Itlooks like you have tried to download MT4 from official Metaquotes website. Unfortunately, Metaquotes does not offer MT4 downloads on their website any longer. Even when you click 'Download Metatrader 4', all you get is Metatrader 5. In this way they try to force everyone to move to MT5.
However, you can download MT4 from a Forex broker of your choice. Most Forex brokers offer MT4 downloads. You may need to register and open a demo account with selected broker in order to download it. Creating a demo account is free and usually takes only a few minutes. There are hundreds of brokers who offer MT4. We can't advertise any of them, but here is a short list: IC Markets, Alpari, Oanda, FxPro, FXCM, Forex.com, Plus500, Pepperstone, ...
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 and it is not recognized by your operating system. It is perfectly fine. It is a Metatrader add-on, not a Windows executable file (EXE).
Make sure that you know the location of the file on your disk so that you can find it. If you are not sure where your web browser stores the file, you can find it using Ctrl + J shortcut in the browser and choosing Show in Folder or Open Downloads Folder.
You have to be logged in to broker's account to start the simulator. Please check the connection status in bottom right corner of Metatrader. The status should show in green/blue. If it shows in red, it means that you are not connected.
If you have already established an account with a broker, please right-click on Accounts in Navigator window in Metatrader and choose Login to Trade Account. Fill in your account details and password and click Login. Then, check the connection status again and make sure that it turns to green/blue.
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.
Another solution is to place Forex Simulator.exe file manually in the right folder. We have shared this file on Google Drive. You can download it here. Choose the right folder according to your version, go into that folder and download only the .exe file. Do not download the whole folder. Then, copy the file to MQL4\Files folder. So, go to File -> Open Data Folder in Metatrader's main menu, navigate to MQL4 and then to Files. Put the file in that folder, possibly overwriting the existing file. Hopefully, it will solve the problem.
If you are testing the software in demo mode, the amount of available data will be limited to sample 2 years. It is normal that you won't be able to download more data. Also, it is normal that you won't have the most recent data. Sample 2 years doesn't mean last 2 years.
Make sure there are enough days between the starting day of simulation and the first day of available data. If there are not enough days, you can either download more data or start the simulation from a later date.
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 currency pairs is 100,000 units. Lot size for other instruments may be different. We recommend to keep default setting unless you know exactly how this setting works.
If you already know that the problem is related to indicators, you may try to limit the number of bars on chart. Many indicators will work faster on shorter charts. You can reduce the number of bars when creating the chart in Charts Selection window.
Unfortunately, not every custom indicator will work correctly on the simulator. Some will work fine. Some may need small adjustments in the source code. Sometimes you may be able to make them work by opening charts of other timeframes. Sometimes they just won't work, no matter what. It is because the simulator creates new symbols such as !STD_EURUSD instead of EURUSD and it uses offline charts. The environment created in the simulation is a bit different from live environment. Some MQL4 functions used in custom indicators may not work in the simulation.
Every trade requires some margin. Each time you open a buy or sell trade a portion of money (margin) is blocked for this trade. Margin requirements depend on leverage. It is actually the inverse of leverage. For example, if you set leverage to 1:100, then 1% of the size of trade will be blocked for margin. If you set leverage to 1:10, then 10% will be blocked. The bigger the leverage, the less money you need to take trades.
This error means that you are trying to take a trade which is too big and there is not enough free money in your account to cover its margin requirements. You can try to overcome this problem in the following ways:

If I run the source code in VS everything works fine. Also, the .exe in the bin folders work fine. It's only the installed version which generates the error, if I recompile and reinstall I get the same error.
I'm a bit stumped as to what's causing this and hoped for a few pointers. It seems to be a WebRequest response through IE is not being returned but I'm stumped as to why it works fine in VS without any errors. Are there any new IE security measures/polices that may cause this?
I was facing this issue and just got the reply from Paypal technical. Add this will fix the 403 issue. HttpWebRequest req = (HttpWebRequest)WebRequest.Create(url);
req.UserAgent = "[any words that is more than 5 characters]";
It may be useful to check your IIS permissions and see what accounts have access to the resource you are accessing. Cross reference that with the account you use and the account the installed versions are using.
In my case, I had to call an API repeatedly in a loop, which resulted in halt of my system returning a 403 Forbidden Error. Since my API provider does not allow multiple requests from the same client within milliseconds, I had to use a delay of 1 second at least :
In my case I had to add both 'user agent' and 'default credentials = True'. I know this is pretty old, still wanted to share. Hope this helps. Below code is in powershell, but it should help others who are using c#.
This probably won't help too many people, but this was my case: I was using the Jira Rest Api and was using my personal credentials (the ones I use to log into Jira). I had updated my Jira password but forgot to update them in my code. I got the 403 error, I tried updating my password in the code but still got the error.
The solution: I tried logging into Jira (from their login page) and I had to enter the text to prove I wasn't a bot. After that I tried again from the code and it worked. Takeaway: The server may have locked you out.
In my case I remembered that a hole in the firewall was created for this address some time ago, so I had to set useDefaultWebProxy="false" on the binding in the config file, as if the default was to use the proxy if useDefaultWebProxy is not specified.
I changed my project location and got this error. I used to remove this project from IIS (IIS contains old project reference), restart it, open my project in VS as admin and run it from VS.This resolved my issue.
Did other users encounter the same issue if they sent emails to the external email address or others in this external domain? What happens if the user send emails to another external email address(e.g. Outlook.com, Hotmail)?
Based on my research, the enhanced status code in the undeliverable message represents that there were too many hops during the email delivery between your and remote server(There could be 20 or more hops.): ** What is mail error 554 5.4.0? **. I think you could inspect and ask the sender and recipient if there are some outlook/transport rules that might cause mail to loop, try to disable them temporarily and see if there is any difference.
Forex Tester is our recommended trading simulator because it has all the features needed to make a simulator session feel as close to a live trading session as possible, while being very easy to use. You can also use code: DUOM10 to get 10% off.
The simulator allows you to rewind to previous dates and replay them on the chart as if they were live markets. This includes being able to do analysis in relative real-time, execute trades and perform all the risk management and trade management actions you would normally do. For example, you can scale in or scale out of trades, set stop losses and take profit levels.
Unlike simply doing backtesting in a normal charting platform, Forex Tester will keep track of your account balance and provide stats about your performance. This makes it a great tool for backtesting as well as practice sessions.This is a paid software, but the cost is very reasonable and a great investment for the amount of value it will bring to your trading development.
