Maybe so:

Where is the previous day's condition here? It turns out that after the first order in the 0-8 period, the step will already be 10. And we need it to be 5. And only after 8 o'clock it will become 10. Then we return step =5 to 0 if there are no open orders from the previous day. If the series continues, then step =10 before its close.

PolarSeaman:

The point is that if you set the time interval as in the Expert Advisor

I need to exclude the candlesticks that are in the interval from the calculations.

In the indicator you work in a loop. So why do you need to exit the loop?

Don't you know how to skip an iteration in the loop?

The function should return тру, if there is an order opened yesterday

   OP_TO(int mn)
     {
     int i, k=OrdersTotal();
      for(i=0; i<k; i++) 
        {
         if(OrderSelect(i,SELECT_BY_POS,MODE_TRADES))

            if(OrderSymbol()==Symbol()) 
              {
               if(OrderType()==OP_BUY || OrderType()==OP_SELL) 
                 {
                  if(OrderMagicNumber()==mn) 
                    {
                     if(TimeDay(OrderOpenTime())==(Day()-1)
                      &&  TimeMonth(OrderOpenTime())==Month()
                      &&  TimeYear (OrderOpenTime())==Year()) return(True);
                    }
                 }
              }
           }
        }

      return(False);
     }

if(Hour()>=0&&Hour()<=8&&!OP_TO(mag_n))step = 5; else step =10;

Thank you. I don't get it, I limited the time but the print shows the time at 19:30 and 23:00 and 5:50, what's wrong?

   for(int i=limit-2; i>0; i--) 
     {
     if(Hour()>=17&&Hour()<=11)continue;
      if(i%2==0) 
        {
         if(open[i]<close[i] && open[i+1]>close[i+1]) 
           {
            k1++;
           // if(k1>max) {max=k1; dat_max=time[i];}
            if(k1>=4)Print("Num: ",k1,"dat_max ",time[i]);
            SetText("Obj_"+(string)time[i],(string)k1,time[i],high[i],Arr);
           }
         else k1=0;
         
           } else {
         if(open[i]<close[i] && open[i+1]>close[i+1]) 
           {
            k2++;
            //if(k2>max){ max=k2; dat_max=time[i];}
            if(k2>=4)Print("Num: ",k2,"dat_max ",time[i]);
            SetText("Obj_"+(string)time[i],(string)k2,time[i],high[i],Arr);
           }
         else k2=0;
         
        }
      
     }

Thank you. I don't understand, the print shows the time as 19:30 and 23:00 and 5:50 what's wrong?

What does the Hour() function return?

[Tigerfreerun]

PolarSeaman:

The function should return тру, if there is an order opened yesterday

It's a bit complicated for me. Could you explain in which part of the code to add and what does it mean mn and mag_n? where should I put my EA medjic here?

Gentlemen programmers, help me to understand the error. minPrice = NormalizeDouble (GetMinPrice(),Digits); Error: 'minPrice' - semicolon expected.

[Ihor Herasko]

Look at the code before minPrice. There is no ; (semicolon) there.

int start()

{

minPrice = NormalizeDouble (GetMinPrice()Digits);

maxPrice = NormalizeDouble(GetMaxPrice()Digits); Can int start be followed by (;) ?
