Short selling, there is a lifeline below. The reason for 136 is just like this. The lifeline is an important support and resistance. Although it's only a first layer position now, it's still necessary to move the stop loss up after making a profit. That's how trading works. When it's not in the trend, the position should be smaller than when it's in the trend! The rest is for coping. When you go long, you don't fear a drop; when you short, you don't fear a rise. Trading is about reducing the number of losses and increasing the number of wins!
