Thank you William ,
What is missing here is how do I declare the array A[5].
Arrays in Amibroker are temporal .. (i.e. there is an entry per
trading day). In this case we have an Array that does not depend on a
particular day, It is just to create less error prone and more elegant
software.
I hope this explains it.
Thanks again,
Sam
