The half warehouse of 10W is 5W%. 10W deposit means that you bought 50W goods with 5W money.

When the price is 4, you can use 50W to buy 50W/4= 12.5W units of cargo space, and then the price fluctuates from 4 to 16.

You earned the price difference (16-4)= 12 times your unit commodity quantity 12* 12.5W, which is basically the money you earned.

The price at 16 is also 50W, but only 50W/ 16 =3. 125W can be bought.

You also earn 12 points, but because of the small amount of goods you hold, the money you earn 12 * 3.2438+05 is basically a quarter of what you do more.

Therefore, we can't just look at the same profits and buy more goods at low prices.

If you buy less at a high price, the income will be different.
