I've been having a hell of a time trading. As said, I've seen orders in the book that I try to sell or buy from and they don't go through. I even just had a limit buy order in that showed up on the book, then a minute later a big sell came and pushed right down through my limit buy order. Then I see my limit order is gone and was never even filled. It's like they have those fucking bots jumping in front of you at all times, then when it's not going to work out for them they cancel your shit.
