U.S Fed announcement on the 18th

So the U.S Fed is going to announce it's stance on interest rates on the 18/12.. very high probability it is going to be an increase with it impacting all financial markets, especially FX mkts. Going to be the biggest trading day of the year

I'm thinking of shorting the DJI primarily cause of it's volatility, and possibly going long on USD/EUR or USD/GBP. Thoughts? What kind of impact do you guys think is going to happen?
Lets make some $$$!!
