The pain of left-side trading is falling before dawn. Today I shorted RVN, not expecting a sudden surge that precisely hit my liquidation price, and then it immediately turned downward. When the market goes down, I feel very uncomfortable inside. Here I still need to remind myself to pay attention to position management; I cannot take heavy positions, otherwise the margin for error is too low. Also, I need to patiently wait for those patterns that are highly likely to change the trend.
