The stop loss set here is really not up to standard.
Yesterday afternoon I opened a short position at 84.1, and the market showed no reaction all afternoon.
By evening it finally dropped,
the first wave of decline went down to 82, but I didn't act, thinking it would drop further.
Then there was a rebound, and I still didn't act.
Later, in the early morning, I was about to sleep and set a take profit price for opening a position.
In the morning, I checked, and the price had come down, but the order was gone.

Sigh, setting a stop loss is necessary to prevent incidents like 1011, but the set price must be structurally sound.
