After yesterday's positive non-agricultural data, the market price rose to 30435, and then started to fall back after rising high. The market trend in this period of one hour is relatively volatile and upward. The short-term pressure is around 30400, and the operation idea is still low and long. It's better to operate. Pay attention to whether you can break through and stabilize the recent pressure of 30400. If you break through and stabilize, the rise will continue. If not, you can take a wave of profits first. The recent support is around 29900.
