how to have the text removed after removing the indicator

Jens89 2017.05.27 12:30

Hi,

I have some indicators which display text on the screen using the ObjectCreate function

after I remove the indicator, the text is still visible.

What I thought was needed was ObjectDelete in the deinit function but that doesn't seem to do the trick.

in another indicator I have I don't even have the Objectdelete and I have no problem with the text being removed.

thanks

If your indicator has created a graphic object, then your indicator should be removed afterward - your indicator should remove the graphic object.

Example:

The indicator Size of candles (text) creates OBJ_TEXT objects and deletes them in OnDeinit.

thanks for your quick reply

so should:

int OnDeinit()

{

ObjectDelete("whatever the name of the indicator is called");

}

always delete whatever you created?

just curious why it has to be OnDeinit and not deinit?

quite new to MQL4 so not sure yet.

thanks
