Floating Point Exception Error

[lonew0lf 10]

I've got a few tradestation indicators that i've been trying to get working in MC. The indicators compile without issue, however when I try and load them into a chart I get:

 

Message: Error in study "PSS_S_PR": :{EXCEPTION} Floating Point Exception Error.

 

Any ideas?

 

 

Input:

LeftStrength(10),

RightStrength(2),

CheckPivotValue(true);

 

Vars:

nColor(0),

nDir(0),

nShift(0),

nPrc(0),

nBar(0),

iIdx(0),

txtID(Symbol + "_PRS"),

ret1(0), ret2(0);

Array:

float arrVal1[100](0);

 

DefineDLLFunc: "PSS_PR.DLL", int , "PSS_ZZ_AddBar",INT,LPSTR,LONG,LONG,INT,int,LPLONG,LPLONG,LPLONG,LPLONG,INT;

DefineDLLFunc: "PSS_PR.DLL", int , "PSS_ZZ_CalcPiv", INT,LPSTR,LONG,INT,INT,LPFLOAT;

 

nBar = BarNumber;

if CheckPivotValue = false then

nBar = -BarNumber;

ret1 = PSS_ZZ_AddBar(CustomerID,txtID,Date,Time,nBar,PriceScale,&Open,&High,&Low,&Close,Volume);

ret2 = PSS_ZZ_CalcPiv(CustomerID,txtID,BarNumber,LeftStrength,RightStrength,&arrVal1[0]);

 

if ret2 <> 0 then begin

//====== DRAW NEW PIVOT =====================================

nShift = arrVal1[0];

nDir = ret2;

nPrc = arrVal1[1];

if nDir > 0 AND nShift < MaxBarsBack then // avoid chart/DLL reload when AutoDetect reloads because of shift

Plot3[nShift](nPrc,"PivotHigh");

if nDir < 0 AND nShift < MaxBarsBack then

Plot4[nShift](nPrc,"PivotLow");

 

//====== CHECK IF WE CONSOLIDATED OLD PIVOTS AWAY ===========

if AbsValue(nDir) > 1 then begin

nShift = arrVal1[4];

nDir = ret2;

nPrc = arrVal1[5];

if nDir > 0 AND nPrc > 0 AND nShift < MaxBarsBack then

Plot1[nShift](nPrc,"PivotHighOld");

if nDir < 0 AND nPrc > 0 AND nShift < MaxBarsBack then

Plot2[nShift](nPrc,"PivotLowOld");

end;

end;

Hi there,

 

Just a hunch, but at first I would think the exception is coming from the dll and not from the code unless you are possibly not passing in a float as the required float param. That would be my first place to look, but I'm no EL expert....

 

With kind regards,

MK

Also, possible typo's in your dll function calls??? I see the odd space where there should be none.

Thanks, I'll take a look once more and see if that does it.
