I have done a number of trades in SPY over the past few years. This ETF has a great deal of liquidity on ECNs, and also trades on NYSE and AMEX. I think that this particular security provides evidence that something is fundamentally wrong at NYSE.
I carefully track and analyze the reasons for any excessive execution costs on a particular trade. This includes careful analysis of time and sales for each available market center. I found that when one of my SPY orders were routed to NYSE by IB's smart router, my resulting executions were at far worse prices than they would have been if they had simply been routed to an ECN for immediate execution. It was my analysis which persuaded IB that it needed to permit each customer a choice to exclude NYSE from IB's smart router. This feature virtually eliminates the unpredictably huge costs which resulted from having my SPY orders smart-routed to NYSE.
Does anybody have a better experience with SPY orders at NYSE? Am I the only person who believes that the case of SPY strongly evidences that something is fundamentally broken and wrong with routine NYSE trading?
