I added a bouncing line between the high and low , connecting consecutive extreme points. I also chased down a pesky bug in the slope calculation...and for now I have disabled the ability to change resolution basis for extreme detection (e.g. 30m on a 1hr chart).
For fun, I added some shading to make it more apparent at a glance what is happening, but if you find it gimmicky, there's an option to turn that off.
I am inexperienced with pattern recognition, so please send feedback if you have any ideas that would make this more useful.
