The advantage of the trend strategy is that I stopped at 114,000 and lost all my trading positions, causing me to perfectly avoid this entire period of decline. Although I stopped the loss 6 times before dodging, the loss was heavy, but it was better than holding it until now, so the stop loss is really a good thing, I think many liquidators fell at this step tonight. In the 2 months when BTC fell, all transactions were only to do spot rebounds, and when doing spot rebounds, they also strictly controlled their positions to ensure that they still had bullets to increase their positions when they bought 4w. Rarely go short, unless you see a [channel break-back] structure as obvious as yesterday, and place a short order at 90600, but unfortunately did not catch it, and when it fell to 89600, it looked at the market that was wrong and began to chase short. However, the total principal of the position opened is only a few points, and the bear market can make money. At present, only the fixed investment position is still buying, and it has been half a year since the thunder was beaten, and it continued to buy. The trading system is to have a strategy to deal with ups and downs, and execution is the most important.
