The top 12 expert advisors have executed 361 trades total with summary output of 6353 points.
All the expert advisors in the website have good backtest results. Now they are running on demo and they are performing their out of sample check. This is the ultimate way to determine if an expert advisor is wining by luck or is adjusted to the price curve. Even if this realtime resusts are good, there is no guarantee that the expert will have good performance in the future, but good results in demo is good indication for that.
Why do i need a forex trading robot?
Probably if you are new to the forex market you will ask this question. Maybe you think that the human brain can process the chart information better and make better forex analysis and decisions about the possible market directions. Well... you are wrong. The forex market is unpredictable as the most things in our lives. If the market becomes predictable, it will stop existing. Then what can we do? We can monitor and find specific market situations after which something is happening. Of course, you will never find such case in where after A follows B in 100% probability. But you can find a 60% one. And this will lead to developing a forex trading strategy and when the strategy is crystal clear, it can be coded into expert advisor.
How to choose the best expert advisor
No matter how many stats you watch, no matter how good the equity curve looks, you never know how it will perform in the future. It is possible that an expert advisor that has medium results, to be much better than the expert advisor with the best performance now. Let's say that a good looking expert advisor has a 60% chance to be also good in the future. So if we choose 1, from which it will be - from the 40 loosing or the 60 wining? Again... we don't know. But the bigger portfolio of experts we make, the closer we get to that 60 -40%. What if we monitor closely the things and shut down the bad performers and substitute them with better expert advisors? Then we can reach 70-30 or even higher.
Why the EA can stop working?
As everything around us, the markets change too. The swaps change. Economic results change. Market volumes change. Trends are becoming bigger or smaller, ranges are becoming wider or thinner. The forex expert advisor is designed to work within some specific market parameters. When they change beyond a certain limit, the EA will stop working as expected. Usually, this doesn't happen right away but like a process of constantly getting less and fewer profits. We must be prepared that all the expert advisors will fail at a certain point and the questions are not if, but when.
Lifecycle of the automated trading systems
There are many types of trading systems and many lifecycle models but the one we choose has tested, out of sample test and trade. The test is the largest period where we test our rules. It must be big enough to get enough trades for good stats and not so big, because as we said in the previous paragraph -it can be close to its end or have bad backtest results just because we are including different market conditions. For example, 10-15 years ago we had 5-8 points spread on EURUSD, now we have 0.8. If we test on such old data we will have good results wich are not real. We have chosen that backtest period to be close to 2 years. The next important period is the out of sample test. In this test, we verify that the system still have the same performance parameters as in the test period. If the system can pass that period it is ready for trading. In the most common case, we have 2 years backtest, 6 months out of sample test and 1-year trading.
