$ark fell from around 1.1 to around 0.86 in the hours before the Fed meeting last night, and the pin dropped to around 0.86. I ambushed more than a thousand u (10 times is 10,000) near 0.95, and I lost nearly 800 at that time. knife! Fortunately, the margin was sufficient and it didn't blow up. It accounted for one-fourth of my total position. I warn everyone not to increase the position when the price drops. The maximum is one-tenth. Be sure not to increase the position. That is stupid! Leeks are divided into three, six, and nine grades, okay! ^_^My experience is that the contract is about mentality. I reduced my position at 0.92 and did not increase my position later. As a result, when the Fed increased the bird's call, it rebounded to around 1.0, and I didn't lose much. Finally, I sold it at 1.02, and my position was only 2000u( 10 times), earning more than 200 points! The profit and loss for the day should be the same! Waiting for the next opportunity^_^
