1. At present, the only legal way to speculate in crude oil in China is the account crude oil of ICBC, which we can call paper crude oil. There are four trading products under this project, including North American crude oil in US dollar account, North American crude oil in RMB account, international crude oil in US dollar account and international crude oil in RMB account. Each product includes two operations, namely, buying before selling and selling before buying, that is, two-way trading in the usual sense.

2. The transaction price of each transaction is basically the same as the international crude oil price, but there are some differences in transaction time. The trading hours of crude oil in ICBC account are: Monday 00: 00-03: 00, 09:00-24:00, 09:00-24:00 and Saturday 00: 00: 03. Since we want to speculate in crude oil, of course we should make a profit.
