HTML is a relativly new coin which merged Ethereum and Bitcoin technologies and is only traded on smaller exchanges yet.
After the swap from HTML5 to HTML blockchain the prise surged up from 1 to around 40 sat followed by a correction forming a triangle.
The correction currently went to around 25 sat, with 20 sat possible on the support line.
Detailled chart analysis is not possible at the moment, because HTML is yet not listed on exchanges supported by Tradingview or Coinigy.
Rising value and developments could change this soon.
