Suddenly thinking that to make contracts you should first learn how to be trapped. Why do I say this? I don't know if you've noticed, but every time you get trapped and see that floating loss increasing, you become more and more anxious, and the more anxious you get, the less you know how to operate. Then a series of blind operations bring you closer to liquidation. So the premise of learning to get trapped is being able to read price points, control positions, add orders, set stop losses, and open hedges. Each point can be studied in detail.
