Bch was just recently modified and then damaged, it seems the guess was right, there is no top for now. The market maker wants to sell mining machines, so they have been pushing the price up recently, but after pushing up, it will still go down. You can refer to zec.

The previous high of bch was 720, and the top is unknown for now, so it's all about trying to short at double.
Since there are no fees deducted after breakeven loss, you can treat it as if you never opened the position, and the impact is minimal.

Regarding the Ethereum order at 3168 yesterday, I entered too early. In the end, trying to preserve the pattern resulted in breakeven loss, so I didn't make any profit. Today, the order at 3260 triggered successfully and hit the top. So, it's the same old rule as yesterday: if you want to preserve the pattern, take a breakeven loss; if you want to trade freely, go for a flat position.
