Forex Price Cycle

I have seen many times, as if it is like dejavu for me, that prices in Forex market move in a different wave, pattern, or let me say that it draws a certain wave pattern or behavior in a certain period of time (time frame). If in a week let us say that prices tend to move in a channel like direction then that price movement will continually move in that direction unless a certain relevant/significant event may happen either by news, natural disaster etc. In short, prices are predictable. Simply ride on it, befriend with its move and you will gain more with it.
