Re: [amibroker] Code Help Please

["David Jennings" <davidjennings@xxxxxxxxxxxxx>]

Tony,

Thanks for the idea. I seem to get even more bizarre results using ==.

The results using _trace and text output are consistent. 

By way of example I now get:

XPermK =   88.497

XPermD =   89.110

XpermShort =   0.000

XpermLong =   1.000

Test1L =    0.000

Test2L =    0.000

Test3L =    0.000

Test1S =    0.000

Test2S =    0.000

Test3S =    0.000

Value4 =  100.000

TempL =    0.000

Inter2 =    0.613

Upperbound is 85 and lowerbound is 15.

Hence, would expect to find templ is true and test1L is true etc...

  Try using == instead of = in your IIF statements. 

  For example, 

  IIF(templ = True 

  should be coded as 

  IIF(templ == True

    I have a piece of code which seems straight forward but I seem to be struggling. i have written it in a number of different ways e.g. using if statements in a loop and using iif statements as below. However, I seem to have a problem which ever way I write it insofar that Test1L & Test1S  fail to evaluate correctly. Herewith a snippet:

           t1 = XPermK - XpermD;

           inter2 = abs(XPermK - XpermD);



           TempL = IIf (XpermD[j] >UpperBound AND XPermK[j] >UpperBound, True,False);

           Test1L = IIf(tempL = True  AND abs(t1) < 2, True, False);

           Test2L=       IIf(XpermD < Lowerbound AND XPermK < Lowerbound AND t1 > 2.0,True, False);

           Test3L=IIf(XPermK >Lowerbound AND XPermK > XPermD,True,False); 

           

           Test1S = IIf(XpermD < Lowerbound AND XPermK < Lowerbound AND abs(t1) < 2,True,False); 

           Test2S = IIf(XpermD > UpperBound AND XPermK[k] > UpperBound AND t1> 2,True,False); 

           Test3S = IIf(XPermK < UpperBound AND XPermK < XPermD,True,False); 



           XPermLong = IIf(Test1L = True OR Test2L[j] = True OR Test3L[j] = True,True, False);

           

           XpermShort =IIf(Test1S = True OR Test2S = True OR Test3S = True,True,False);



    For instance Test1l can return false and Test1L will evaluate as true.

    Most grateful if someone could help me understand why I have it around my neck.
