#求助 Excuse me, everyone, how can I achieve fully automated dynamic profit-taking in a contract? For example, when BTC rises to a level I’m satisfied with, I want to set a profit-taking line slightly below the current price. From this moment, for every $100 increase in BTC, my profit-taking line automatically adjusts upwards by $100, and if there is a pullback, I sell immediately at the nearest profit-taking line. How can I automate this process, everyone? $BTC
