Quote from me1969:
A stop lying at the exchange is alway faster than any trader can pull the trigger (if he can).
Big mistake. NEVER leave a stop on an exchange that is seen by a MM or specialist. It's like giving them a blank check. Sometimes you have no choice, I did that stupid mistake only a couple weeks ago and that stop was purposely hit on a very thick stock called JPM. Should have used the trailing stop, that's a system stop.
They can't run the stops if they don't see them. They can only run levels where stops are most likely placed. That's just part of the game and there is nothing any trader can do about it, the shakeouts have to occur. You can guesstimate the shakeout and deviate your stop enough. Hopefully that can improve the accuracy of your stops.
