There are a few patterns on the HUI chart, but everything depends on that bottom trendline you mentioned. I think it holds initially and generates a bounce, but then gets re-tested and breaks. The Feb. lows look like a good potential bottoming area - very strong horizontal support. I'm not a big Elliot waver, but that would fit with the typical ABC correction.
I know all this is just a guess, but I'm going to sell the first real bounce, then wait and see for a while. If my guess is on target, I'll be looking to reload near those Feb. lows.
