Comrades!

There is a need to output the indicator in segments.
It is desirable to clear the buffer, so as not to display old data on the chart.

The problem is:
1. You can't clear the array, an error will appear (out of range).
2. When zeroing the data accordingly the graph crawls to zero.

Advice on which direction to dig. Thank you.

Hello, the indicator in ex4 is very CPU intensive, if I make an indicator that pulls its buffers not on every tick but (in one, two) and put it instead of ex4 will it help the processor?

Hi. The indicator in ex4 puts a lot of load on the processor, if I make an indicator that pulls its buffers not on every tick but (in one, two) and put it instead of ex4 will it help the processor?

I would choose two approaches:
- Either work with the buffer on a new bar;
- or update the buffer on a limited time period.

I would choose the third option. I would throw out such an indicator so that no one would ever be able to find it.

Try putting EMPTY_VALUE instead of zero

[Andrei Savchenko]

I put in indicators and advisers

int init()
  {
   if(Digits==5){if(Close[0]>1)plus=0.00003; else plus=0.00002;}
   if(Digits==3){if(Close[0]>100)plus=0.003; else plus=0.002;}
}


void start()
  {
   if(time0!=Time[0]){ time0=Time[0]; hig=0; loww=1000;} 

   if((High[0]>hig)||(Low[0]<loww))  {hig=High[0]+plus; loww=Low[0]-plus;

код здесь, поскольку интересуют пиковые моменты индикаторов

хочу так
буфер_0=iCustom(NULL,0,"1rd",1,0);


}

Thank you, it helped.

how to do it:

let's say I have an account balance of 5800

if (5800)\2000= (in this case it should come out 2, all fractions are discarded, we need the functions themselves for such processing)

trader781:
just like 1800\2000=1

No. It will be 0.

Alexey Kozitsyn:
No. It will be 0.

I erased that part because I'm going to have to do it separately.
