Just to clarify, we are talking about positions that have initially moved in your favour.I sell most, 2/3 if it loses 2dlow, remaining shares if trend drops 2dlow again the next day
More conservative on winners, eg add 30-50% at 2dhighs
Process is everything
I'm assuming that you have a stop in place when you enter the trade and exit your full position if that stop is hit. Or is the 2 day low process your exit strategy from the start of the process.
