Today I first went long then went short, I was really too greedy. Originally, I judged that Ethereum would rise from around 2980 to 3240, then move down. When Ethereum broke through 3240 and continued upward, I started to panic, and my operations became distorted. Today I was too greedy, still wanting to gamble on a push higher to clear out a wave before going down. I didn't expect it to fail to go higher, and I couldn't stay alert during the session. With decreasing volume and being suppressed by the moving averages, I didn't switch back to a short position in time, resulting in missing a small trend.
