$SOL Trading to make money is really difficult, but losing money is very simple. Making money requires patience to wait for opportunities and to operate at the right points, while losing money can happen with just any random trade, and soon the money is gone. This operation was not very good; 183 is a resistance level. Logically, I should have reduced my position here and opened a short position, but I thought it had broken through. I hesitated for a moment, and as a result, it directly turned around and plummeted, ending the rebound, with floating profits significantly retracing.
