How do you view the theory that review is useless?

I don’t know why you have such an idea. I can only say that in my knowledge, reviewing is very helpful to trading, even greater than you listening to the guidance of a certain trading master.

I think that traders who hold the view that review is useless may just think that review cannot guarantee the consistency of transactions and define the mentality of traders. I really can't figure out why in other aspects.

First of all, let's talk about the consistency of review trading.

Some traders may think that we will be tempted by various temptations in the process of reviewing trading and collecting trading signals. For example, when indicators such as MACD and RSI show opposite signals, this actually occurs. The root of the problem is mainly that you are in a very vague state of your own trading signals. You don't know your trading rules at all, so you will be disturbed.

To put it in more detail, you don't even know how to resume. Reviewing the market is not simply dragging the K-line price, and then entering and exiting something. The core of the review is how you integrate your trading system into the historical market, and let the historical market verify your trading system. Try to simulate the state of the firm offer as objectively as possible, especially when the data is in the market. For example, the data market has given birth to your trading signal. Will you strictly implement it in the process of the firm offer? From this point of view, there will indeed be errors in the results of the review, but this will not become the main point of view that the review is useless. Even if such a situation arises, what is your response? This needs to be incorporated into your trading system.

Secondly, you can't exercise your mentality about reviewing.

In my opinion, it is meaningless to talk about mentality without trading logic. Just like when you go to a casino, your mentality comes from your confidence, and your confidence comes from your capital. If you just play with the mentality of losing and going to work, winning the young model in the club, Then you will never make money. The same is true for trading, when you don't have enough time to review, and you don't have enough time to find out what the market is and how the market will go. Every time you trade, you don't have any support points, and every trade is the same as gambling, which can make your mentality better. As the saying goes, if you read thousands of volumes, you can write with a spirit, and the same is true for trading. If you don’t have enough understanding of the market, how can you develop a good attitude? Therefore, the review is not to exercise your mentality at all, but to let you understand the market better.

In short, review is the way for traders to learn at the lowest cost.
