Today I suffered a loss of 70u in a trade, which made me deeply reflect on my trading strategy. When I looked at the BR data in the morning, I should have been more alert than a fluke. I've accumulated enough points to last the next two days, so I've decided to quit for the time being. The biggest takeaway from this experience is that when trading, we must pay close attention to whether the tick chart presents an abnormal straight state. If you find a quilt cover, you must quickly adjust your strategy to get in and out quickly. At the moment I have accumulated 260 points, and with the addition of today's gains, the total number of points brings to 258. Although there was some gain, in order to avoid greater risks, I decided to suspend my trading activities and not continue. Every market participation should be based on rational analysis rather than luck, and being willing to gamble and lose is also a must-have mentality in investment.
