Dollar longer-term trend is being challenged by current FED super dovish policy. Remember there are other central banks as well which are also struggling with the deflationary environment and may use negative interest policy. Which will eventually give strength to the dollar.
Remember the Stock market is forming a bubble especially TEC SECTOR. If this bubble bust then USD will fly without any stop. If the stock market bubble bust then we may have liquidity problems again.
So watch for a bounce off and look for the dollar to gain its King currency status.
It's a longer-term analysis so don't be critics to early.
