Big Brother's stop-loss on this order was done quite well. His stop-loss is close to my opening price, and I also took a loss of 🤔. The stop-loss was set at 92000 because there is a resistance level at 91500 above 91200. Usually, a breakout will lead to a subsequent rise. Since I set the stop-loss, my principal is still intact. As long as the principal remains in the crypto market, I can always return to the trading table. Although this trade resulted in a loss, the trend proved that I didn't get the stop-loss level wrong, so I am still quite happy.
