#合约 I know that a large number of people come to play contracts with a gambler's mentality, including me. But the only good thing I have is that I have a general trend of the market (not necessarily accurate, but I am sure it will happen with a high probability), and then give myself a relatively large error tolerance interval, which is not particularly large (take ETH as an example) On the premise that the floating price of at least 100+) will not liquidate the position, then start according to the direction you want. In this way, even if there is a loss, there will be some room to adjust. Also, don’t let everything outside affect your judgment, including me.
