What exchanges allow margin trading?

[Nathan047]

So, as the title says, I’m looking to lose (not intentionally, but inevitably) a few dollars margin trading. I asked this recently, and since I am from the state of NY I can’t use some of the big exchanges so I specifically asked for exchanges that allowed NY residents to register and margin trade. Since I got no replies I’ll ask again, but instead please just list all exchanges that allow margin trading and I can do my research as to whether I’m eligible to join.
