Is it possible to predict what will happen with Forex rates? -

I m into Forex trading. I wonder if there is a way to predict or find patterns in the way exchange rates move. Anyone have any techniques or suggestions? When I feel like getting back into my charts I like to use pivot points, Fibonacci studies and Stochastics to predict price movements and support and resistance levels. The majority of my Forex activity is now based on hedging strategies as a key element of a long term investment focus. Paul
