Please tell me. There are two buffers with values in the indicator.

Buf1[0]=12.00000;
Buf2[0]=0.00045;

Trying to get the value of the third buffer.

Buf3[0]=Buf2[0]/Buf1[0];

Nothing.

What am I doing wrong?

Thank you.

You do not receive. You are writing it down.

I don't get it.

You assign a value to the 3rd buffer. "And nothing" is what? )))

How are you trying to get this value?

I'm assigning a quotient from dividing the values of the second and first buffers.

An empty buffer is obtained.

The buffer is empty.

Maybe it's not the buffer that is empty, but the graph?)

That's how it works.

void OnStart()
{
   double   Buf1[];
   double   Buf2[];
   double   Buf3[];
   
   ArrayResize(Buf1,1);
   ArrayResize(Buf2,1);
   ArrayResize(Buf3,1);
   
   Buf1[0]=12.00000;
   Buf2[0]=0.00045;
   
   Buf3[0]=Buf2[0]/Buf1[0];
   
   ArrayPrint(Buf3);
}

Thank you, but I have a question. The buffers I have are indicative and look like.

Buf1[0]=Buf1[0]+delta1;
Buf2[0]=Buf2[0]+delta2;

Will it work in this form?

Oleg Bondarev:

Thank you, but I have a question. My buffers are indicative and have a view.

Will it work in this form?

The buffer is a regular array. I think you are writing longer questions than you could check with a simple example. Everything you wrote will work and can even be simplified.

Buf1[0]+=delta1;
Buf2[0]+=delta2;

Thank you all for your help!
