One person in the comments tossed out a bunch of symbols (about 150), so I decided to check 'em out.
I'm only a tiny bit through the list, but I took a look at one, symbol NLY, that I had never seen or heard of before. But this graph is something! It's very well traded (tens of millions of shares a day recently), is optionable (with a not-great, but not terrible bid/ask spread) and looks like it's just about finished a monster of a retracement.
I can't believe I had never seen this one before. Slope readers, I think 90% of the value of this blog is from reading the comments, and I appreciate everyone's willingness to share their thoughts and ideas. It's a true community.
