Reflecting on the events of the past half month regarding contracts. The first time, I started with 5u and reached 1600, then blew my account. The reason was encountering a one-sided rise; I only opened positions in one direction and got it wrong. A few times, I lost two hundred and two hundred fifty. I withdrew one thousand five. The second time, I invested 140u, and in three days, it dropped back to 800u due to a one-sided decline. I still opened positions against the trend and went back to 100u. The third time, starting with 100u, I managed to reach 2150u in five days but then returned to 200u. The reason was greed; I aimed for 2200u and encountered a one-sided market. Once my capital increased, I opened larger positions and did not execute my strategy. Faced with a one-sided market again. The fourth time, I started with 200u and reached 1250u, but yesterday it dropped back to 36u. The reason was the weekend trend, where the fifteen-minute chart was all pins, inconsistent with my trading strategy. I did not strictly execute my orders from small to large. Currently, I have 36u and am aiming to get back to 200u. This time, I aim for 3000u and must strictly follow my strategy from small to large. I cannot just throw in a few hundred u at a time; preserving capital is the most important. Whenever I incur losses, I need to take a break and reflect when I make a profit on the same day. I must follow the market trend and absolutely cannot open positions in only one direction; encountering a one-sided market will lead to inevitable loss. In January, I made 4000u from 500u in two days and withdrew it. I haven't withdrawn much in the past half month. When making money, I must withdraw it; otherwise, I will lose it back. That's about it, recording it for myself.
