I agree, it would make sense the way the bid gets stacked at 16 after so many were being slapped at 17. My guess is channel flipper(s). That or as Teffy said, peeps taking their profits from the trips. But if were sellers flipping out from trips, I would expect a reasonable trader to not stack the ask like this leading me back to channel flippers putting up wall hoping to shake some free for reload back around 13-14. Need someone to smack the crap out of 16 and get whoever it is out of the way so we can make our next leg to 20s and set their new 17-20 channel.
Shorty going down and doesn't even see it coming!!!
