Soda soda cycle for 4 hours. In the 4-hour chart, I have previously analyzed that the 2560 line is the first rebound support level of soda ash. After the market rebounded here, the daily line closed the big yinxian again, so this bottom will definitely fall through. I am optimistic about the next mid-term decline target in the big cycle. Don't go too far before the trend falls back in place.
