The day before yesterday, a pin was inserted into the pie, bringing down the entire copycat market. THETA also inserted the needle, the lowest was around 2.1, I stopped the loss around 2.3, and my blood loss was 90%. After the market stabilized, I took the long position around 2.5 and took it back. Although this operation actually resulted in a loss, I think it is necessary. Because when you don't understand the market trend at all, stop loss is necessary. After re-recognizing the trend and re-entering the market, although the entry cost is higher than the stop-loss price, at least you have reduced the risk of a liquidated position. Peace of mind is home.
