Thank you. Does this not only work in indicators, but also in robots?

I don't know your problem, but it flips the array

We need indexes in the array to coincide with the shift value relative to the current bar, like inindicator buffers.

You need the index values to match the candlesticks after the appearance of new candlesticks, like in indicators.

Try it, it should work

It doesn't work like this. I write 300 in index 0, when a new candlestick appears it should be 300 in index 1, but no.

#property strict

int bars;
double arr[];

int OnInit()//////////////***OnInit()****///*************OnInit()*******/////////***/////////////////////OnInit()
{
   Comment("");
   
   bars = Bars(NULL, 0);
   bool series = ArraySetAsSeries(arr, true);
   int size = ArraySize(arr);
   int res = ArrayResize(arr, bars);
   arr[0] = 300;

   return(INIT_SUCCEEDED);
}//+------------------------------------------------------------------+
void OnDeinit(const int reason)//////////////**////////*OnDeinit()****////////////////////*************OnDeinit()
{       
        Comment("");  
}//+------------------------------------------------------------------+
void OnTick()//////////////***OnTick()****///*************OnTick()**********/////////////////////////////OnTick()
{
   if(bars!=Bars(NULL, 0))
   {
        bars=Bars(NULL, 0);
        int res = ArrayResize(arr, bars);
   }
   
   Comment(TimeCurrent(), "  ", bars, "  ", arr[0], "  ", arr[1], "  ", arr[2], "  " , arr[3]);
}//+------------------------------------------------------------------+

I can write myself "displacement" of the whole array in the loop at new candlesticks, but the language for working with charts, probably, there is something standard.

It needs to be filled in another way

Yes, there is a standard one... Add to the array and remove from the array. The array should be dynamic. Look in the documentation for more details, I don't remember how they are written...

Turns it over, but there is no point

does not work

(May someone remember?))

Something about arrays

 
Vitaly Muzichenko #:

Something on arrays
