It's very possible I'm simply losing my mind due to severe boredom, but over the last few days I've seen more prints go off outside the inside quote on NYSE stocks than ever before. My primary thought is that my quotes are screwed up, but my fills are in line with my quotes. Moreover I'm pretty sure these aren't ECN prints as I filter those out from my quotes. An example was MRK today, all day long prints would go off a dime outside the spread, sometimes the quote wouldn't even be adjusted afterwards to reflect the prints. Anyone else witnessing this?
