A buddy who has worked as an EA for five years told me: Any EA with a stable profit on the Internet, any screenshot of a profit is a lie, but I feel that this sentence is a bit too absolute. So how should we choose EA?

EA is to use automation to conduct transactions. It is said that the transaction strategy is written into computer statements, and it is enough to automatically trade by itself.

In fact, the emergence of automated trading is a great improvement, because automated trading can relatively avoid some situations that interfere with operations due to the influence of mentality, and automated trading has a good advantage for traders who manage a lot of accounts and cannot do it manually .

But how to choose automated trading, is it reliable for many people to publicize the results of automated trading? I think it's worth evaluating.

When we see the test results, there are many high-frequency EAs, and this type of automation is generally applied in a small period. The profit and loss of each entry and exit are very small, and the profit is accumulated based on the winning rate. Although I have indeed seen someone come up with the results of running for a year, they are very bullish, not only the retracement is very small, but the profit margin is also very high, which is very attractive. But there may be some unknown things hidden in it. First of all, we need to understand whether the thing he promotes has variety universality. What is variety universality? That is to say, the result of your current test to me may be the result of the backtest of the euro, so what if this is placed in the British pound? What about gold, crude oil, Australian dollars, Japanese yen, etc.? If the final backtest results are all good, or if two-thirds of them can achieve positive returns, it means that this is universal, but if there are only one or two adaptations, then this is caused by the lucky person’s bias It is only a result of the current euro, and it is likely to be adapted to the current euro, and it is very likely that it will not work in the future. You will not make money if you use it. This is a typical means of using parts to cover up the whole.

Secondly, is this universal in time? That is to say, the data time of your backtest is only the last half a year or even a few months. Do you dare to let him run the overall data of the past five or ten years? If the data of the ten-year backtest are all upward overall, then it can indeed be considered further. If the current performance is only good, it is nothing more than adaptation to the current market. In the long run, it may not be so magical.

Of course, the two kinds of universality mentioned above are very difficult to prove, because when you make such a request, people may not agree to it, and they will say that a lot of data is confidential, and you don’t know the core writing method of automation, and you can’t Go and run historical data to verify it yourself, but I think once you show timidity in these two aspects, it means that what you are worried about may just hit its vital point.

There are a lot of high-frequency EAs on the market now, they are nothing more than scalping and grid-based. In my personal opinion, I am not optimistic about these two types, because there are big problems in the logic of their transactions, and the grid is nothing more than carrying In order to ensure a high winning rate, scalpers simply cannot withstand the wear and tear caused by transaction costs due to the high transaction frequency.

Many good EAs actually just write the classic trading concepts into sentences to run. They may be purely to save trading time or remove emotional interference, but this kind of EA performs very well and has high stability. . Moreover, the programming statements of this type of EA are very short, maybe a few lines of code, a few simple function statements, and it is enough to check it regularly once the daily line cycle is loaded. I know of a few that do this. They have been running for more than a year, and they are in very good condition. Of course, they don’t make money every month, but the overall capital curve for more than a year is still rising in a zigzag way, and their automation is It can completely stand the test of variety and time universality.

Traders must always remember that the trading field is not an industry for getting rich quickly. It is just a place where we can earn as much as possible when it is suitable, and control losses less when it is unfavorable. It is not impossible to get rich by trading, but it also requires I obtained it through long-term accumulation and stable output.

Are you satisfied with this answer?

Even the artificial intelligence systems developed by the world's top technology companies cannot be compared with human intelligence. The smarter the AI, the greater the amount of data that needs to be processed. Even if the computing speed has been improving, AI can only be competent in a certain field. For a specific job, if it goes beyond this range, it will go wrong. How many years has been unmanned driving, and I dare not promote it rashly.

EA is not even an intelligent system. Have you ever seen an EA that can talk? for example:

Person: EA, what is the price in Euros today? Can I, handsome and handsome, make money like yesterday?

EA:  …

Person: There are still two minutes for the data to come out. Do you want to place a long order above the current price or a short order below the current price? Hurry up and place an order.

EA:  …

Person: EA, you talk, what do you think?

EA: Fuck, ahhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh.

Person: Who's talking? EA helped me make an appointment with a doctor, I seem to be hallucinating.

EA: Hello? Doctor Hao? You come, yes yes yes, take the earliest high-speed train, the ticket information and address have been sent to your email. It's okay, there's a fool here, I'm going to blow him up later, and you can pick up some useful parts while he's still warm. Okay, yes, yes, yes, you blow up as soon as you walk in the door, I love you.

