Watching the VXX, the VIX ETN, can be quite interesting. It has its own idiosyncrasies, but over the VIX index, this ETN has volume data and charts better than the index on patterns, break outs and break downs.
It appears that there has been a bullish divergence of the technical indicators particularly the VolDiv, and less so on the MACD. Nonetheless, it is clearly observed. Recently, a breakdown out of a range support appeared to fake out the market, particularly when yesterday's candle is rather full, bullish an broke back into the range.
Furthermore, the TD Buy Setup ended and overextended... just waiting for that TD Flip.
Taken together, the short of this (pun not intended) is that volatility is due to return with a vengeance at least to the upper end of the range for a start.
Heads up!
