In this chart in addition to the usual KAMA indicator with updated deviation levels I have added a tool that I use to check volatility and/or persistence P and/or growth factor G that I usually publish every January in the annual update (check the blog). It is interesting to note that on the bottom at $3300 gain factor G was externally negative in a similar way to 2015, it could be a confirmation that the bottom has been done on the monthly chart.
