There is some correlation between cotton and PTA. PTA is the raw material of chemical fiber, but the current trend of cotton mainly depends on supply and demand. Cotton experienced a rapid increase of 10 and a deep pullback of10/year. Now it is still oscillating at the bottom, mainly cotton sales, and the downstream industries are affected by factors such as economic downturn. At present, the turnover and positions of cotton have not been effectively enlarged, and the trend of cotton in the later period is wide. I'm from a futures company, so we can discuss it together.
