to learn how markets work. Yes, nearly all markets are massively manipulated by those with weight, with the Forex markets being one of the least manipulated because those who would like to manipulate them generally don't have the means to do so.
The important thing to realize is that markets, manipulated or not, are pain optimization machines. They move in ways that maximize psychological distress to to the greatest number of participants, and this happens for sound fundamental reasons based on human psychology, moment to moment supply and demand, and the way in which most people approach a trade-slash-investment. This is often expressed as "markets move because they have to, not because they want to" or "markets move to where the stops are and then reverse". They don't do it because of nefarious secret masters, they do it because that is the natural state of operation of a market.
I strongly recommend reading Mastering the Trade by John Carter - it's one of the best books out there to explain why markets act they way they do in a clear and easily understood way that makes sense to non-traders.
