An automatic system may be the solution for many traders who have seen many difficulties manual trading, which, as we know, requires a lot of dedication and hours on the screen, something that most people do not have today, by not to mention the patience for it.
Let's look at some of the advantages of adopting a system of automatic trading:
Let's look at some of the advantages of adopting a system of automatic trading:
1. No need to have experience in trading, especially in the difficult world of Forex. A novice trader can search among the many automatic systems on the market, as well as social trading hubs where many teachers offer their automatic trading systems. The problem with this is that many of these systems or "masters" do not work in reality. You have to know how to separate the wheat from the chaff, but this is easier said than done.
2. If the trade has programming skills you can try to implement them designing many systems and logarithms. The limit is the imagination of the trader, then you can always try millions of different variables, both indicator and time or instrument. If we learn to program or we can even develop our own Expert Advisors (Expert Advisors), so fashionable in the world of Forex.
3. One of the main advantages is eliminate the problem posed by emotions in trading. Anyone who has tried to trading in any way be proven difficult to carry out trading plan once we add the mix of emotions and our anxieties. One thing is to design a system and apply another live. With automatic systems this uncertainty is removed.
4. The problem of time, already named before. In the markets, the number of instruments is so broad and so many possibilities, which can not be glued to the screen for opportunities to give us our indicators all day. You may give those opportunities when we are away from home, either working or doing something. With automatic trading system that we negotiate when conditions are right, whether or not we are at home. With this, there is no need to leave our jobs to try.
5. Opportunity to choose different signals from different suppliers of automatic trading. Thing that can enable us to form our kind of fund or hedge fund, having several providers that can be considered "active".
6. By having more free time because the system handles make trading, we can focus on other more productive things, either designing other systems, such as improving the current, like anything else that can improve our finances or lives.

7. Make innumerable tests of our systems. This is obvious, once we have the chosen system or that have developed. We can apply that system and its variants at previous years and on different instruments if we want. The possibilities this gives us are enormous. However, we must remember that the backtesting sometimes does not match the actual market conditions, which we are here presents the problem of over-optimization. A system can win in "demo" or backtest "but not win" real ".
8. Have discipline. This is related to the point already mentioned emotions. To apply a trading system we need discipline and it is very difficult to get operating manually, because we will always be tempted to get out of the system when our "intuition" tells us. Sometimes you can work out if the operation is winning, but if we are not disciplined and the decision is wrong psychological effects are devastating.

But the automatic trading is not all advantages, but also has its problems and disadvantages. We have already seen some of the advantages they can turn into problems, because there are always different versions in every way we see things, and automatic trading is no exception to this.
One of the problems that usually automatic trading is that this needs to be monitored, because not always enough to simply leave the system in place and go to "sleep" for several days. many problems, such as you have connection problems, we want not negotiate when they get out the news as the NFP Forex, for example, etc. may occur.
Also, many systems require active management in which we should change some of the parameters based on
A key point in the analysis of automatic trading systems is the fact that we tend to over-optimize them, assuming a fairly benign conditions of trading, as if they were always constant, but this is not always the case, because in the long weeks that the market remains open incidents greatly affecting trading conditions, such as those named system failures, especially sudden changes in market conditions often occur. Let's take an example of the latter:
Suppose we do a backtest EURUSD going two years back in time and cost of assuming a spread of 1.5 pips for our study.
It may well be that this system gives us a 30% annual gain, but when applied to real market give us even losses.
This can happen because the system did not take into account changing conditions throughout the week, such as NFP or interest rate decisions of the EU or the US. So, it could happen that a winning trade in our backtest with the 1.5 spread would have given us a losing trade into reality with a spread which increased to 20 pips at the time of the announcement of the NFP. This also can occur in more examples, and night-trading, where there is less liquidity, or unexpected crisis.
In this way, we can make us an idea of the difficulty that the backtest be entirely reliable. Therefore, it is best to have or find a system with a ratio of profitability in backtest above normal. Most often, you have to "remove" part of that performance when applied to normal conditions.
For example, a system that gave us 80% per year over a four-year backtest, might in reality we will give 20%. Therefore, there will always be to look for systems that behave out of the ordinary in "positive" sense in our backtests.
