I tend to hold onto spot positions poorly, I want to sell as soon as it rises a little; futures are even worse, a slight tremor in my hand can send warmth to the market... Later I realized a piece of common sense: don't mistake "wanting to make quick money" for "must leverage." Position size is like the weight of a backpack; if it's too full, you get out of breath after a few steps, and if you hit a trap, you'll just flip over. Now I set a rule for myself: only positions I can sleep soundly over count, if I can't sleep, it means it's too big. Recently, the "compound yield" of pledging and sharing safety has been criticized as a copycat scheme, and I feel a bit guilty—anyway, I first separate the core holdings from the tasks, the main line might not win, but at least don't drain the blood bar on the side lines.
