I jumped out of my first trade because it wanted to go up.
After redrawing the basic trendline from the 2011 LOW to the 2017 HIGH, I tried the weekly in stead of the 3-daily linear timescale, because I found it weird Bitcoin saw this as just a "small bump in the road".
This was the remarkable result:
Bitcoin went up from the 3-daily based trendline to the weekly based trendline. Makes me wonder if the first top would have been where the daily based trendline would have passed by.
