HLS is a bit of a punt. It has been rising strongly since last March and shows no sign of reversing (although it must at some time).  Price has broken above resistance at $3.95 and while it has fallen back last week to the lower boundary of the the rising price channel, that boundary is a level of support that price could bounce up off from. Price has also made a Wyckoff pattern (the shaded rectangle) which says price should make higher lows and highs (which it has been doing) until a price target of about $3.65.
