The Oct 2017 candle overshot the upper channel line by 127%. Turns out this is the exact distance between the lower wick of the Oct 2018 candle and the lower channel line, where it should have dropped to. This gap (between candle and channel line) was filled by the Jan 2020 COVID flash crash candle. I hypothesize that the previous cycle bull run couldn't continue until that gap was filled. Good news is that in this cycle we touched the lower channel line, so we're on track to moon to 500k without much of a hiccup.
