My reading was off today, especially that chop in the last hour threw me off. It's kinda late but I had an inkling earlier that HOD would be around 35. But it chopped at 20 and that got me doubting. Ggrrr
I could tell you were off your game a little, that's why I chimed in with "maybe take the next hour off."
Update of the chart posted earlier below. The market seems to have various modes and moods. These last two weeks have been bull mode in hyper drive. While such strength may be rare, it has most certainly happened many, many times before.
