Stop-loss is really like a breakup, dragging on without admitting it, the more you look at it, the more annoying it gets, and you also have to pay "interest"—attention, emotions, opportunity costs are all taken up. Recently, I've heard some places talk about increasing taxes, tightening or loosening compliance, and expectations for deposits and withdrawals changing, making people more likely to stubbornly hold on, thinking "maybe it will come back if I wait a little longer." My current approach is very simple: if I see something wrong, I cut half first, keep some position as a hope, and don't tie myself to a single trade... The calmness of watching addresses transfer back and forth at night is best also used on myself.
