[amibroker] Why writeif returns the same value all the time?

["googool123123" <bfallahi@xxxxxxxxx>]

Maybe I did not ask my question clearly -- sorry about that

I was not implying that there is something wrong with writeif (...)

I am merely asking if someone can kindly tell me what is wrong with my code


could someone please tell me why in the following code that causes 

the line

trendText = WriteIf(trendup , "Trend UP", "Trend Down");

to always return the same value regardless of the values of Coppock and CoppockMinusN

it always returns "Trend UP"

Thanks 


here's the code

TimeFrameSet( inMonthly ); // switch now to hourly


//Returns the array with months(1-12)
monthArray = Month();

closeCurrentMonth = C;
closeLatMonth = Ref(C, -1);

Coppock =
(ROC(Close,14 )*10 + ROC(Close,11)*10 +  
ROC(Ref(Close,-1),14)*9 +   ROC(Ref(Close,-1),11)*9 + 
ROC(Ref(Close,-2),14)*8 +   ROC(Ref(Close,-2),11)*8 + 
ROC(Ref(Close,-3),14)*7 +   ROC(Ref(Close,-3),11)*7 + 
ROC(Ref(Close,-4),14)*6 +   ROC(Ref(Close,-4),11)*6 + 
ROC(Ref(Close,-5),14)*5 +   ROC(Ref(Close,-5),11)*5 + 
ROC(Ref(Close,-6),14)*4 +   ROC(Ref(Close,-6),11)*4 + 
ROC(Ref(Close,-7),14)*3 +   ROC(Ref(Close,-7),11)*3 + 
ROC(Ref(Close,-8),14)*2 +   ROC(Ref(Close,-8),11)*2 + 
ROC(Ref(Close,-9),14) +   ROC(Ref(Close,-9),11))/2;

N = 1;

CoppockMinusN =
(ROC(Ref(Close, -N),14 )*10 +           ROC(Ref(Close, -N),11)*10 +  
ROC(Ref(Ref(Close, -N),-1),14)*9 +   ROC(Ref(Ref(Close, -N),-1),11)*9 + 
ROC(Ref(Ref(Close, -N),-2),14)*8 +   ROC(Ref(Ref(Close, -N),-2),11)*8 + 
ROC(Ref(Ref(Close, -N),-3),14)*7 +   ROC(Ref(Ref(Close, -N),-3),11)*7 + 
ROC(Ref(Ref(Close, -N),-4),14)*6 +   ROC(Ref(Ref(Close, -N),-4),11)*6 + 
ROC(Ref(Ref(Close, -N),-5),14)*5 +   ROC(Ref(Ref(Close, -N),-5),11)*5 + 
ROC(Ref(Ref(Close, -N),-6),14)*4 +   ROC(Ref(Ref(Close, -N),-6),11)*4 + 
ROC(Ref(Ref(Close, -N),-7),14)*3 +   ROC(Ref(Ref(Close, -N),-7),11)*3 + 
ROC(Ref(Ref(Close, -N),-8),14)*2 +   ROC(Ref(Ref(Close, -N),-8),11)*2 + 
ROC(Ref(Ref(Close, -N),-9),14) +      ROC(Ref(Ref(Close, -N),-9),11))/2;

trendUp = IIf(Coppock > CoppockMinusN, True, False);


trendText = WriteIf(trendup , "Trend UP", "Trend Down");
AddTextColumn(trendText , "Trend");