The advantage of artificial intelligence lies in the processing of large amounts of data, and the advantage of human beings lies in abstract thinking. Humans have ego, superego, and creativity. The machine can only rely on the comparison of massive data to summarize the laws. It can understand yes, no, or, and... But it is difficult to understand that human beings sometimes do not want to destroy the world for themselves, sometimes they die and die, sometimes they are willing to be lovebirds in the sky, and sometimes why bother Unrequited love for a single flower, sometimes a good brother for a lifetime, sometimes a sister-in-law as plump as a dumpling...

Not to mention the understanding of "I don't see the ancients before, and I don't see the new ones in the future. I read the world and the earth, and I feel sad!" This kind of reverence for life expresses more complicated emotions about life.

The data processing capabilities of human + machine, complement each other to maximize efficiency. It's not that EA cannot make money, but it cannot make money under any circumstances. After all, EA is just a simple trading program.

EA can be used to process data and prompt unique trading opportunities, and it is still up to humans to decide how to operate.

EA is actually the programming of a trader's trading model, including target selection, trading direction judgment, stop loss and take profit, position management and risk avoidance, and of course there is a top priority: small probability response!

So what do you think of when you see these? In fact, EA is just an automated execution plug-in for manual transactions! Many people think that their trading logic and trading model are great, but they can't customer service 24/7 monitoring and 24/7 stop loss and take profit, and let a program plug-in complete the above work. However, if you look at the EA you can see in the market, how big is the small file embedded in mt4/5? Do you really think that little thing can turn the world upside down in the foreign exchange market? It is completely impossible for such a simple language logic to deal with the full time, because it still requires a lot of manual intervention in terms of risk control and risk avoidance! Not to mention dealing with low-probability events such as black swan events such as Brexit and the Swiss franc. There are no predictable events, and manual responses are impossible. As an automated plug-in for manual transactions, can he deal with them? Nonsense!

There are indeed many short- and medium-term eas in the market, which can generate good returns or even violence, because the trading model of eas may be just suitable for the operation mode of the subject matter at that time. (For example, the simplest Martin) can be violently profitable and the risk is extremely low. However, once there is a unilateral, it basically ends in a liquidation, because such an EA cannot situationally sense the trend change, and this change requires manual intervention or manual risk control. , To put it bluntly, people still come, right? This thing will only make it easier for you to place orders and close positions in ordinary market conditions. The same is true for the trend ea. It is normal to make no money after doing shocks for a year. If there is a unilateral risk control profit, of course, if there is a reversal, bye bye. Without manual intervention, you will die! To put it bluntly, the ability of EA to make money depends on your good luck. When this EA explodes or loses a lot of money, you did not catch up or have not yet arrived, but as long as you do not withdraw and leave, such EA will always let you game over, not only you but also other people!

No one can predict the occurrence and result of a small probability event, so there is no need for us to talk about that small program to deal with this kind of thing, isn't it?

To sum up: there is indeed no stable EA, even if there is, there is a very strict risk control system that can adapt to the tense, and a high-tech, experienced and high-capacity risk control team is monitoring. After all, it is still manual trading! Don't believe in fully automated active trading ea, it's all deceptive!

After reading the comments, I feel that most people's understanding of EA is very simple, whether it is a shock or a trend, or Martin is a simple stop-profit and stop-loss. The market is either unilateral or a black swan. A really good EA does not allow you to trade all market conditions, but to find a deterministic law with a fixed probability in the uncertainty of the market, and program it, and then only when this law appears Time to automatically trade, of course, there is no 100% thing in the market, this rule is of course probable, but if this probability is in the 12-year history (including the financial turmoil in 2008), there are 80% or even higher The possibility appears, and then supplemented with a reasonable profit-loss ratio, do you think it is very likely that this EA will make money? There is a saying that history is always surprisingly similar, but in the past 12 years, what market has not appeared? Indeed, no matter how good an EA is, there will be a short-term return period, maybe one month, maybe two months, but if you extend the time, you will believe that the profit curve will eventually rise steadily.

I have been relying on EA for more than 2 years to make stable profits, and I can indeed make money while sleeping. If I rely on manual trading, it will not be stable.

