MYEC cannot be shorted. Every Broker will tell you this, unless you put a marging between $ 150 - $ 250 per Myec Stock.
And why MYEC cannot be shorted: Not DTC eligible. And as you said: Ed Starrs does not like shorters, then maybe this is a reason why he is in no hurry to become DTC eligible.
So there never can be a short-squeeze (at least as Long not DTC eligible)
