i made the Gann start and end points at about the 2015-16 time, drawing the bottom Gann line as the bottom level trend for BTC
and zooming out gleans some interesting levels
that initial trend line sits at about 1800 usd right now :p
I have to say the Gann fan intrigues me.
you can get alerts if you draw trend lines over the Gann lines
goodluck