Believe it or not

There is a trader behind every ea. The quality of an ea depends first on whether its strategy can really make money in the market? And what is its trading logic? And where is its greatest risk? Most of the eas in the market are algorithmic. The recent market trend does not turn back, and there are naturally countless liquidations. Although it is profitable nine times, only one time will let your funds return to before liberation. Therefore, whether a fully automatic ea is good or bad, I need to understand its trading logic and recognize the biggest risk! Personal opinion! I think net value ea is a better choice. This market is inherently complicated. If you do it with a gamble, the final result will be failure. Stability is the secret to long-lasting trading.

In fact, whether EA is easy to use mainly depends on the customer's understanding of the EA. There is also the customer's awareness of controlling the risks from this trading system. If he has done both of these points well, and then can use it accurately, and understand its risk level, maximum capital drawdown, profit cycle and a series of issues, then he can use it very well.

EA can make foreign exchange trading simpler and easier, and can avoid the emotional impact of traders. However, the offers offered by many commercial EAs, as well as various scams, make it difficult for traders to find EAs that actually work.

How to choose foreign exchange EA?

Since foreign exchange trading is a relatively risky investment activity, if you want to entrust your transaction to EA, you must find a reliable EA. It is best to consider the following factors:

1) Choose EA based on the risk-reward ratio

Each trader's risk tolerance and risk preference are different, and you should choose the appropriate EA according to your trading style and risk tolerance.

2) Test the EA and backtest the historical market data

Backtesting shows us how the scheme works under different market conditions such as high volatility, low volatility, announcements and important news. It also shows possible loss, profit, maximum drawdown and risk reward ratio. We need to backtest each EA.

In addition, usually, there will be some third-party statistics that can indicate the performance of an EA, such as profitability, transaction volume, and so on. These performance data can judge the reliability of an EA.

Before the official use, traders should also use a demo account to verify it. If it runs for a period of time, there are no mistakes and the declared profit rate is reached, then you can try to put it into real operation.

3) Learn how the foreign exchange market works

Most fraudulent EA providers target foreign exchange novices, because foreign exchange novices often have unrealistic fantasies about foreign exchange trading, imagining that they can get rich quickly, so they are easily attracted by the hype profit rate advertised. However, only if you master the operation mode of the foreign exchange market, you can avoid being fooled by EA suppliers and discover danger signals in time.

4) The credibility of the system

Before deciding whether to choose an EA, we need to conduct a comprehensive background assessment of it. If an EA provider claims that the EA is capable of generating good profits, you can check to see if these claims have been verified by an unbiased third-party website.

In addition, you can also choose based on user reviews and recommendations, and EA's running time (ideally should have at least a few years of running experience), user usage, developer qualifications, after-sales solutions, etc., need to be carefully considered. verification.

Summarize

While there are many benefits to using an EA in forex trading and can analyze millions of charts faster than a human can, however, remember that no strategy, no tool, no system can guarantee 100% success.

Successful trading requires a lot of research and experience. In addition to using effective foreign exchange EA, the most important thing is to continuously increase your trading knowledge.

Yes, I can tell everyone responsibly that there is a good EA, but you probably won’t see it. I don’t need to say the reason, and the transaction is anti-human. The thinking logic of a good EA may not be understood by ordinary people. , because many of the theories we learned from the Internet are wrong, so it must be incredible to understand in a wrong way, such as the number of hands, positions, etc.

EA is not unprofitable, but it cannot be sustained and stable! For those who live in the market, EA is dead! This makes EA unable to respond to market changes for a long time. The EA of many large companies is not a static strategy. They will often make adjustments and corrections according to market changes. There will be a continuous maintenance, and this EA is a company secret. , they are not for sale. Think about it, who would sell a cornucopia that can make money?

how to say! EA trading has certain advantages and can reduce time costs. However, EA has not been widely popularized at home and abroad. There must be its own reasons. Avoid some bad trading habits, but at the same time, it also curtails the opportunities for traders to be flexible and adaptable. Professional programmers cannot cope with various market conditions. How much can some codes form EA?

everything has two sides

Coincidentally, last week I turned the system into an EA, opening positions, protecting capital, and stopping losses. These three links are handed over to EA. I am only responsible for taking profit and dealing with loss orders.

After three days of modification, she changed all the situations that would be encountered with a high probability to ea and let her handle it by herself.

