Past Performances (How can I open/view *.HST files?)

same as in indicator file like iClose(......) functions

Anyone know where I can find a simple tutorial for using "History Center"?

See 'How works downloading from History Center'

It helps a bit, but it's in chinese.

What I would like to do is, be able to import data.

Then able to use that data with EA code.

Does anyone know a simple example of how to do that?

Aha...

I've found a way...

https://docs.mql4.com/files/FileOpen

...

Sample Code:

  int handle;
  string str;
  handle=FileOpen("my_data.csv",FILE_CSV|FILE_READ,';');
  if(handle<1)
    {
     Print("File my_data.dat not found, the last error is ", GetLastError());
     return(false);
    }
  else{
     str=FileReadString(handle);
     Print(str);
     FileClose(handle);
  }

However, I have another question.

How can I open/view *.HST files?

Write your own viewer. HST-format is known.

BTW standard instruments-timeframes can be viewed via main menu - Tools - History Center

LOL. I'm such a newbie, I don't even know what that means.

For now, I'm just going to stick with simple *.csv & *.txt files.

As seen in my sampled code above, I know how to successfully work with *.csv/*.txt files using just EA code.

And, I can simply (and successfully) view the *.csv/*.txt file's content with MS Windows Notepad.
