Because the trading time of crude oil is 24 hours, it is continuously traded all over the world. Therefore, due to the time difference, domestic investment in crude oil only needs to pay the overnight fee, which is equivalent to the storage fee. Whether crude oil is short or long, as long as it is held overnight, it needs to pay an overnight fee.

The overnight fee is settled by the day. The calculation formula is as follows:

The calculation formula is: x days per meal x 0.8 (crude oil overnight charge after 24 o'clock).

For example, if you trade 10 ton crude oil, the overnight fee is10x00.8 = 8 yuan.
