Drawing Two Horizontal Lines at a given time.

I have started this code to draw 2 horizontal line across the chart for the highest and lowest candle for 20 candles this works fine but I want to only find the highest and lowest candle between the times of 10am to 11am. At the start of a new day these lines need to reset ready for the new 10am - 11am lines.

I will add the buy signal and functions later.

void OnTick()  
  {
//  MqlDateTime TimeInformation[];
//  ArraySetAsSeries(TimeInformation,true);
//  double TimeData = CopyBuffer(Symbol(),Period(),0,20,TimeInformation);
  
   MqlRates PriceInformation[];  //create an array for the price data
   ArraySetAsSeries(PriceInformation,true);  //sort the array current candle downwards  
   int Data = CopyRates(Symbol(),Period(),0,40,PriceInformation); //fill the array with price data
   
   
   int HighestCandle;      //create variable for highest price
   double High[];           //create array for price data
   ArraySetAsSeries(High,true);     //sort array from current candle downwards
   CopyHigh(Symbol(),Period(),0,20,High);    //fill the array with the high prices
   HighestCandle = ArrayMaximum(High,0,20);  //get the highest candle price


if (TimeLocal() == ElevenAM)
         ObjectCreate(0,"High",OBJ_HLINE,0,0,PriceInformation[HighestCandle].high); //set object properties
         ObjectSetInteger(0,"High",OBJPROP_WIDTH,2);              //set object width
         ObjectSetInteger(0,"High",OBJPROP_COLOR,clrIndigo);      //set object colour
      
       //  ObjectMove (0,"High",0,0,PriceInformation[HighestCandle].high);    //move the line
 
 
   int LowestCandle;      //create variable for highest price
   double Low[];           //create array for price data
   ArraySetAsSeries(Low,true);     //sort array from current candle downwards
   CopyLow(Symbol(),Period(),0,20,Low);    //fill the array with the high prices
   LowestCandle = ArrayMinimum(Low,0,20);  //get the lowest candle price


 
         ObjectCreate(0,"Low",OBJ_HLINE,0,0,PriceInformation[LowestCandle].low); //set object properties
         ObjectSetInteger(0,"Low",OBJPROP_WIDTH,2);              //set object width
         ObjectSetInteger(0,"Low",OBJPROP_COLOR,clrIndigo);      //set object colour
      
         ObjectMove (0,"Low",0,0,PriceInformation[LowestCandle].low);    //move the line
 
   
Comment ("Highest candle: ",HighestCandle, "Highest Price ",PriceInformation[HighestCandle].high,"\n",
         "Lowest candle: ",LowestCandle, "Lowest Price ",PriceInformation[LowestCandle].low);
