There is an error in the profile.

In your profile, on the home page there are links: signals, products, jobs. Each link leads to a different section.
If you open the newsfeed, there are these links too, but the signals link refers to products.

Thank you for your message,

We will correct it.

I open the Depth of Market and I see in the log

RR      2       12:29:32.931    Books   invalid book transaction [GBPUSD,buy,1.51150,0]
CF      2       12:29:33.259    Books   invalid book transaction [GBPUSD,sell,1.51188,0]

Is it supposed to be like this ?

Also how is this consistent with market and cancel

i don't get information about broker's behavior in the log file

JS      0       12:30:00.187    Trades  '*******': market sell 2.00 GBPUSD
FJ      0       12:30:00.203    Trades  '*******': market sell 2.00 GBPUSD placed for execution in 22 ms

Compilation error

class A {
};
соnst A* f( const A *a ) { Print( "1" ); return ( a ); }
      A* f(       A *a ) { Print( "2" ); return ( a ); }
void OnStart()
{
        const A *a1 = new A();
        const A *a2 = f( a1 );

              A *a3 = new A();
              A *a4 = f( a3 ); //Ошибка компиляции
}

I tried the C++ compiler - it understands that (where MQL has an error) it is f() with Print("2" ) that needs to be called, while MQL has an uncertainty.

A simpler version also compiles with an error

void f( const A *a ) { Print( "1" ); }
void f(       A *a ) { Print( "2" ); }
void OnStart()
{
        const A *a1 = new A();
        f( a1 );

        A *a3 = new A(); //ошибка компиляции
        f( a3 );
}

What do the pluses have to do with it? They are two different languages! With pluses, the MQL is only visually similar.

How to add a level to the indicator.

Discussion, suggestions and thanks are acceptedhere

Adding level 50 to the RSI indicator

The RSI indicator now has level 50

Is there any way to do this programmatically?

[Vladimir Gospodinov]

For example

#property  indicator_level1     25.0
#property  indicator_level2     75.0

or

IndicatorSetDouble(INDICATOR_LEVELVALUE, 0, 25.0);
IndicatorSetDouble(INDICATOR_LEVELVALUE, 1, 75.0);

Hello. I have the following problem: After a forced reboot (e.g. after installing an update), all charts are closed. How can I activate the Open Deleted function? Previously this could be done in the Tools-Charts tab, now I don't see such an option

This broker says the dollar has depreciated.... for a few moments!? Down 100,000p. I wonder who was standing to sell.... Will the profits be paid out?

How did you study MQL? - From scratch from the reference book?
