First, control positions. It will be safer if the position is controlled between 5% and 10%. If you are not sure, try not to exceed 20%. It is best not to operate in Man Cang, unless you are sure of 100%, otherwise the loss will be very serious.

Second, determine the direction. Generally speaking, it is necessary to take advantage of the trend to make overnight positions, and follow the current trend. If it goes against the market, it is best to close the position within one day, and closing the position overnight will increase the risk.

Third, choose varieties. Actually, this is very important. A. Some varieties fluctuate less in one day and often jump the next day, such as copper. If we can find the right direction, the income of overnight warehouse will be more than that of intraday operation; B. For some varieties with small intraday increase and continuous trend, due to frequent operation, the handling fee will increase, and at the same time, the income from intraday operation is less, so you can consider overnight warehouse, such as agricultural products.

In short, follow suit and control positions.

Good luck!
