Yesterday, I formulated three strategies: a 30-minute central zone of 89600-91500, with the price near the upper boundary in the morning.

The plan is to execute as follows: first, wait for a divergence on the lower boundary at 89600 before going long; second, wait for a pullback after breaking through 91500; third, once it drops below 88000, look for a short position.

In actual trading, I was indeed tempted when I saw the breakout above 91500, and combined with a small sell signal on the chart, I opened a small short position. As soon as the price surged, I immediately realized I was wrong about the direction and decisively cut my losses.

I didn't lose much, but this trade taught me a lot. I originally planned to wait for a pullback on the 30-minute chart to re-enter, but when I checked this morning, the price had already moved significantly.

I got shaken out again. Honestly, I still feel a bit regretful, but I understand—if I want to avoid missing such market opportunities again, I need to continue honing my trading discipline and mindset.
