Why doent this work?!?

[Tweeker]

In my mind this should work. But i get so many errors...

Im trying to find the highest candle from current time to when i entered the deal.

double Start;

   double TimeCurrent;

   double HighestCandel;

   double High[];

   

  

   if (HistorySelect(0, TimeTradeServer()) && (HistoryDealsTotal() > 0))

    Start=(string)HistoryDealGetInteger(HistoryDealGetTicket(HistoryDealsTotal() - 1), DEAL_ENTRY);

    

   

   ArraySetAsSeries(High,true);

   CopyHigh(const string ,PERIOD_CURRENT,TimeCurrent,Start,High&[]); This is the part that isnt working.

   HighestCandel= ArrayMaximum(High,NuTid,Start);

   

   Comment ("Highest candel 1-Start: ",HighestCandel);

2. CopyHigh(const string ,PERIOD_CURRENT,TimeCurrent,Start,High&[]); This is the part that isnt working.

   It doesn't work because that line doesn't even compile.

The variables Start and TimeCurrent can't be double. They must be datetime or int. See the documentation for CopyHigh(): https://www.mql5.com/en/docs/series/copyhigh

Tweeker:

I have done this to the code. I get the highest of the last two candels but not since i started the deal.

If candle five whas biggest the comment says "MFE=1.0"

If the current candle is highest the comment says "MFE=0.0"

Please help.

Is there anyway to get the comment to say what the highest price whas and not only the highest candel?

void OnTick()
  {
  
   int Start;
   double HighestCandel;
   double High[];
   
  
   
  
   if (HistorySelect(0, TimeCurrent()) && (HistoryDealsTotal() > 0))
    Start= (string)HistoryDealGetInteger(HistoryDealGetTicket(HistoryDealsTotal() - 1), DEAL_TIME);
    
 
   
   ArraySetAsSeries(High,true);
   CopyHigh(_Symbol,PERIOD_M1,0,DEAL_TIME,High);
   HighestCandel= ArrayMaximum(High,0,Start);
   
   Comment ("MFE: ",HighestCandel);
