TheXpert:
There is no "close order" event in the terminal. You should use a script or an Expert Advisor. As shown above.

Hmm. what is the event called when you press the "cross" to close an open order?

That's what you need to "assign" a sound to

paladin800:

Thank you very much!

I also found my mistake. The point is that the "Buy_close" condition, gives the program a task to execute the deal, and the check for the position is "Buy_opened".

The deal is closed and the "Buy_close" condition coincides, therefore an error is generated.

Made the condition as follows:

if(Buy_close && Buy_opened==true)

this is the action to "assign" the sound to

Good luck :)

I can't get MA lines with an offset of -+0.30%.

There isno problem with calling the moving average from which the offset will occur. But, there is no way to get offset lines.

Basic code:

#property indicator_chart_window
#property indicator_buffers 2
#property indicator_plots   2
#property  indicator_type1   DRAW_LINE
#property  indicator_color1  clrMediumVioletRed
#property  indicator_style1  STYLE_SOLID
#property  indicator_label1  ""
#property  indicator_type2   DRAW_LINE
#property  indicator_color2  clrRed
#property  indicator_style2  STYLE_SOLID
#property  indicator_label2  "Sell TP
input int Period_ = 34;         //Период
int ma1Handle;

#property indicator_label2  "Sell TP

Where is the second inverted comma.

[Alexander Bereznyak]

CopyBuffer(ma1Handle,0,0,2,ma1Val);

This string must be in a loop and indexed.

sandex:
This string should be in a loop and indexed.

How do I index a string? Trying this, the error comes out

ArraySetAsSeries(ma1Val,true);
int bars=Bars(_Symbol,_Period);
for(int i=0;i<bars;i++)
    {
    CopyBuffer(ma1Handle,0,0,2,ma1Val[i]);
    ExtMapBuffer2[i]=ma1Val[i] - ((ma1Val[i]/100)*0.3);//ЗДЕСЬ НЕ ПОЛУЧАЕТСЯ ПОЛУЧИТЬ ЛИНИЮ
    }

[Alexander Bereznyak]

Indexing should be done like this:

CopyBuffer(ma1Handle,0,i,1,ma1Val);

[Alexander Bereznyak]

This line should look like this:

ExtMapBuffer2[i]=ma1Val[0] - ((ma1Val[0]/100)*0.3);

[Alexander Bereznyak]

Declare the array to be static, of size 1:

double ma1Val[1];
