Hello guys,

i am struggling to make this seasonality indicator from TradeStation work in MC. The code is a step beyond my average at best coding abilities.

I am getting an error message which is pointing towards the "SData(Null)" in the second line of the code. Any help would be great fully received. The indicator basically looks at the last 5 years of historical data on a weekly basis and plots the expected seasonal trend over the coming weeks and months.



Inputs: YearsToConsider(5);
vars: elsystem.collections.Vector SData(null), int Elements(0), int X(0),
OKToStart(FALSE), int CurYear(0), int CurPeriod(0), int YearCount(0),
double TempVal(0), double TempPerf(0), FirstYear(0), CumPerf(0);

method void AnalysisTechnique_Initialized( elsystem.Object sender, elsystem.InitializedEventArgs args )
begin
SData = New elsystem.collections.Vector ;
If Bartype = 3 then Elements = 52;
If Bartype = 4 then Elements = 12;

For X = 1 to Elements begin
SData.insert(0,0.0);
end;
FirstYear = year(currentdate) - (YearsToConsider);
end;

CurYear = year(date);
If CurYear >= FirstYear AND Bartype >= 3 AND LastBarOnChart = FALSE then begin

If CurYear <> CurYear[1] then begin
OKToStart = True;
CurPeriod = 0;
YearCount += 1;
CumPerf = 0;
end;

If OKToStart = True then begin
If Elements = 52 and CurPeriod > 51 then CurPeriod = 51;

TempVal = SData[CurPeriod] astype double;
TempPerf = (Close - Close[1]) / Close[1];
SData[CurPeriod] = TempVal + TempPerf;

If YearCount = YearsToConsider then begin
CumPerf = CumPerf + SData[CurPeriod] astype double / (YearCount - 1);
Plot1[-Elements](CumPerf, "Seasonal");
end;
end;

If Year(Date) <> Year(date[1]) then begin
Value1 = TL_New(Date, time, High, Date, TIme , Low);
TL_setextleft(Value1, TRUE);
TL_setextright(Value1, TRUE);
end;
CurPeriod += 1;
end;

CharlieTrader,

the code uses OOEL parts that are not available in Multicharts. You'd have to replace the vector with an array (or an Easylanguage Collection list if you prefer) and remove the method. The latter can just be replaced with a "once begin... end;" statement. The code for the vector replacement will depend on your decision to use an array or a list.

Hi,
is there any open script solution for free or to buy for MC?
Thanks

Fibonacci,

the code posted in #1 is open and free, it just needs slight modifications (as described in post #2) to make it work in MC.
If you are looking for recommendations, it might help if you describe what you want the study to do exactly.

ABCTG,

thanks for your fast reply.

First of all I want to use it with MC, I use TS as well and I know that it works,
but the modifications required are also beyond my programing skills.

Fibonacci
