looks to me like they pulled the rug on Robin Hood traders who cant trade after 6PM, and are locked out until 9am
so if they chased above $1 thinking this was the next gap play for monday, they got whamboozled, because if there is a gap, most likely it will be in the earlier session 4am-8:30am then take it down to yet again screw RH traders over....
this is another reason why RH sucks and takes advantage of their clients
