I can tell you never really traded NYSE.
Reg NMS basically took the NYSE edge and split it up among the main big name firms. Whoever gets the market order with the best NBBO, get to take the rest of it and sweep their own book, ignoring better pricing on other routes. It's an easy arbitrage opportunity, just like the specialists used to do when they would lock up market orders, "price improve" & "provide liquidity" through insane spreads.
Seriously, think about the rule and ask yourself if it makes sense. How in the world is benefitting anyone but the big name firms who handle this order flow. If I send a market order, I don't want it to be limited to only one route. In fact, why should I even worry about where I send it to, I would prefer one single pipeline where everyone's orders are matched. This is what Reg NMS pretends to be, but in fact, it's nothing more than another gimmick meant to line the pockets of Wall Street.
Where have you been in the last couple of years? RegNMS took NYSE edge? You are kidding me... Your dream is your problem, fragmented order flow is the reality, and without RegNMS the picture was way worse for poor investors.
I'm sorry, but I still don't see any single point from your posts...
BTW: I've been tape reading and trade NYSE listed stocks exclusively, and very much familiar with NYSE rules and specialist role in the order flow.
