As we can see the Basic attention token is a rather volatile coin - fluctuating often over 20% through it's trading week.
The BAT has been bleeding out for a while now & took a beating between the BCH/BTC civil war but despite this the 1970 resistance mark that held back the BAT recovery has now become it's support line.
This last 20% rally we've seen in BAT today bought to my attention that this is definitely not the first time this has happened - and these 20% spikes actually appear to be following the downward curved trend line that I've drawn - which looks like a strong ascending scallop is forming.
