If you still have long positions in hand and want to hold on, remember to adjust your stop-loss. The in-flight refueling has already started; at this time, you can set your stop-loss at 3540 to lock in a small profit. If it continues to rise, go ahead and take advantage, but if it drops, then exit. Ensure that every time you open a position, even if you don't catch a big trend, you can't let yourself miss the opportunity. Only after exiting can you have new chances to re-enter! Remember what in-flight refueling and death crosses look like; if you understand them, you will understand yourself!
