It takes a lot for me to IGNORE you, but you can try.
Hi Kent (pips4life) and Erebus,
Great, great help. Now I am able to actually maintain a fully portable MT4 together with the data folder. Appreciate the steps & the video guys
emmzett, I supposed now whatever issues that I have using your Expander has been resolved. As long as my data folder resides together with terminal.exe, the Expander is working as expected as long as I avoid using the 'roaming' data folder by using the portable option.
Cheers,
Mel (mrcassman)

...this exact script and configuration does not work in my VPS...
...It works fine if the script is in the root directory but if I put it in a subfolder ... it can't seem to find the script...
...DebugView manages to print the file not found error from LoadMQLProgram (see attached). It seems that the function tries to search for my script in the installation directory where terminal.exe is located instead of in the MT4 Data folder...
The passed name is expected to be relative to the containing MQL4 program type folder and must not include the file extension. Passing an absolute file path or a name with file extension is considered invalid. Full documentation: LoadMqlProgramA(), LoadMqlProgramW()
Inserted Code
// MQL program types #define PT_INDICATOR 1 #define PT_EXPERT 2 #define PT_SCRIPT 4 bool LoadMqlProgramW(int hChart, PT_EXPERT, string name); // relative to "MQL4/Experts" bool LoadMqlProgramW(int hChart, PT_INDICATOR, string name); // relative to "MQL4/Indicators" bool LoadMqlProgramW(int hChart, PT_SCRIPT, string name); // relative to "MQL4/Scripts"
Attached is the current version (not recommended, always download the latest version from Github). As there is no 64bit MT4 the DLL always comes as 32bit version.
ps: When downloading from Github make sure to download the actual DLL (size about 170 KB) by clicking the "Download" button. Don't download plain HTML.
It takes blood, sweat and enough tears to wash away the blood.
Hi emmzett,
I'm probably doing something wrong here - I simply transferred my script to the subfolder within the main scripts folder.
BTW I simply connect to all my programs and data from the the MT4 terminal :
Are you saying NOT to include the absolute path?
I actually tried both cases and couldn't get it to work - the result is 'false'.
Can you see my mistake?

bool result = LoadMqlProgramW(hChart, PROGRAMTYPE_SCRIPT, path + "filename");

else Print("file retrieval not successful - " + string(GetLastError())); Are you saying NOT to include the absolute path?

Sorry to hijack your thread, but
Now I have a new problem that the script is called too often.
It supposed to be called only once when previously there was an upsignal (upsignal generated when price was above upper limit; downsignal generated when price was below lower limit and price comes back below the upper channel, then it should do nothing until the opposite signal job was done
after calling the script I did set the signal to empty... why the indi still calling script so many times?
where did I do wrong? Could someone please help meo

You have an issue with the conditions in your code and the call repeats. As this is your code unfortunately I can't help you with it.

During the same run sometimes execution succeeds and sometimes not. Please install DebugView from here or here. At the first link there are some filters which may be used to see only MetaTrader related stuff in the output. Start DebugView with admin rights (right click -> "run as administrator") and post the relevant debug messages. If the MT4Expander function fails the debug output will tell you why.
The latest DLL posted here in this thread is already more than 1 year old and in between there have been many bugfixes. Please test with the latest version from here (note that the name changed). If we manage to fix your issue I will create a new ZIP file and attach it here (will not attach before as I can't edit the post after 24h).

In this case you have to debug your script. Is it really executed? What are the inputs? and so on... This very much depends on your actual script.
"...not doing the job what script supposes to do..." raises the question: What does it do instead? A question that again can only be answered by you debugging your script.
edit: In case of any unexpected behavior from MQL or DLL (your error message "file retrieval not successful - 0") you always have to check for MQL errors, too.
Always use GetLastError() to find any bugs in your code. For example in your TMA indicator you import LoadMqlProgramA() and then you call LoadMqlProgramW(). Of course this will not work and the DLL is not involved at all. Without using GetLastError() you will not get anywhere. I call GetLastError() on every single tick and on every call to OnInit(), OnStart(), OnDeinit() and so on. This is a must when writing software.

I apply similar in another indi why result like this:
...Schaff Trend v2.02 trade GBPUSD,M15: file retrieval not successful - 0
...Schaff Trend v2.02 trade GBPUSD,M15: file retrieved successfully
...Schaff Trend v2.02 trade GBPUSD,M15: file retrieval not successful - 0

...it reported...GBPUSD,M1: file retrieved successfully but not doing the job what script supposes to do. I test by attaching the script to chart manually, script does send the order to demo account successfully...

Hopefully my following remarks will help:
You cannot run trade execution scripts in Strategy Tester, neither manually nor automated (via my script caller). The script will execute the trade commands always in your online account (demo or real), never in the tester context. The only way to execute trade commands in tester is via experts.
This is a known browser issue with latest versions of Chrome and/or Edge. Of course a DLL file can never harm a computer, except if one uses Microsoft Edge in which case everything can (and will) harm your PC. I recommend switching to a standard-conform and privacy respecting browser like Brave. Over time Chrome/Edge will kill your pc. Attached is the latest MT4Expander version. I added debug messages for each successful execution of LoadMqlProgram(). The ZIP file also contains DebugView with display filters.
Either the DLL is not called at all, or your DebugView settings are incorrect. Please make sure, that you either have the MetaTrader include filter from the first download link loaded, or that you manually enter a wildcard "*" in the include filter section. See the screenshot and click on the marked blue icon:
When the DLL loads you will get a first debug message which should look like in the screen.
You can call Help from inside DebugView by hitting F1, like in any other program. Or you go to the download location and just double-click the downloaded .CHM file.
Let me make a wild guess: The Expander will call your script in tester but your trade command will be executed on your online account. As you have no error handling in your script you just don't notice that the trades fail. Why? Because it's weekend and the market is closed. If I'm right you are very lucky. During the week your "supposed test trades" could have gone into your real account - without you even noticing.
...then I run the strategy tester, load the indicator TMa etc, which should call the trade script...To be sure that the script does its job I attach it manually to chart and can see order is sent...
...the new rsfMT4Expander.dll must be hidden as zip or data file, else I can not download from github, it reports file could harm my PC, and block download...
...In the terminal log I can see file retrieval successful. But in the debugview it is empty, nothing to send to you...
...the debugview's help file I open with edge just appeared to be empty although it is 67 kB. So it does not help...
