Yesterday's plunge raises the question of whether to cut losses; today's rebound of 10 points prompts the question of whether to rush in😂

They say to reduce the rebound resistance level slightly when fully invested, and to gradually add back during the previous plunge when reducing positions, but upon waking up, I see the questions:

Should I liquidate for profit, and then short? Is there no adjustment? Will it go up directly? Will there be a third wave?………

It's really not easy to stay firm in my own rhythm and logic amidst such chaotic information.
