Forex Simulator - Troubleshooting

1. I bought the program, but I don't know how to activate it.

Please refer to installation section.

2. I do not have the activation code.

Your activation code is sent to you by e-mail automatically after making payment. If you do not have it, please check your spam folder, use our activation code recovery tool or contact us.

3. I am tired of entering my e-mail and activation code every time I start the simulator.

On versions 1.9 and above you can enable Save credentials and the simulator will remember your e-mail and code on this platform.

Save credentials

On versions prior to 1.9 you can use Save and Load buttons to store your credentials to a file and avoid entering them every time.

Load/Save buttons

4. How can I check the number of remaining activations?

The number of used activations can be checked with our activation code recovery tool. You can also contact us.

5. My MT4 accounts have expired and I have already used all my activations. What can I do?

If you ever exceed your activations limit, you can always clear your activations or contact us. It does NOT mean that you can use the software on a bigger number of accounts at the same time, but you can migrate to new accounts when your old accounts expire.

6. I can't download the program. My computer says that it can't open the file.

You do not actually need to open it. All you need to do is to save the file to your disk. Then, please follow installation instructions. Do not be scared that the file has EX4 extension, which is not recognized by your operating system and cannot be opened or executed. It is perfectly fine. It is a Metatrader add-on, not a Windows executable file (EXE).

If there are any problems with downloading the file, you can try with a different browser (e.g. Chrome, Firefox, Edge, IE, Safari, Opera) or ask us to send you the file by e-mail.

7. I get error: Could not start the simulator.

You can find more information about the problem on Experts tab of the Terminal (Ctrl + T or View -> Terminal). Please send us a screenshot or a photo of this tab and we will try to help. Taking screenshots is explained on this website.

This problem is often caused by antivirus or other security software that actively blocks Forex Simulator. You can check it quickly by disabling or turning off your antivirus for a short while. When you already know that your antivirus or security software causes the problem, you can try to reconfigure it (e.g. add an exception) to avoid turning it off completely.

Could not start the simulator


It means that you have entered either your e-mail or code incorrectly.


One license allows you to activate the program on a certain number of Metatrader accounts. The number of computers does not matter here. This message means that you have already started the simulator on all accounts and it is not possible to start it on the next account.

In order to solve this problem, try to clear old activations.

Also, you can check the number of used and remaining activations here.

10. Program activation fails due to 'INTERNET CONNECTION PROBLEM'.

Forex Simulator needs to check if your license is still valid every time you start it. In order to do that it connects to Soft4FX server. If the connections fails, you can try to solve the problem in a few ways:

Proxy server settings

11. 'Method not found: ...' error appears when I try to download data in the Data Center.

Check if Microsoft .NET Framework 4.5 or later is installed in your system: Check and install.

Method not found error

12. I am having problems with downloading historical data in Data Center.

Downloading problems may be caused by many different things. If you see any errors or other messages on the screen, please send us a screenshot or a photo. It will help to find the cause of the problem. We will also list most common problems and possible solutions below:

13. I started the simulation, but there are no bars on the chart. There is an empty chart with simulator's logo.

It is normal. The chart with logo will not be used for trading. It is required by the simulator to work, but you should not attach any indicators there. Please just leave it or minimize it.

You can create and open charts for trading in the Charts Selection window, as shown below. More information can be found in one of our video tutorials (the one titled 'charts').

Creating charts

14. My custom indicators are not working correctly with Forex Simulator.

Unfortunately, not all custom indicators will work with Forex Simulator. For example, multi-currency indicators will certainly not work. In the same way indicators that look into other timeframes may not work correctly (more information in the next question). Some custom indicators may also slow down the simulation.

All standard built-in MT4 indicators will work fine. As for custom indicators, it depends on how they were programmed. You can always test your favourite indicators using free demo version of the simulator before buying it.

Some indicators require certain number of bars on the chart to work correctly. For example, an indicator may need to see at least 100 or 200 bars. In case of lower timeframes (e.g. M1, M5, M15) this number of bars is usually available by default. However, you may need to adjust simulation settings to obtain this number of bars on higher timeframes (e.g. H4, D1, Weekly). The picture below shows which settings you should change.

New simulation settings

15. I have problems with multi-timeframe indicators.

Sometimes indicators are programmed to look at other timeframes. If you want to use such indicators on Forex Simulator, you need to create and open charts of all required timeframes, not only the one you intend to use for trading.

If you do not know which timeframes are required by your indicators, you may be forced to use trial and error method or to open all standard timeframes: M1, M5, M15, M30, H1, H4, Daily, Weekly and Monthly. You can keep them minimized, but they have to be there.

All timeframes

16. The simulator seems to work slowly on my laptop, especially when downloading data.

If you are working on a laptop, plug it in. Laptops working on battery may sometimes offer lower performance to save energy.

It is also advisable to use cable Internet connection instead of WiFi when downloading historical data. WiFi can be much slower.

Check if the simulation is working slowly because of custom indicators attached to your charts. You can check it by removing all indicators and then adding them one by one. If you see that the problem is caused by custom indicators, you can try to reduce the number of bars in chart. Shorter charts often require less computations. The number of candles in chart can be changed in Metatrader menu: Tools -> Options -> Charts -> Max. bars in chart. Sample settings can be 5000, 3000 or even 1000. Changing this setting requires exiting the simulator and restarting Metatrader.


17. Metatrader crashes when I try to close it.

It is much safer to exit Forex Simulator before attempting to close Metatrader.

18. Sometimes the simulator's window disappear when I click on it. Then, it comes back when I click on the chart. What can I do?

We know that this problem occurs to a number of customers from time to time, most likely on Windows 7. To overcome it please enable Always On Top in EA properties when launching the simulator. It is not enabled by default, because keeping the simulator on top of all other windows may not be comfortable when working with other applications.

Always On Top

19. Is there any way to make my chart template load automatically on every chart I open?

Yes. Since Forex Simulator uses offline charts, all you need to do is to save your template as offline.tpl.

20. How can I hide historical (closed) trades from my charts? There are lots of them and they make my charts too messy.

You can show and hide them with a single click in Trades window. Click Trades button in the main window, go to History tab and unselect Show historical trades on chart.

Hide trading history

21. I took a few trades, but my profit/loss is always zero and my equity and balance stay unchanged. Why is that?

Have you changed the lot size when starting the simulation? When you reduce the size of one lot, it is possible that your trades will become very very small. In such case their profit/loss will be smaller than 0.01 and it will be rounded down to zero. The standard lot size for Forex pairs is 100,000 units. Lot size for other instruments may be different. We recommend to keep the default setting unless you know exactly how this setting works.

Changing lot size

22. Everything runs very slowly after the latest update of Metatrader (build 1210).

This problem has been fixed in the next updates of Metatrader (builds 1212 and above). You have two options:

You can check your current version (build number) in Metatrader's main menu: Help -> About

Check build number
