July 7 to July 8 cash session is not filled. Where did you get that chart? I does not see the gap he showed in his chart.
You may double check that shortie. From memory, I think he is right that there was a gap. Does your chart contain data in pre-market. Before jobs report market was higher, but at 9:30AM there was a gap (and not filled).
Nonsense. You can buy only when somebody is selling and vice versa. Today buyers were pretty more aggressive than sellers.
