This first order was made yesterday. Since I was on a business trip yesterday, I didn't find out the first time when Eth broke down. It's a pity.
However, when the first wave fell and stepped back, I basically took an empty order at the extreme position of 1903.64. This point can actually be held for a long time, but since S&P started the rebound mode, it has been watching the market until 5:12 in the morning and took profit at 1841.09.
Although not all the benefits are received, it is the best result to increase the principal in a safe manner. Continue to short ETH after preparing for a subsequent rebound.
Specific data: 1903.64~1841.09 short profit 60U.
