Where do you get that idea? Perhaps you should read the manual.

Type	Function name	Parameters	Application	Comment
int	OnInit	none	Expert Advisors and indicators	Init event handler. It allows to use the void return type.
void	OnDeinit	const int reason	Expert Advisors and indicators	Deinit event handler.

Did you build this code from the wizard? If so, you may need to add it yourself.

OnDeinit() works for both Experts and Indicators.

void OnDeinit(const int reason)
{
    Print(StringFormat("%s(): reason [%d]", __FUNCTION__, reason));
}

Exactly.

Thanks,
