Custom indicator working on Strategy Tester but not when I run it on real data from Meta Editor

Here's my code

//+------------------------------------------------------------------+
//| Custom indicator iteration function                              |

int OnCalculate(const int rates_total,
                const int prev_calculated,
                const datetime &time[],
                const double &open[],

                const double &low[],
                const double &close[],
                const long &tick_volume[],
                const long &volume[],
                const int &spread[])
  {
   // We want to draw the zone after current candle
   int target = 10;
   // bull target
   if (open[target] < close[target])
   {
      if (open[target+1] > close[target]) return -1;
      for (int i = target+1; i < target+5; i++)
      {
         if (open[i] < close[i]) return -1;         
      }
      // draw demand zone

   }
   // bear target
