I have 1 yuan coins in my hand now. If I throw them out, I will earn 1. 1 yuan, and in turn I will lose 1 yuan.

100, 54 heads and 46 tails.

In other words, the positive probability is about 54%.

My income is 54 *1.1-46 *1=13.4 yuan.

But I seriously doubt that I cheated, because I didn't have the initial strength when I finally threw it, just throwing it casually.

But at 42-49, I threw the reverse eight times in a row, which was the longest loss.

So, later I simulated the probability of 5000 times with software, and the number of positive times was 2534, with a probability of 50.68%.

The reason for doing this boring experiment is to get the following data:

1. Revenue expectation;

2. Average, median and standard deviation of monthly income;

3. Average, median and standard deviation of weekly income;

4. Average, median and standard deviation of daily income;

5. Sharp ratio of monthly, weekly and daily income;

6. The ratio of profit days to loss days;

7. Cumulative transaction amount;

8. The most profitable day;

9. Days with the most losses;

10. Maximum loss amount;

1 1. Continuous profitability;

12. Continuous loss statement;

13. The proportion of funds with the largest loss;

After getting the above data, I found that it might be better if I threw a coin while lying down!

Throw it farther, but you lose more!

This is also the reason why most retail investors lose money.

It is because they will not do some repetitive and boring things, that is, they will not statistically analyze their trading data.

They focus on prying and paying attention to unimportant things.

However, I forgot that the return of a person's portfolio is determined by either increasing the return rate, increasing the probability of return, or both.

How to do this depends on your past transactions.

Whether you hold funds, #ETF# or stocks or futures, the result is the same!
