Macro landscape:
Margin debt is @ Sept '09 lows which means CTA's are not back long yet. Breaching these OCT'18 highs can force them back in. Usually does, FOMO. Next week is Japan's golden week, holiday for most of the country. Reduces participation. Vola is exacerbated in thin markets as algos trip each other. Great for intraday trends. World's central banks have all gone dovish. Safety is U.S. markets. FOMC won't do anything stupid. Be very careful shorting, if your TA says close a short do it.