Now I find that the first two years were really stupid, but now it’s too fucking easy, the office computer is not turned off, and the ea will send me an email to remind me when processing the list. If you want to deal with it, turn on the remote control and replace the corresponding ea, don’t mention it How cool. 😂😂😂😂😂

As for what you want is a ready-made ea that does not require human intervention, let it help you make money by itself. For the time being, it is unrealistic, the uncertainty of the market, the fault tolerance rate of your funds, etc., must be understood by yourself. If you have enough funds, Martin can just run around 😂😂 and the ea is not your own. If you don’t understand the principle behind it, if something goes wrong, you won’t be able to deal with it. What’s the point? A lot of time in trading itself is dealing with errors...

Choose EA, don't be blind. Fully automatic EA is generally not advisable.

Fully automatic EA is not flexible, and pure manual is a bit backward.

You can create a semi-automatic trading system that suits you according to your own trading habits.

It is very difficult for EA to adapt to all the unilateral market fluctuations. It needs to add artificial risk control to make up for it. There must be awesome EAs, but they are generally inseparable from artificial risk control. In the future, the writing technology of EA will be better, so it is hard to say look forward to

Although most of the EAs on the market are scams, there will still be good EAs, and you can't knock down a boat with one stick, but good EAs are not so easy to find. This depends on chance.

The credibility of profitable screenshots is really too low, and the cost of fake screenshots is too low, as long as you know some simple photo editing software, you can basically make them.

When choosing a good EA, I personally look at it like this:

First of all, it is to look at the overall strategy, which is the idea of ​​the EA author, to see what his perception of the market is like, and whether there are any logical mistakes. At least the trading philosophy must be relatively correct.

Secondly, look at EA's risk control and its means. A good EA, its backtest must not be too high, nor too low. It is easy to understand if it is too high, why is it difficult to understand if it is too low? Basically, the EA with a very low backtest has a high probability of being a Martin strategy, doubling and increasing positions against the trend. As long as it encounters the current gold and gold market, it is difficult to survive such a sharp rise in the market. This is The biggest risk point of this type of EA. There is no problem with its operation a lot of time, but once there is a problem, no matter how much profit you made in the early stage, you will lose it back. Because you don't know when the market will go out of the trend.

Finally, it is to see its profit. It is not enough for a good EA to have a strict risk control system, it must be profitable, otherwise it can only be doing useless work.

These are my thoughts on EA.

An excellent EA must be verified by the professional market. Before an EA is launched on the market, it must go through at least 1 million transaction debugging before it can stand the test of time. Slow bull ups and downs and a wave of black swans can make most traders tremble. It is the best praise for both traders and EAs to remain calm in the face of bad situations. Therefore, a good EA must have its own preventive measures against the black swan market. It does not seek 100% avoidance, but it must also have a certain filtering ability.

At the same time, he must have the ability to stabilize profits. A business that earns 10 yuan and loses 100 yuan is not worthwhile. He must have stronger profitability or potential. Strong profitability is itself a kind of risk confrontation, and only in this way do you not have to be afraid of losses. However, the lure makes the mind dizzy, too many people brag about their EA systems in order to make money, digging traps, and too many people trust others with daydreams and fantasies. On the market, most of them simply apply the Martin system, use small stop profit and anti-risk methods to increase profitability, thereby creating the illusion of EA's stable profitability to attract investors. In fact, hidden risks. There are also some people who use the method of observing account fraud to deceive investors. This incident was shocking for a while, and it also made a certain platform a street mouse, and a certain beautiful observation account was revealed to the world.

It's not that there are no good EAs, it's just that there are more fools. Everyone, please be sure to keep your eyes open, stay rational, and know that risks must exist! A set of EA must have its weakness. What we need to know is, is the probability of this weakness being triggered high? Are the consequences serious? Is his advantage enough to cover it?

First of all, investment is risky, and no one can guarantee 100% profit. But if you want to maintain stable income, EA is better than manual labor. EA is a tool that can improve the accuracy of investors' order placement and increase the efficiency of income. Of course, whether the tool is good or not depends on how you use it.

There is nothing that can make a stable profit, whether it is manual or quantitative, it can only be said that the future is unpredictable in a period of time

Any screenshot is an afterthought, so it will be very beautiful. If it is not beautiful, it will not be shown to you. If an EA that can take all the market conditions is a money printing machine, who will sell you the money printing machine? Therefore, even if there is an EA that can make money, it must be operated by a person who can make money. It is up to people to judge the direction of EA operations and filter out noises. Does words matter? It's just a tool to do it for you.

If you buy and sell something, if you use a set of dead programs, you can set a certain point to make a profit if you buy at a certain point, and you will definitely lose if you sell at this point.

I have seen several colleagues engaged in EA, including my younger brother, who later changed careers...
