I took a small 1/4th position in VXX today. (Tight Stop)(Short Term). Volatility seems to jump up in timed intervals and my calculations are telling me it's soon due. If the S&P500 pushes up next week, I will stop out with a small loss.
MACD crossed bullish today - although not over the 0 line. it looks to be firming though and other charts are suggesting we are near at least an intermediate top in the markets so your timing could be good
