"...Someone, an unfortunate soul, just made an error and sold 60,000 e-mini contracts and plunged the market for a minute or so. Now we are back up to where we were."
that does not explain why it went up first, then down hard.
Furthermore the single downticks where all on volume <10k so I don't know why he did not a little more research before posting something that is obviously not true.
