ArrayMinimum returns the INDEX of the element whose value is the lowest. Now we need to get the value itself from theLow array by the indexlow:
Low[low]
Nothing...
//| Получим Low для заданного номера бара |
//+------------------------------------------------------------------+
double iLow(string symbol,ENUM_TIMEFRAMES timeframe,int do)
{
int low=0; double l=0;
ArraySetAsSeries(Low,true);
int copied=CopyLow(symbol,timeframe,0,do,Low);
if(copied>0 && index<copied){ low=ArrayMinimum(Low);//ArrayMinimum(
l = Low[low];
}
return(l);
}
Nothing...
//| Получим Low для заданного номера бара |
//+------------------------------------------------------------------+
double iLow(string symbol,ENUM_TIMEFRAMES timeframe,int index)
{
int low=0; double l=0;
ArraySetAsSeries(Low,true);
int copied=CopyLow(symbol,timeframe,0,index,Low);
if(copied>0 && index<copied){ low=ArrayMinimum(Low);//ArrayMinimum(
l = Low[low];
}
return(l);
}
What isLow in your code?
Low - Array contains Low prices from 0 to do
Where do you see it? Put an array inside your function. Initialise variablel with "-1". In general, please use the Stylizer - your code is hard to read. Also you return something anyway, even if there was an error. That's not good.
Added: and why are you comparing like that:
You will never get a result that way.
//| Получим Lowest для заданного промежутка |
//+------------------------------------------------------------------+
double iLowest(string symbol,ENUM_TIMEFRAMES timeframe,int bands)
{
double Low[];
double result=-1;
ArraySetAsSeries(Low,true);
int copied=CopyLow(symbol,timeframe,0,bands,Low);
if(copied==bands)
{
result=Low[ArrayMinimum(Low)];
}
return(result);
}
Vladimir I think it's more universal
//| Получим Lowest для заданного промежутка |
//+------------------------------------------------------------------+
double iLowest(
string symbol, // символ
int timeframe, // период
int count, // число элементов
int start // индекс
)
{
double Low[];
double result=-1;
ArraySetAsSeries(Low,true);
int copied=CopyLow(symbol,timeframe,start,count,Low);
if(copied==start)
{
result=Low[ArrayMinimum(Low)];
}
return(result);
}
//| Получим Lowest для заданного промежутка |
//+------------------------------------------------------------------+
double iLowest(
string symbol, // символ
int timeframe, // период
int type, // идентификатор таймсерии
int count, // число элементов
int start // индекс
)
{
double Low[];
int copied=0.0;
double result=-1;
ArraySetAsSeries(Low,true);
if(type==PRICE_CLOSE)copied=CopyClose(symbol,timeframe,start,count,Low);
if(type==PRICE_OPEN)copied=CopyOpen(symbol,timeframe,start,count,Low);
if(type==PRICE_HIGH)copied=CopyHigh(symbol,timeframe,start,count,Low);
if(type==PRICE_LOW)copied=CopyLow(symbol,timeframe,start,count,Low);
if(copied==start)
{
result=Low[ArrayMinimum(Low)];
}
return(result);
}

Thank you!!!
I can't figure out how to add a standard trailing stop class to an EA, show me an example if you don't mind.
