It would seem we come at trading from two different perspectives G.You listen to losses whereas not letting winners run as much as possible or getting removed by some swing ahead of the huge move is the thing that keeps me up at night.
My quits are easy and very low risk. I put in my stops every trade and they stay in until either stopped out or anything trailing method I am using takes over. Simple.Robust.Mechanical.Nothing to consider or tinker with.End of narrative.
BTW G my winners come from outliers so I don't aim for 10:1 or 15:1. My trades have ended profit potential. . .in theory.I don't endure for years. Months are provided that I'm eager to hold profitable trades.
Great trading.
