Nice accumulation going back over a year to early 2014. Even when the pps dropped in May 2014, or so, the A/D line remained flat and did not drop along with the pps. It started to rise again in late 2014 just before the pps did, and again, remained flat throughout the pps drop this year. Seems likes it's starting to rise again, ever so slightly. Hmmm.
In a word, "nice picture." (Sorry, that was two words. :-))
