First, try to avoid holding positions overnight. Because crude oil investment is continuous for 24 hours, and in the most volatile US session of the market, the domestic market is at night, and it is easy to cause losses by holding positions overnight. If it is inevitable, you must set a stop loss and a take profit price.

Second, the stop-loss and profit-taking price can be set more accurately by referring to the 5-day moving average and the 20-day moving average of spot crude oil.

Third, avoid Man Cang's actions. Crude oil products fluctuate violently, with considerable ups and downs. Crude oil investors can try their best to control the risk within an acceptable range.

Fourth, judging the general trend depends on what happened in the market. There is nothing wrong with drawing conclusions based on market dynamics and following the market. Then be careful when you are in a band.
