From the author's experience, complete testing EA must pass through several ways, including:
A. The First step
History market
Well, the next step in preparing other technical things on metatrader, by making a much longer history. So that in testing we will backtest can more freely choose the date, month, and year that we should try to do a back test. So more data history better.
B. Second Step,
Stage Testing
At this testing phase, EA is prepared to do the test. Before the test is done, the user must know the characteristics of EA, EA rule system used, and what techniques contained in the EA. If you already know, you can do the test well. Test the following details are required:
1. back test
In the first way, the EA can be tested quickly on metatrader. EA is tested in a few moments can already diketahi how draw down, how much profit, how much loss is generated, whether or not grap (up / down), or even how many transactions are generated. In other words, use a faster backtest results received by the user in obtaining information from EA. But, back test itself still has its advantages and disadvantages. What are the advantages and disadvantages?
Excess
- EA is able to display the desired information as soon as the user
- Error code, and other technical can be known soon
- Test can be repeated anytime
Shortage
- Not necessarily accurate when tested on account
- Test only at a specified price history user
- The longer the history data, the longer the time it takes to do the Test
2. Forward Test
How to do forwardTest is to use a broker account data, both real account, as well as demo account. Here are the details Forward Test using the account:
Real Account
On this test, the EA must be run using a personal computer or rent a VPS. Minimal use of this Real Test Account is 3 months to 1 year (which is important not less than 3 months). We recommend rent a VPS is better than using a personal computer. Why? The risk of a fatal error occurs using a personal computer larger than renting VPS. Required additional features to measure Forward Test. However, the advantages and disadvantages of Forward Test still exist, including the following:
Excess
- Data is fixed and accurate
- EA thoroughly tested whether or not the system used
- Can know EA gain and actual draw down
Shortage
- Test EA is much longer than the back test
- Server for Test EA must be active 24 hours for 5 days in 1 week
- EA can not be expected to consistently profit forever
Demo Account
Demo account, EA is still recommended to use the VPS. On this account EA continues to run similar to the real account. But there are still advantages and disadvantages in a demo account, including the following:
excess
- Users do not need to use the money as the test material test Original EA
- EA could walk like / just like in a real account
- Draw down, gain, equity, and the balance
shortage
- Data on the demo account a little late on the estate account data (milliseconds)
- Profit from EA test can not be taken, so the performance after WD unknown
- It took longer than do back test
Delivery Server
This test needs to be done because on each broker server definitely has the performance of each on each EA that we will test. This test only as supplementary / complementary in doing Test. Can use a real account or a demo account as a test. If necessary use a test in both accounts (demo and real). VPS uses to keep accounts is recommended. However, many shortcomings and advantages in this test, including:
excess
- Able to detect a good EA is where in server
- Users can determine the speed of data transfer server transaction results EA
- EA produces more profit on a particular server
shortage
- Data between servers have different (milliseconds)
- Execution EA between servers sometimes different (slower)
- It takes a lot of servers for testing Test EA
C. Third step
Stage of completion
At this stage of the EA has been completed in the trial. The necessary data after testing is completed are as follows:
Record Draw down
It is important, the results of the EA considered dangerous or not seen on this way. For the record the test results EA.
Results Profit
Profit EA is required for use in the value of investments which we will do later. Both the poor EA views of how much profit he made.
Results Loss
This information is important for use in long-term investments consider. Information on expected high losses that could still be tolerated and anticipated likely to be found again in the future.
Equity and Balance
If the test results indicate Equity and balance are not together, most likely the EA market could be defeated in the long run. Better to avoid before bad things happen to you.
Gain
This information is important, because as an indicator of the profit that we get later in the form of percent (%), if EA can produce 100% per month, we can estimate the course after 12 months is not it?
D. Conclusion
EA in the assay itself took a test that is more than just a test because:
- The results of the backtest is not the same as the forward test results.
- Results live / real test is not the same as the demo test results.
- Fellow demo / real account was not the same as when different servers.
