Using the current down from high level measured with direction (up/down) against past history and projected forward to the future gives a date of Feb 2020 for a new all time high.
Down from high chart. The value is shown in read and a version of it multiplied by the time since the last low is in black. This is just for curiosity as a hypothesis that if the market cycles the longer a cycle lasts the more extreme the price value is considered.
Mania using 30 days data. This chart shows the rate of price change in red. When the price goes up at a high rate this chart will show a spike and I use it as an opportunity to sell.
Mania over 60 days.
Mania over 90 days.
Mania over 6 months.
Up from low. This chart in green is supposed to show the relative gain from the past low for each bear/bull cycle. It still has trouble identifying cycle beginnings so the values are not totally correct. This can be used to calculate a hypothetical future all time high price should we see one more bull run. This chart shows a 50X, 22X, 18X and 57X gain over the past 8 years.
