IDK what broker you're using but not every is expensive. Could use interactive. IDK what to tell you. But it's easily shortable. Im almost sure Tim Grittani shorted TRTC today. He likes playing TRTC often on the upside and down side.
It is absolutely certain that many here have been shorting TRTC here.
I have no problem with those that do this. They should be honest like some are that they are short.
I would never short a stock with TRTC's potential. Rescheduling Marijuana could be announced anytime and that would create a spike up, and run that would really hurt someone who is short. Longs can only lose their full investment. Shorts can lose 10X or more.
