[amibroker] Could someone point in the right direction...

["Tony" <talcamo@xxxxxxxxx>]

Hi,

I am trying to write an exploration to loop back thru 3 arrays to 
confirm how many days ago there was a crossover of the 3 moving 
averages defined below. This is related the the Bill Williams Chaos 
Theory ( the alligator). Once the exploration is executed I would be 
able to see which stocks are still in an uptrend and have been in an 
uptrend for the longest time.

However in my current formula, the for loop drops out on the very 
first pass. I cannot figure out why. It never adds anything to the 
NumberOfDays variable.

I am certain the checkAlligator formula is correct as i tested it 
manually. I just added the ref() and the index counter for my 
formula, so it could loop back through the data.

I would be gratefully if someone could explain to me what i a doing 
incorrectly? or point me in the correct direction.

Thank you kindly in advance...

Regards,

Tony


A=((H+L)/2);

AlligatorBlue=Ref(Wilders(A,13),-8);
AlligatorRed=Ref(Wilders(A,8),-5);
AlligatorGreen=Ref(Wilders(A,5),-3);
CheckAlligator = 0;
NumberOfDays =0;
for ( i=-1; stop = 0 ; i--) 			
{							

CheckAlligator =IIf( Ref(AlligatorGreen,i) > Ref(AlligatorRed,i) AND 
                   Ref(AlligatorGreen,i) > Ref(AlligatorBlue, i) AND 
                   Ref(AlligatorRed,i) > Ref(AlligatorBlue, i) ,1, 0);

// if in uptrend increment the NumberOfDays variable
if (CheckAlligator == 1 )
       NumberOfDays = 1 + NumberOfDays;
else
     stop = 1;
 
}// end for loop

Filter = C > 1;
AddColumn(i  , "index ");
AddColumn(Checkalligator  , "Checkalligator");
AddColumn(NumberOfDays  , "NumberOfDays ");
AddColumn(Close         ,  "Close");
AddColumn(AlligatorGreen,  "AlligatorGreen");
AddColumn(AlligatorRed,    "AlligatorRed");
AddColumn(AlligatorBlue,  "AlligatorBlue");
