Hi Group,

In Anthony Faragasso's Stochastic of Weekly array the code produces a 
week starting Friday and finishing Thursday.  Not Monday to Friday 
which I assumed it would do.

I am attempting to use this code to produce weekly Pivot Points with 
Resistance and Support on the daily chart.  All worked quite well 
except the actual days of the week were incorrect.

Does Anthony or anyone else know how I can overcome this problem.

The code is as follows;


//Support and Resistance levels

weekstart = DayOfWeek() < Ref( DayOfWeek(), -1 );
weekend = DayOfWeek() > Ref( DayOfWeek(),1);
/**Establish Weekly Price arrays**/
WeeklyOpen=ValueWhen(DayOfWeek()< Ref(DayOfWeek(),-1) ,Open);
WeeklyHigh = ValueWhen( weekend, HighestSince( weekstart, High ) );
WeeklyLow = ValueWhen( weekend, LowestSince( weekstart, Low ) );
WeeklyClose=ValueWhen(DayOfWeek() > Ref( DayOfWeek(),1),Close);
WeeklyVolume=ValueWhen(DayOfWeek() > Ref(DayOfWeek(),1),Sum(V,5)); 

P=(WeeklyHigh+WeeklyLow+WeeklyClose)/3;
R1=(P*2)-WeeklyLow;
R2=P+WeeklyHigh-WeeklyLow;
S1=(P*2)-WeeklyHigh;
S2=P-WeeklyHigh+WeeklyLow;

Plot(P,"P",colorBlack,styleLine);
Plot(R1,"R1",colorIndigo,styleDots);
Plot(R2,"R2",colorBlue,styleThick);
Plot(S1,"S1",colorIndigo,styleDots);
Plot(S2,"S2",colorRed,styleThick);
