Last night, 90K couldn't be broken after a long battle, so I closed my position and went to sleep. Now I don't dare to hold long positions overnight, woke up to see it break below 87,000. For now, the uptrend line looks shaky, but there's still some support. For the bold ones, try catching a rebound below 87,000 on the left side. For the cautious ones, wait at least for a 5-minute trend on the right side before making a move.
