Can't export the EA
-
Hello sir,
i got your application by searching google. it is looking best and easy. but when i downloaded it for trial then one problem happened. i created an ea on the trial application and exported it to ea for trial. but i couldn't get the ea. it only exports a error EX4 file. if i can't get the ea then how can i test it and how can i believe that it is working as per my idea ? please answer me. waiting for your reply. -
What is the error? First you have to setup your MetaTrader directories, so that the output files are directly written there. If the project has errors, then error message in red area is displayed.

As a newbie, I created a simple, Basic, EA as per sample on YouTube. [If ADX > 25 and SMA of 20 > SMA of 40, Buy. If SMA of 20 <= SMA of 40, Sell, etc.]. However, when I click on the export to ex4 (in an MT4 folder in its expert folder), nothing happens. What am I missing? Can any of you who have been able to compile an EA help? Thanks.

This is old video, and it shows what happens in the web version. In the local version there is no export, because the file is written directly into the "/experts" folder. Even the web version now can do that (with a little plugin for Firefox or Chrome).

Thanks for your quick response! However, although I've been able to see the program instructions in the resulting .eml file, how do I access those instructions to attach them to an MT4 site, or from within an MT4 system, i.e., how do I get from this .eml file to a .mq4 file (and thence compile it from within the MT4 system to a .ex4 file, which I DO know how to do)? Thanks.

You mean .xml file? XML is a standard format that contains some data, it's mostly used to transfer data in internet, but I decided to use it to store project data to it - blocks position, parameters and so on. But this file is used to export the project in order to import it to another account, for example. You can give me .xml file from your project and I can import that project into my fxDreema account, and MetaTrader is not involved to this at all.
fxDreema writes projects data at the end of .mq4 file as well, so I will eventually drop that .xml file functionality.
If you wonder how to get the .ex4 file:
In local version, in fxDreema go to Options->Global Options and set correct MetaTrader folders. Then when you click on .ex4 it will write .ex4 file to "experts" subfolder. There will be no prompt every time.
In web version, normally there is a prompt. But as I said above, there is a plugin for Firefox and Chrome which allows the browser to write to local folders directly, so the same goes here - set correct MetaTrader directories in the global options. -
Yes, I meant .xml file (sorry about my typo, or brain freeze!). Can't address it more today, but thanks, and will check it out.

Now I'm totally mystified! I downloaded the fxdreema connector plugin into Mozilla (I normally use Internet Explorer). How do I find the fxdreema connector plugin in Mozilla and then use it? I went back to the fxdreema application and saved the project, and then clicked on .ex4, but could not find it in the experts file of my "FXDD Malta - MetaTrader 4" folder. I don't think anything happened. How do I get the .xml file to convert to the .ex4 file? What procedure should I follow to get the connector plugin to do what it's supposed to do? Is it really so complicated? I'd like to try out the software but cannot even get the basic procedure started once a simple program is placed on the fxdreema drawing table. I use Windows 7. I would appreciate some guidance. Thanks!

No one says that .xml should be converted to something or used at all. I told that I will remove that exporting format actually, because the project is already exported with .mq4 file.
There is a big extra visible button in fxDreema that says with big clear letter ".ex4", so obviously this is the one who generates .ex4 files. There is another one ".mq4" for source code... but you don't need that.
I will say this again - you definately don't need .xml file, so don't think about how to convert it. But if you are so interested - fxDreema is the tool to convert this .xml file to .ex4 file... kind of. This .xml file contains fxDreema project data... but if you already see blocks and connections, then this .xml file is already "imported".
If the export of .ex4 file is successfull, it will say that it is successfull, otherwise it will show error message. And if you export .ex4 file name for the first time, MetaTrader needs to be restarted (in order to see that EA to the lists).

I'm okay with all of that about the .xml file, etc. But when I create the EA on the drawing board, and click on either the .mql4 button or the .ex4 button, it does not put any .mql4 or .ex4 file anywhere in the destination file set up in the Global Options dropdown window (even after closing the MT4 program and reopening it). Where could it be, or how do I find it (I'm trying to use the Local Version)? In fact, what would the file's name be? Should I try the Internet version instead, or would it produce the same non-result? Sorry to be such a pest, but this is quite frustrating!

What you should define in Global Options is the folder where MetaTrader is installed, for example:
C:\Program Files\MetaTrader 4
If you still have problems with this, I can help you with TeamViewer.

Oh!!! It worked now. I discovered that I had entered
Program Files(x86)\MetaTrader - Alpari UK, instead of
Program Files (x86)\MetaTrader - Alpari UK [ Note the space before the (x86) ]But also, when you click on the .mql4 or .ex4 buttons, it opens up a little dropdown picture which you also can click on to see the code (I hadn't realized you can do this). Also the file was called "Empty". Is there a way to name the file before clicking .ex4? It would also be helpful to have a Browse button to enter the location pathway (so idiots like me don't enter typos!).
Thanks for your help.

Normally if the output folder is not correct, it should open Global Options automatically, or at least it should show you error message (message in red background that says that something is wrong). None of this happened?
It's true that I have to put a browse button, I have to check how is that possible with html because I still don't know how. But normally I copy/paste adresses (with Ctrl+C and Ctrl+V), so maybe because of this I don't see this as big problem... even when it happens very often for someone to write wrong MetaTrader directory.
Click on that "Empty" text and you can rename the project. When you create a new project, the first thing is to give it a name... and that name is used for the output file. I also have to make it possible to write custom file name, no matter what is the project name... but I'm not really sure if this is good idea.

Sounds good. Good luck with it all, and thanks!
About the red-background error item, I don't remember seeing such a thing, but I could be wrong -- I was trying to figure out what on earth to do at the time, and may never have noticed it early on. Yes, I see the name field now when first starting a project.
