@williamea Same here

@m_nagy7 said in Error when attaching EA to chart:

cannot open file

Simply I cannot attach the EA to charts and in the experts tap I can see the "cannot open file" message.

I tried to reinstall MT4 but it didn't fix it.

I had to manually edit the EA code and remove those lines for it to work and it is the first time for me.

Please check the attached photos.

I don't know if it is something global or it is just me.

Thank you

Hi Support,

I am getting an error when trying to attach the EA to chart:

"2018.07.09 20:47:09.554 cannot open file 'C:\Users\m_na\AppData\Roaming\MetaQuotes\Terminal\50CA3DFB510CC5A8F28B48D1BF2A5702\MQL4\Experts\MA13&ADX v1.4.ex4' [2]"

And by debugging I found out that a couple of lines in the code are causing that error:

void TesterHideIndicators(bool hide)
{
HideTestIndicators(hide);
}

//-- draw indicators after test
TesterHideIndicators(!ENABLE_TEST_INDICATORS);

Am I doing something wrong or did you guys changed anything?

Hi,

Can I use the EA to run external file or batch? For example a .exe or .bat file on my desktop.

Please let me know how.

Thank you
