For example, the round-trip cost of our soybean meal is only 1.7, and one point is 10 yuan.

The net profit is still 8.3.

So you have to determine the cost first.

In addition, the entrusted price must be determined. For example, there is a difference between the closing price and the selling price.

If you point directly to the current price, it may not actually be a point.

You can write privately if you have any questions.
