I’ve noticed that many people aren’t unable to read the market; it’s just that their position sizes don’t have a “sleeping” ratio: they can’t hold spot positions, and when prices go up a little, they want to sell; once they open a contract, even if the direction is correct, a single spike can wipe them out. To put it simply: first, cut off the positions that will wake you up in the middle of the night. Only keep the positions you can hold long-term, even if they drop 20%, without panicking; if you want to gamble for fun, treat it like buying a ticket to watch a show—accept losing, and don’t use your living expenses to bet.
