I mainly want to talk about my problems and also warn all you new players. When I made 100 yesterday, I didn't run away and held on. This is the first point. Second, I used too high leverage; with an amount of 600u, my total position of 1500u normally opens at 10 times leverage, but I couldn't pull it back. Initially, I was using 27 times leverage, and I will learn from this lesson. Thank you all for your guidance.
