The logic for this technical analysis indicator:

#The Aroon technical analysis indicator by Tushar Chande.

#The Aroon indicator is built by measuring the number of bars that have passed since prices 
#have reached new highs (for aroon up) or new lows (aroon down). There are three main ways 
#to interpret this indicator:

#1) Look for crossovers
#2) When either of the aroons are at extremes
#3) When aroon up and aroon down move in parallel


my ($period)=@_;
#Validate the periods
ValidatePeriods($period);
my $n=$period+1;
#Calculate the Aroon up line
my $aroonup=(HighestBar(High,$n)/$n)*100;
#Calculate the Aroon down line
my $aroondown=(LowestBar(Low,$n)/$n)*100;
#Set the name 
SetColumnName($aroonup    ,"$name($period):Up");
SetColumnName($aroondown  ,"$name($period):Down");
return ($aroonup,$aroondown);
