At first, spot investment in crude oil was mainly used among large institutions, and it was not until the last two years that individual investors were allowed to participate through cooperation with member institutions of the exchange. Spot crude oil is a trading method in which buyers and sellers buy and sell physical oil for delivery in a short time.

Spot crude oil investment generally implements the trading system of T+0, and investors trade more than one order every day. At the same time, leverage mode is adopted to maximize the utilization rate of investors' funds. In addition, its two-way trading mechanism increases the opportunities for investors to enter the market, and also improves the return on investment in disguise. Compared with other investment varieties, the spot investment risk of crude oil is smaller, the market is easier to grasp, and it is suitable for investors who pursue stability.

At present, spot crude oil transactions are mostly between big banks and between big banks acting as agents for big customers. After the signing of the sales agreement, both investors must complete the payment and delivery of funds within two business days at the latest. However, the delivery time can be extended continuously.

Second, crude oil futures investment

Crude oil futures investment is based on spot trading, but its trading method is different from spot investment. The trading object of crude oil futures investment is not the physical oil itself, but the standardized contract about oil.

Compared with spot investment, crude oil futures investment is also suitable for ordinary investors with less funds. Investors can trade futures directly. Two-way trading mechanism, flexible operation and good liquidity are all advantages of crude oil futures investment, but crude oil futures investment requires investors to have enough trading experience, otherwise investment losses will easily occur.

In crude oil investment, futures investment and spot investment are widely used at present. Because crude oil investment has the characteristics of flexible trading mode, high capital utilization rate, perfect market mechanism, irreplaceable hedging function and large profit space, the advantages of crude oil investment are very obvious and it is understandable to be welcomed by market investors.
