Anyone familiar with using the Slip to get short? I hear it's pretty expensive, but how does this actually work. I'd like to know how much it will cost me to use the slip order.... and when do people usually use this as a way to get short? One day i used slip 4 times and it ended up costing me 19 bucks or so worth of fee. If anyone could give me a low down on this i would really appreciate it.
