some people get fooled by these 3rd party sites that publish "short data"...there is a HUGE difference between trades that temporarily show as short during the day, but that are covered by end of trading versus 'actual open short interest in a stock'.....
the OTC Equity short report is the only accurate report of 'open short interest' and it is published twice a month.
it clearly shows there is no short interest in ECDC.....
