Isn't the "Home" key on the keyboard better suited for this purpose? Or do you mean browsing on a mobile device where you can't use the keyboard?

I know about "Home", but it is so inconveniently located on the keyboard that I have to release the mouse to press it and pull the left hand very far away )

I also have a mouse in my hand, so the "up" button is a must-have, as long as the main manipulator is a mouse.

Compilation error: tree optimization error

class A {
public:
        void f() {}
        static void g() { A::f(); }
};

void OnStart()
{
        A::g();
}

There should be another error, which the compiler generates by specifying

        static void g() { f(); }

How do I download the signal history programmatically? I wrote it in C#:

web.Credentials = new NetworkCredential(user, pass, "mql5.com"); //"www.mql5.com" also tried

web.DownloadFile("https://www.mql5.com/ru/signals/25221/export/history", path);

But instead of csv history file, it downloads authorization page.

An example on MQL5 will also work.

There are errors in the time display (TF) in the strategy tester during optimisation.

After completion of optimization, running single test, the TF parameters become seemingly normal

But when trying to run a single test again with other parameters it fails (another pass from the optimization table). More precisely, all parameters change without problems, except TF - it stays the same.

What is the problem?

This has never been a problem before.

In the forum, the Profile font and forum language selection has become small and unreadable:

Now I'm also seeing some kind of mishap with the styles in the header and top right corner, and it manifests itself differently on PC and tablet. On the PC the line with the language names is shifted after Spanish and before Portuguese for some reason, and due to that extra shift the bottom part of the header with search and balance overlaps the horizontal menu at the top. The search line on the tablet covers the name of the site, i.e. I see "Automated Trading and Testing" and then the input field ;-).

[A100]

template<typename T>
void delta( T t1, T t2 ) {}

bool g() { return ( true ); }
void f1( int a ) { delta( a, -g()); } //нет ошибки
void f2( int a ) { delta( a, +g()); } //ошибка компиляции

Technically, there is an error - a type mismatch. In one case the compiler generates an error, but not in the other case

And what is the difference?

Please specify the browser you're using.

You are welcome to contact Service Desk and we will solve the problem.

What's the difference?

Let's see.

The difference is that the unary minus turns the argument into an int.

You can check with the following code.

template<typename T>

void  name(T t) { Print(typename(T)); }

bool g() { return(true); }

void OnStart()

  {

   name(-g());

  }
