During the first profitable trade, I didn't decisively close my position. Instead, I chose to sell in batches, aiming to lower my cost basis and hold with zero cost. However, when the trend reversed, I mistakenly thought it was just a rebound and even added to my position during the reversal. After finally closing out, I went to chase highs at point C and got stuck. Lately, I've been wanting to train myself to watch the market and identify trends, but I have no clue where to start. If I could recognize my own limitations, only take limited profits within what I understand, and sell when there's a profit without fear of missing out, perhaps the outcome would be completely reversed. For the first trade, I shouldn't have chosen to hold the position in batches; maybe I could have caught the reverse trend. But being trapped affects judgment. Perhaps my analysis knew the trend had changed, but emotions prevented me from acting, lacking calmness and decisiveness. It's all very confusing, I don't know where to begin. I don't want to give up, but I truly feel at a loss. Sigh!
