$BTC Even if you are optimistic that the trend analysis is correct, you will not wait patiently for the right time. You will place orders impulsively by imagining where the price will be based on your emotions. After placing a profit on the band, you will be greedy and want to eat more times. When the price breaks through the resistance level or falls below the support level, If you don't stop the loss in time, you still try to adjust the arbitrage. If you encounter a big unilateral market like this one, you can only be cut off by the explosion and the loss will be huge. You should follow the order opening conditions to enter and exit the point, stop profit and stop loss, risk control, and be able to maintain your principal. Survive.
