autosave graph every hour

[Umarzuki Bin Mochlis Moktar]

Is there already a solution to automate these:

1. right click
2. save picture as
3. active chart (as is)
4. save into IIS image webfolder where I can open from phone's web browser

Hi, Please specify what you mean by "save picture as". Do you need to save a screenshot of the entire screen, MT5 terminal window or just an MT5 chart?

You can use an easy solution like the one I provided below, or you can build on it.

Please note that MT4 will not let you write outside of the {MT4 Data Folder} / MQL4 / Files folder so you can do a simple trick and add a symlink to your IIS images web folder inside the  {MT4 Data Folder} / MQL4 / Files. This way the files will actually be written to the IIS images web folder.

Creating symlinks is relatively easy, but if you don't know what they are and how to create them, you can look here: https://www.maketecheasier.com/create-symbolic-links-windows10/

Instead of symlinks you can also use Windows API calls via DLL imports to copy the file over, but that may be a bit of an overkill - a symlink should be sufficient.

Anyway, here is an EA you can use for the screengrab process:

I am not sure what is wrong, i am just not getting it to work. When executed in MetaEditor the screenshot appears but not getting saved but when  i am executing CSV file data export it is getting saved.

Any help would be highly appreciated.

Thank You.
