Quote from Now is Now:
....In my opinion everything we do , especially in trading, has a "lag" content simply because the brain has to recognise reality to respond.
The alternative in trading is to set pretermined levels to enter and exit, which is, essentially, educated guesses.
Essentially your first statement is correct in a fast market like ES.
In a slower market you may be able to execute on the same tic as your signal but slow markets hold no interest to me and so I cannot comment.
Your second statement follows your first, which is the essence of straight line thinking, but you may chose to re-think "educated guesses"
Essentially by using the latest pattern of say ES and laying a limit stop, you are saying that if price triggers this stop, then I am prepared to risk "n" in order to reap "y+"
I would describe this action as a calculated risk and when repeated successfully it becomes the very essence of day trading.
