Just look from Jan 2015.
SWHC has had a habit of stair-stepping higher, sometimes falling back during consolidations.
You could put that sort of thing in a diagonal but it would be wider than the horizontal channels within the diagonal, and you would have to lower the slope as price goes higher and matures.
Prices at current levels happened last in 2007, and it wasn't there very long, so they don't count very much. Now it's very near an all-time high, and it's likely to be sluggish about making it, which means it probably goes mostly horizontal.
So you could choose your own SR lines while looking at a 3-month chart. From that I see resistance at 22, and first support at 21 and lower support at 20.
Because of the resistance at 22, I don't see it getting back up to 24 very soon in this sourpuss market.
