Selling too early always guarantees profit. It's a bit of a pity.

The 3163 order was an all-in trade this afternoon, but I didn't hold on while watching the market. The next one was opened tonight, but I didn't hold it to the end either. If I miss out, I won't open a new position.
During the whole process of pushing up to 3250, I kept shorting all the way up and held some losing positions.
The first time was short at 2840, the price rose about 200 points, but I did some T trading and got back in.
The second time was opening a short at 3050, the price rose nearly 200 points, but again I did some T trading and got back in.
The third time was short at 3163, but it was obvious the bulls were getting weaker, so I went short, didn't exit near 3110, and closed at 3134. That's the first screenshot. The second screenshot shows repeated tests at 3100-3115, with multiple attempts, and the 15-minute chart forming a multiple bottom (a bull trap; before, I would have blindly gone long, but my experience tells me that's most likely going to get hit, so I went short), plus the statement from the "Seven Associations" (bearish), and each rebound was weaker than the last, so I shorted directly at 3121.
Next, let's see if 3000 can hold or if there's a V-shaped rebound. Right now isn't a good time to open a position. I'll wait for tomorrow's movement and then look for an entry.
