Basically, each time I encounter N
consecutive up days, I want to perform some analysis to determine if a buy
condition was met or not. I think I understand what you have pointed out and
it looks like I will have to iterate through all bars to accomplish what I want
to do.
What I was hoping to do was do part in
_javascript_ and part in AFL. For instance if N = 3, AFL would look like this I think:
NPriceUpBars
= C > Ref( C, -1 ) &&
Ref( C, -1 ) > Ref ( C, -2 ) &&
Ref (C,
-2 ) > Ref( C, -3 ) ;
But what I wanted to do is perform the
above “AND” (&&) operation in a loop so that all I would
have to do is change my ‘N’ variable, and the code would work.
Have I explained what I am attempting to
do?

_javascript_ - exception
Hi. “C” is an array of
data. PriceUp is a Boolean. They are
incompatible.
What are you trying to accomplish?
Where is this code being executed? Why not use straight AFL?
Regards,
Dan.

Can anyone tell me why I am getting an error with the code
below:
...
priceUp = True;
c1 = C;
for ( i = 1; i <= N; i++ )
{
curBar = i * -1;
priceUp = priceUp &&
c1 > Ref( C,
curBar );
if ( !priceUp ) break;
...
}
…
I am getting an error on the line in red above. The
error is
“Condition
in IF, WHILE, FOR statements has to be Numeric or Boolean type. You can
not use array here, please use [] (array subscript operator) to access array
elements”
(BTW< the Edit->Copy Error message
function in Formula Editor is not working for me, is this a bug?)
