I can't hold spot positions well, and I always think "just open a little" on contracts, then liquidation comes faster than food delivery... To put it simply, position management boils down to one sentence: the part you can sleep soundly over is your position, and the part you can't sleep over is gambling. Recently, everyone has been interpreting ETF capital flows, U.S. stock risk appetite, and crypto market rises and falls together, and I get caught up in the rhythm too, but when it comes to placing orders, I still have to pull back the "wanting to win it all back" hand. By the way, I see complexity as an enemy: only keep two levels—long-term inactivity and small-scale trial and error, don’t create a bunch of tricks to fool yourself.
