Investors' investment in the crude oil market is nothing more than buying and selling, but it can be divided into short-term operation and long-term operation according to the length of holding positions and the size of profit space. Some investors like to do short-term, and some investors like to do long-term.

When to do short-term and long-term work. This is mainly because investors' understanding of long-term and short-term is not deep enough.

Many investors have a preconceived idea about the operation method. Whether doing long-term or short-term, if you get a relatively large profit at a time, you will enter an inertial thinking and decide whether to do long-term or short-term, which is suitable for long-term or short-term.

The market is ever-changing, big and small. Once investors hold an inertial thinking, they must do long-term operation or short-term operation, which is very dangerous for their future investment career.

Short-term principle and difference principle

"Differentiate" profit, loss and holding time (especially loss) and control it within a few dollars of the price difference. Stick to the post for the longest time, just a few minutes; The shortest, only 2 or 3 seconds. Decisively enter and exit, and never delay holding loss orders for any reason for a long time.

To make long-term investments, investors must first have the following points:

1, it is necessary to judge the trend of crude oil prices in the next few months in advance;

2. Investors should have enough funds for long-term investment;

3. Investors should have good psychological quality, be psychologically prepared and be relatively courageous.

When making long-term investment, we should always analyze the market, don't sell it whenever there is fluctuation, and stabilize it.
