An example of a script:

and the result:

2019.07.29 20:36:41.215 1 (EURUSD,H1)   # 1: 1.11425

Here they are.

Works on both 4pc and 5pc

In 4-rka apply Period(), Symbol(), etc.

In 5-pc, apply _Period, _Symbol(), etc.

iBars	Returns the number of bars in the history for a specified symbol and period
iBarShift	Returns the offset of the bar to which the specified time belongs
iClose	Returns the closing price of the bar of the corresponding chart
iHigh	Returns the value of the maximal price of the bar in the chart
iHighest	Returns the index of the highest found value of the corresponding chart
iLow	Returns the value of the minimum bar price of the corresponding chart
iLowest	Returns the index of the smallest found value of the corresponding chart
iOpen	Returns the value of the bar open price of the corresponding chart
iTime	Returns the bar open time of the corresponding chart
iVolume	Returns the value of the tick volume of the bar in the chart

With CopyRates, it worked. It works.

And here is theCopyRates variant

Alexey Viktorov:

Alexey, this is for those who are in a tank. And for the normal ones, CopyRates() is available in mql4 as well. So forget all iOpen and other nonsense. I don't even understand why they put it in mql5.

Oh! Teeny-weeny guys have appeared))

Why do we need in practice to have a lot of consecutive OHLC values - which you suggested to get using CopyRates() ? - except to meditate? ))))

there's not much practical use, here's a trivial task, the unloading (or use) of the Fractals indicator, i have such a code:

#define  Time(n)   iTime(NULL,0,n)
//+------------------------------------------------------------------+
void OnStart()
  {
   int handle=iFractals(NULL,0);
   if(handle==INVALID_HANDLE)
     {
      Print("Error№,",::GetLastError()," create handle indicator");
      return;
     }
   int count=0,i=0;
   double buffup[1],buffdn[1];
   while(i<Bars(_Symbol,_Period) && count<10)
     {
      if(CopyBuffer( handle,0,i,1, buffup)<1) Print("buffup , error № ",::GetLastError());
      if(CopyBuffer( handle,1,i,1, buffdn)<1) Print("buffup , error № ",::GetLastError());
      if(buffup[0]<EMPTY_VALUE && ++count>0)  Print("Bar № ",i," : ",Time(i)," , Fractals Up = ",buffup[0]);
      if(buffdn[0]<EMPTY_VALUE && ++count>0)  Print("Bar № ",i," : ",Time(i)," , Fractals Dn = ",buffdn[0]);
     i++;
     }
  }
//+------------------------------------------------------------------+

show me your code with use of CopyRates()...

Vladimir Karputov:

And here is theCopyRates variant

and result

But, if we need to constantly track data on new bars, it means to refer to CopyRates on every tick and make a timeseries on every tick?

I'm trying to figure out the best place to put CopyRates.

Реter Konow:

I'm trying to understand where better to put the CopyRates.

I've already asked above: WHY? Is it necessary to consider the value of zero bar (the rightmost bar on the chart)?

[Реter Konow]

Vladimir Karputov:

I have already asked above: WHY? Should the value of the zero bar (the rightmost bar on the chart) be taken into account?

For the table. There are four parameters in the table: Open, Close, High, Low, the last 10 bars, not including the current one.

Last, in the sense of moving backwards from the current one (zero).

Igor, you should go to the first grade. They teach letters there and after studying you will understand the difference between CopyRates and CopyBuffer.

You better offer me a solution to this problem WITHOUT CopyRates(!)

How to get Open,Low,High,Close parameters in MQL5?

Retrog Konow, 2019.07.29 19:58

For the table. There are four parameters in the table: Open, Close, High, Low, last 10 bars, not including the current one.

Last, I mean if moving backwards from the current one (zero).

In this case CopyRates from the first bar is unambiguously 10. And call it not every tick, but enough when a new bar appears.
