The monthly level resistance at 180 has been tested, and this pressure has not been broken yet. In terms of operations, keep an eye on the support level at 173. If the four-hour closing does not drop below 173, there is still a possibility of continuation in the upward structure on the four-hour level; once it breaks below 173, you can look further down at the two key support levels of 168 and 160 for subsequent trading opportunities.
