Lmao I want to know how long you been trading too. No surprise that he is laughing at you, and it is also true that you cannot short penny stock, those are for mm for regulating the market.
But yeah, you should sign up for that free course, you may need it.
Yeah, last I checked you aren't a MM and you aren't able to naked short. Only MM's can do that. And that is exactly what you are seeing here. Bring it down, and load the boat, while making some shorting profit along the way, is what they are doing. Once they are done getting their fill they will let it run, but by then a lot of retail will have coughed up their 1's.
