The method of stop-loss is not as good as opening a new hedging position, because a stop-loss is equivalent to leaving the market. Opening a new hedging position does not mean leaving the market. Once you leave the market, losses truly become losses. Floating profit is not a win, and floating loss is not a loss. As long as you do not leave the market, there is no real loss. A hedging position modifies past incorrect decisions with new correct decisions. Incorrect decisions that have been validated by market trends need to be corrected in a timely manner. Holding on to positions is just repeating the same mistakes.
