Good evening .

 if(count==0)comment+="No symbols for trading!";
      Comment(comment);
      MqlTick tick;
      tick.ask=SymbolInfoDouble(structPairs.name,SYMBOL_ASK);
      tick.bid=SymbolInfoDouble(structPairs.name,SYMBOL_BID);

What does this piece of code say? When does it appear? All pairs in the list are there and all history is loaded .

Investor password?

If some counter is 0 (I'm guessing it's the result of a previous run), then a line is added to the comment

No symbols for trading!

the rest is business as usual...

Thank you

Checking that there is no object on the second bar

         for(int jj=i;jj<obj_total;jj++)
           {
            nameARs=ObjectName(jj);
            if(ObjectType(nameARs)!=OBJ_RECTANGLE) continue;
            if(StringFind(nameARs,"QUADRO",0)!=-1)
              {

               time_ars=ObjectGetInteger(0,nameARs,OBJPROP_TIME);//break;

              }
           }
         //===---===
         if(time_ars!=Time[i+2])
           {
           //....
           }

How do I check that there are no objects on the ten bars?

[Roman Sharanov]

Indicator.

For each bar, calculate the sum of bullish bar sizes and the sum of bearish bar sizes

In the buffer write the difference of these sums.

What is wrong here?

int counted_bars=IndicatorCounted(),
       limit;
 
   if(counted_bars>0)
      counted_bars--;
   
   limit=Bars-counted_bars;
   
   double up_sum=0, down_sum=0;
   for(int i=0;i<limit;i++)
   {
      for(int f = 0; f < Period; f++){
         if(close[f] - open[f] > 0) up_sum += close[f] - open[f];
         if(close[f] - open[f] < 0) down_sum += MathAbs(close[f] - open[f]);
      }
      PVTBuffer[i]=up_sum-down_sum;
   }

Transfer

double up_sum=0, down_sum=0;

inside the first cycle - before announcing the second cycle.

Try to reset the variablesup_sum=0, down_sum=0;

before the second, internal loop.

int counted_bars=IndicatorCounted(),
       limit;
 
   if(counted_bars>0)
      counted_bars--;
   
   limit=Bars-counted_bars;
   
   double up_sum, down_sum;
   for(int i=0;i<limit;i++)
   {
    up_sum=0; 
    down_sum=0;
      for(int f = 0; f < Period; f++){
         if(close[f] - open[f] > 0) up_sum += close[f] - open[f];
         if(close[f] - open[f] < 0) down_sum += MathAbs(close[f] - open[f]);
      }
      PVTBuffer[i]=up_sum-down_sum;
   }

Like this

did so, and yes, it makes sense, but now it's no longer displayed at all

If you know how to create the exact name of an object, then there is no point in going through all the objects on the chart.
It is enough to go through these (assumed) names.

for(int i=0;i<10;i++)
   {
   if (ObjectFind(0,"QUADRO"+Time[i])<0)
      Print("Нет объекта на баре № ",IntegerToString(i));
   else
      Print("Найден oбъект на баре № ",IntegerToString(i));
   }

Yes, also like this, fix it.

In the inner loop

for(int f = 0+i; f < Period+i; f++)
