How to calculate the futures income?

Algorithm example

Example 1, no withdrawal.

Suppose that the initial capital of a contestant is 10000 yuan, and there is no withdrawal or deposit from beginning to end. On the first day, he made a profit of 65,438+0000 yuan, and on the second day, he lost money in 800 yuan.

The calculation results are as follows:

(1) Initial calculation:

Initial account unit net value = initial unit cumulative net value = 1 yuan/copy, initial account unit number = 10000, initial unit cumulative withdrawal =0 yuan/copy;

(2) First-day yield:

Net deposit on that day = 0;

Number of account units on the current day =10000;

Company withdrawal on the current day = 0;

The unit net value of the day =1+1000/10000 =1.1yuan/share;

Accumulated net value of the unit on that day = 1. 1 yuan/copy.

Cumulative rate of return for the day = (1.1-1) ×100% =10%;

(3) the next day's rate of return:

Net deposit on that day = 0;

Number of account units on the current day =10000;

Company withdrawal on the current day = 0;

The unit net value of the day =1.1-800/10000 =1.02 yuan/share;

Accumulated net value of the unit on that day = 1.02 yuan/copy.

Cumulative yield of the day = (1.02/1) ×100% = 2%;

Example 2: Frequent withdrawal of gold.

Suppose there is a short-term speculator with an initial investment of 10000 yuan, making a profit of 5000 yuan on the first day and withdrawing 5000 yuan before closing; The next day, the profit was 3,000, and the gold was 3,000 after the close; On the third day, 200 yuan was lost; The profit on the fourth day is 4000 yuan, and the money before closing is 3800 yuan.

The calculation results are as follows:

(1) Initial calculation:

Initial account unit net value = initial unit cumulative net value = 1 yuan/copy, initial account unit number = 10000, initial unit cumulative withdrawal =0 yuan/copy;

(2) First-day yield:

Net deposit on that day =-5000;

Net profit and loss of the day =5000 yuan;

Number of account units on the current day =10000;

Unit withdrawal on that day =5000/ 10000=0.5 yuan/copy;

The unit net value of the day =1-0.5+5000/10000 =1yuan/share;

The accumulated net value of the unit on that day = 1+0.5= 1.5 yuan/copy.

Cumulative yield of the day = (1.5/1-kloc-0/) ×100% = 50%;

(3) the next day's rate of return:

The net deposit on the current day =0 (Note: since the deposit is made after 15: 30, the settlement has started, so it is calculated on the next day);

Net profit and loss of the day = 3,000 yuan;

Number of account units on the current day =10000;

Company withdrawal on the current day =0 (note: because it is withdrawn after closing, it is calculated on the next day);

Accumulated withdrawal on that day =0.5+0=0.5 yuan/copy.

Unit net value of the day =1+3000/10000 =1.3 yuan/copy;

The accumulated net value of the unit on that day = 1.3+0.5= 1.8 yuan/copy.

Cumulative yield of the day = (1.8/1-kloc-0/) ×100% = 80%;

(4) the third day rate of return:

Net deposit on that day =-3,000 yuan (note: deposits after yesterday 15: 30 are calculated today);

Net profit and loss of the day =-200 yuan;

Number of account units on the current day =10000;

Company withdrawal on that day =-(-3000/ 10000)=0.3 yuan;
