Good case for sideways. We first broke 4K back in May last year and have since crossed it many times back and forth. However D and W TFs show a symmetrical wedge converging around 4K. When it breaks out it may be epic.
I don't know how to back test that but I bet some of you guys do, I would be interested to see the results. It is just something that I have noticed over time. It is not totally random.
