When an assets price spends so much time above its average, it can be really concerning when price drops below the average. BUT. Every trend needs a period of time where the price is below it - that's have averages work. It's much better to consider zones or ranges of acceptability rather than a fixed point in time. The channel we are watching for BTC is +/- 2 deviations from the average of the log chart.
If we overlay our signalling indicator on top of the chart, the top of the green cloud is -2 deviations. Interestingly, we can see that as this trend has developed it has consistently respected the lower bound of -2 deviations.
With the correlation (how well 2 variables fit each others trend) dropping below 90%, we need to look for further signs that this trend is in the process of breaking down. Until that happens though, the assumption is that we will again see a recovery off this lower bound and, ideally, return to the upper half of the channel.
