Recently, there are always things happening around 4 o'clock in the middle of the night. For us domestic players, if you don't set a stop profit, the profit will be lost. The highest price of ETH was 2663 around 4 o'clock. Last night, the strategy was long, and the maximum profit was 130 points, but I only got 96 points of profit. Although the difference is not big and it is harmless, I always feel that I have lost something when I see the loss. So if you take an overnight order, it is best to set a stop profit to ensure the maximum profit.
