The real situation is like this. It is not that the master is only proficient in the simple moving average system, but that he "chose" the simple moving average system.

Why is this happening? First of all, complexity does not mean better results.

For example, a set of formed trading system, including confirming trends, entering the market to open positions, stopping losses and taking profits, and fund management. When building a trading system, many people try to make it look "tall" and unfathomable.

It's like when I first made a deal, I studied master Gann's charts, river books, Luotu and so on. At that time, I thought that the origin of the Book of Rivers and Lotutu was earlier than the Book of Changes, and many people had never heard of it. If I can use it to develop a magic indicator that can predict the market, then I may become the god of this industry.

At that time, I wandered around many trading groups and shared screenshots of my research on the map of Horoshu. Many people will chase me and ask, what is this? How to use it? Is the prediction accurate?

In fact, I hadn't worked out P at that time, but I already felt an unusual happiness, that is, "being felt unfathomable" and "being felt badly". I know very well whether it is really bad.

I was immersed in this kind of "being looked up to" emotion and forgot what the real essential demand of trading was.

There is a second kind of person who likes to optimize his trading system infinitely.

Some people, whose trading system has been profitable, also hope that the risk is less, the success rate is higher and the profit is greater, so they start to screen and optimize the trading system.

Would it be better to add large period filtering?

If index filtering is added to the trading system, will the effect be better?

Would it be better if we made the protection rules of stop loss more detailed?

I have tried all the above methods to make the trading system more complicated. Whether it's a lot of duplicate orders in duplicate software or actual combat, adding more filters is not helpful for profit.

However, any trading strategy has its natural decline cycle. Many people think about how to control the decline, reduce risks and greatly increase profits. The result is getting worse.

Why choose "simple"? If a trading system is complex and tall, but unprofitable or difficult to achieve, then why choose such a trading system?

Experts choose a simple trading system because it is difficult to realize and the probability of error is small. Under the same conditions, one is difficult to achieve and the other is easy to achieve, and their profitability is similar. Which one would you choose?

I have always stressed that there is only one purpose for us to do business, that is, to make profits. Instead of pursuing complexity, height, showing off, being looked up to, or the ultimate profit.

However, even if many people know the above truth, they are still unwilling, which is not difficult to understand, because most people have never personally compared the simple and complex trading system, and have no personal experience. All the truth belongs to others.

So, master, why did you choose simple instead of complicated? Because they have tried simplicity and tested complexity, and such attempts and tests have gone through thousands of times, it takes time, experience and money to verify these truths, so there is often a saying circulating in the trading circle: the road is simple.

When you know, natural selection is simple.
