[amibroker] Re: Exploration Question

["wlandry01" <wlandry01@xxxxxxxxx>]

Terry,

Thanks for the input.  You're absolutely right.

I was operating with a misunderstanding of how the "n last quotations"
applied to this situation.  I'm still trying to get oriented to the
array processing approach to things!

I was able to delete the "LastValue" function and simply set the "n
last quotations" to pull the latest value from the average monthly
change array.  As you noted, this greatly speeds things up.

Again, thanks for the help.


Wayne
