To pause the tester and enter a trade you need to click around the speed scrollbar. The Stop button fully stops the testing process and you can run it only from the beginning. The latter drawback ruins all the benefits of testing indicators. A trader can only see the chart being drawn and the indicator working, but cannot put orders. There are no troubles with testing integrated indicators, there are sometimes problems with testing added indicators.
The function of indicator testing was added to MT4 a few years ago. If the indicator had been designed before this function was added, the tester may fail to run it. An Expert Advisor is tested almost in the same way as an indicator. MT4 has a built-in editor, MetaEditor, where you can write the code of the trading robot that will be accurately synchronized with the platform.
Testing here also starts with importing the historical data. Open the tester and in the box, where we chose Indicator in the previous example, you now select Expert Advisor. All the rest parameters are similar to testing an indicator, except for the Expert properties. In the Inputs, there is a Download button that facilitates setting the parameters.
When you test one robot on a single currency pair and you have basic parameters, they can be set manually. But when it is about a robot with 10 settings and more especially about multi-currency Expert Advisors and about testing on the dozens of assets, one can easily be confused.
So, robots are usually supplemented with files that have the. You just need to upload these parameters. Press on Start button and see the chart. I should note that when you test an indicator, trades are not entered on the historical data, in this case the robot puts orders itself. Until this date, testing will be passed without visualization without chart , but the trades will be included in the report. At the bottom of the platform workspace and the tester as well , there is the menu, where you can see the statistics; I marked it with the red box in the screenshot below.
I also want to stress that this screen presents the testing process for an Expert Advisor, based on Moving Averages. You can see the trades being entered, exited, quotes and the reasons for exiting. The box above the tester, where you can see the balance amount, is the box for current transactions that you can execute together with testing in the next tab. I suggest you start analyzing with the Graph tab. If the equity curve the balance curve is clearly descending, with sharp jumps and deep drawdowns, go back to the Expert properties and configure the parameters.
If the Expert Advisor has entered no trades at all, there is some error. Look for the error code in the Expert journal, the description is on the mql4. The Results tab presents the testing results. Bars in test. This is the amount of the modeled history data in bars;. Ticks modeled. It shows the amount of the modeled ticks. Each sequence entry is a bar state at a particular point in time.
The number of bar states may vary depending on the timeframe, the quality of quotes. In theory, the more ticks are modeled, the more precise is testing and the longer time it takes. In practice, there are situations when a detailed run is a waste of time, since the results will not differ from a faster testing mode. Modeling quality. It is the quality of ticks modeled during testing in per cents. If you want to learn how to improve the quality of modeling with this software, write about it in the comments.
Mismatched chart errors. Errors appearing when ticks are modeled in different timeframes. The most frequent reason is the difference between the data from the history center and the quotes provided by the broker. Modeling quality is schematically displayed as a band in the next line of the report. This band can be of one of four colors:.
At that, the brighter the color is, the better in quality the modeling was, as there were more data of the shorter timeframes available. If any part of the band is grey no data available , reload all the historical data.
Other parameters are trading performance; I described how to analyze it in this article. This backtesting report can be copied to the clipboard or saved in the hard disk as an HTML file. To do so, one has to execute the "Copy" context menu command or that of "Save as Report", respectively. Backtesting can be saved not only in HTM format, but also in Excel or other programs that can automatically group data using a given algorithm and output statistics in a convenient form.
For example, in the form of diagrams and graphs. This is convenient when you compare multiple trading systems or several combinations of parameters for one system. In addition, backtesting results are used for personal purposes. For example to illustrate the efficiency of a trading strategy when one wants to sell an Expert Advisor or to attract funds for trust management.
Features of a fake backtesting report:. If anyone offers you to invest in a trading system and shows you a backtesting report as a proof, ask the investor password. Expert optimization in the MT4 Tester represents consecutive passes of the same expert with different inputs on the same data. At that, such parameters can be taken that make the expert efficiency maximal. Optimization is needed in two cases. You may switch off Visual mode.
Optimization is performed on the Every tick model run the tester on all the three models and compare how precise the results are. An optimized parameter is a certain factor, whose value defines the quality of a tested set of parameters. If you switch off Genetic algorithm remove the tick , the tester will pass all existing combinations of parameters through the criteria set. All inputs are listed here as a table. Inputs are variables that influence the expert operation and can be changed directly from the client terminal.
There are checkboxes to the left of variable names that include the parameter into optimization process. If a variable is not checked in this checkbox, it will not be involved into optimization. Each variable has for values. For example, you want to find out an optimal stop loss level. You understand that in day trading, it make no sense to set stop at 50 points, but, at the same time, it is not correct to set it at a level less than 10 points. You can set the minimal step, but there is no point in it.
It is not that important if the stop is 11 or 12 points, but the testing process will take more time. In my example, the expert advisor has only 5 parameters. There are robots that have much more settings. The more settings are specified, the more combinations should be checked by the tester.
At some point, the amount of combinations becomes critical and the tester stops optimization at all, that is reported as an error in the journal. This tab allows to manage limitations during optimization. If any of conditions is met during a separate pass, this pass of the expert will be interrupted.
Optimization will continue with the next pass. For example, you can specify the Balance minimum that is the level, below which it makes no sense to test the adviser, since it is not operational , after which the optimization stops. Similarly with other criteria. The best set of parameters is run on the demo account. However, this is partly the fault of the traders themselves.
Testing and optimization includes only In-Sample data. It is testing on particular basic data of a fixed period. So, traders just adjust the testing results to the needed deposit curve and the results in real trading do not match to the testing results.
These are step-by-step forward-optimization tools that repeat the passes many times with the window shifting into the future. Methods of testing and optimization are described in detail on the mql4. There are also individual variants of testing on the In-sample and Out-of-sample data: the Expert optimization on the least successful period the losing one with a subsequent run on the entire period.
Change in the market cycle. The longer is the period that you try to cover when testing, the less likely you are to get a losing system, even if you can find the optimal parameters. The market is cyclical and the expert adviser will perform different results during different cycles. Therefore, a trader has two options:. Market liquidity and market-makers.
In the testing mode, one may enter scalping trades for hundreds of lots and receive excellent results. In the real market, such a volume of transactions will inevitably shift the price, especially at relatively calm time at night.
Quality of the historical data. In short-term timeframes, there can be missing sections. What source of quotes will you recommend? We recommend you to place indicators only on those timeframes where you need them. Activate the necessary timeframes on the Timeframes tab:. You can combine more than one indicator in the oscillator window.
You can edit indicator properties, delete indicators, or delete all indicators on all charts at once. Forex Tester is a software that simulates trading in the Forex market, so you can learn how to trade profitably, create, test and refine your strategy for manual and automatic trading.
