Look at the dollar MACD and index trends in the timeframe after the 2008 crisis, and how that trend was broken to form a new MACD up trend (first chart). See how the dollar went on a massive spike up exactly at the point the megaphone MACD trend was broken to the upside.
Then pan out in the second chart to see the 34 year downtrend in $USD broken to the upside by this new uptrend. Implications of this have to be concerning.
