Now that the NYSE has had their own ECN kinda thing - Direct+ (aka NX) going for a while, I was wondering how people have found it and how it affects their trading.
For example, I know that with the specialist system, if the specialist is short and doesn't want to be, he can put in a big offer on the ask and "scare" some stock in. He'll sit on the bid and cover his short position, then take of his "offer" and the stock will jump up. This is not heresay either as I have witnessed this on the NYSE floor.
So, with NX, it seems like things have changed. For example, I often see 1x1 sizes meaning that the specialist doesn't want NX orders can be executed. So if that's the case, maybe the specialist is doing things different now that NX is here, does he pull the same kind of tricks as he'd be instantly executed and couldn't do any tap dancing? Or maybe now he does that when he actually does want to sell (in the case of my example).
What have other people here experienced with NX?
