Yowza, that is a quick little whip snap crackle and pop jump in numbers traded... those are numbers for making a trading income, perhaps some investors are currently "triggered"... Seen this play out a few times before. This is exciting to see... (Always optimistic when in it of course)
Also interesting to note, my refresh rate seems to be a lot slower for OCA atm than normal. Could be a number of reasons, yet I would guess there is a bit of watching going on right now ;)
