Did I miss a person coming out publicly stating they entered a sell market order with proof of trade executions? Most likely this would be related to the preferred holder converted shares. With the recent increase in PPS (toward .35) and the recent blip in trading volume, that would allow the holder to convert a higher amount of shares.... just a guess... this tied in with short term momo players exiting that were hoping for gap ups each day till P2 trial news
however the gap at .18 is now filled
the above is all IMHO (consider this my safe harbor statement)
