I've seen many people say you should have your exit strategy planned before you ever make the trade. When you are at the tail end of a trade where your pre set exit is in sight and the candle is going long and looks like it has no plans on stopping, or the moving average is trending sharp and vertical, is there ever a time where it is okay to deviate? I suppose one might argue deviating here or there, even if it works out is -ev over the long haul and reinforces bad behavior, but I'm curious if people implement certain grey areas for the aforementioned scenarios? I've also seen it said "Be patient with your winners" which makes me curious if people move the goal post when they see certain conditions setting off bells. Thank you in advance.
