Does your ATS trade NYSE or Nasdaq stocks?

    Which market has better real time quote for taping reading? I found the quote from NYSE can not be trusted. I not sure how an ATS can tell. Sometimes, NYSE will give a big out of range move to get stop orders. This will fool ATS, but will not fool real people.

    Just think about it for a second. Why doesn't it fool real people? Because they have a set of rules in their head that distinguish a real quote from an erroneous one. These rules are not impossible to code.
