This morning I opened the K-line chart, and Dogecoin suddenly exhibited a fractal on the 5-minute chart. My profit has reached 13%, and I decided to take the profit. The mistake in this operation was not setting a trailing stop loss; I should have implemented a trailing stop loss to manage risk and prevent profit withdrawal. Currently, I am waiting to short at a high point because the long-term daily level is still in a bearish trend, overall still heading downward. So now I am only making short trades on the 5-minute chart, which is also what the Zen master taught. Everything is in the process of learning.
