In the end, I still couldn't break through and stabilize in the triangular area referenced in the text, and I have completed the irregular slope red arrow in the reference text (the blue arrow is a new marker). There have been many tariff news items in the past few days, the 9th is the expiration date for tariff extensions, non-farm data is released in advance, and the U.S. stock market is closed on Friday. This week is basically meaningless, so I might as well play with short-term trading.
