PTA: Crude oil support, the medium-term continued to be over-treated, but the spot is weak, and long positions and positive positions need to pay attention to position control. The spot market is slightly weak. The current PTA processing fee is around 890 yuan/ton, and the profit is relatively good. Benefiting from the pressure of PX's accumulated warehouse expansion, the PX processing fee is only 179 US dollars/ton, and the profit will be transferred to the PTA factory. In terms of supply, Yisheng’s 6-million-ton facility that had a short-term shutdown recently restarted, and the 2.5-million-ton facility in East China restarted, and the start-up rebounded. Around 80% of the overall polyester load. After the price increase, TA transactions were relatively weak, and the market acceptance was average. The polyester factory entered the market to sell PTA, and the momentum to continue to rise in stages was slightly weakened. However, the remaining polyester factories have been prepared for approximately 2 weeks, and there is still an expectation of just-needing purchases in the future. Inquiries for orders in the terminal weaving link have begun to increase, and the market is worried that the prices of raw materials will continue to rise, and the transaction situation has diverged. Driven by the cost and supply side, TA prices are expected to remain high, and there is a short-term callback risk. Pay attention to position control. Hold long position，long PF short PTA.
