After these two weeks of live trading experience, I am even more convinced of the accuracy of my strategy. Yesterday, I placed an order at 2245.5, looked at it a few more times, and hesitated. I canceled the order, and it could have been filled within a few minutes. In the end, it flew away completely, including the short position from last night. I knew it was a bearish move, and at a high-cost-effective key level, I used leverage. When I woke up in the morning and saw the price was still very strong, I hesitated again. I wanted to close the position. I saw some signals, but I didn't stick to my trading signals. That's my mistake. Later, I will keep leverage within 3+9=12 times. Twelve times is full position. If I need to stop loss, I won't lose too much. The first key level is 3x leverage, high cost-effectiveness (small stop loss). The key level is 9x leverage, fixed operation. If I do it right, the risk-reward ratio will look good. What do you all think? Is the position at the high cost-effective key level too heavy? Mainly because this level is really good. Even if I am wrong, it still offers a chance to break even and exit.
