$BTC Yesterday’s operations: first, 79688 went long, but it only produced a small rebound. In the evening, when there was a floating loss of 400 points, I noticed something wrong with the trend, notified a small loss of 400 points to exit, and then had it short around 79100. The short position’s low point reached around 76800, floating profit was about 2300 points. I switched positions in time, avoiding even greater losses. Today’s outlook: since yesterday already broke through the box range, the current 77900 is the lower boundary of the box. If it fails to rebound, it will continue to fall; if it goes through, then the 78700–79100 range still needs to drop, unless it regains and stays above 79500, then it would be a reversal.
