Brothers, after many days, we encounter liquidation again. These days have been hovering between 60u and 100u. If small amounts can't make a profit, how can we expect larger amounts not to be liquidated? So I suggest everyone still use small amounts to test the waters; just paying a little tuition with small money is enough. If you start with a large amount, that tuition will hurt you beyond what you can bear. Finally, once again, I offer everyone a benefit: the trading insights I've summarized can be taken for free by reviewing past records. I hope it helps you.
