@Artyom Trishkin

Can you give me some business tips?

I can give you a lot of different information about turkeys.

For starters, it's a pheasant bird. It's dietary meat. I feed it to my cat. He says it's delicious...

Константин:

Can you give me a clue as to the point?

And to the point, why would you want to run the script from an indicator?

[Константин]

Mihail Matkovskij:

As for the point, who told you to be so stupid as to run scripts from an indicator? :)

And most importantly, why?

I want to make a button on the chart so that I can run a script by pressing a button with a parameter taken from the indicator

You write the code of the button in the indicator code and integrate the script code as a function in the indicator code. Press the button - call the function, in which you pass the indicator parameter.

If the problem is in creating the button itself, here it is:

Thanks, I think I've got the button figured out, but I haven't figured out how to attach the script. The script is at C:\Users\...\MQL4\Scripts\Order.ex4

[Константин]

Another question. I use a small tablet on Windows without a mouse, the buttons on the graph is a convenient solution for me. Is it possible to have the keyboard command Ctrl+F5 executed when pressing the button on the graph, it would be more convenient for me to view the following profile.

Assign a shortcut to the script and simulate it using WinAPI. But I haven't done anything like that inMQL programs. So try googling"SendInput User32.dll WinAPI".

Good afternoon!

I am struggling with one question. Could you please tell me how to solve it?

The idea is the following: I draw a line at the previous maximum of the candle. I want the line to be shifted depending on the previous maximum.

void OnTick()
  {
//---
   double   o1 = iOpen(Symbol(),Period(),1);
   double   h1 = iHigh(Symbol(),Period(),1);
   double   l1 = iLow(Symbol(),Period(),1);
   double   c1 = iClose(Symbol(),Period(),1);
   double   c0 = iClose(Symbol(),Period(),0);
   double   rt = 0;
   double   rs1 = 0;


rt=MathAbs(c1-o1)/_Point; //размер тела свечи
rs1=MathAbs(h1-c1)/_Point;// размер верхней тени свечи


if (rs1>=rt) // условие для построения уровней (если верхняя тень предыдущей свечи, больше, или равна телу этой же всечи, то...   
{
double PRH=iHigh(Symbol(),_Period,1); // то это будет максимум
ObjectCreate(0,"HL",OBJ_HLINE,0,_Period,PRH); // и строим по этому максимуму, горизонтальную линию
Comment("ЦЕНА МАКС =======",PRH,"\n"); // комментарий пред. максимума
}
}

There are 2 options

1. You have to delete the object before drawing it.

2. Set the price after creating the object
