Correlation for Period as Array

[wealthwise]

Dear AFL Experts,

The Calculation of Correlation() has below logic:

function Correlation( x, y, period )
{
nom= MA( x * y, period ) - MA( x, period ) * MA( y, period );
denom = sqrt( MA( x ^ 2, period ) - MA( x, period ) ^ 2 ) *
sqrt( MA( y ^ 2, period ) - MA( y, period ) ^ 2 );
return nom/denom;
}

Note: X and Y are array1 and array2. period is not an array but a static number.

The issue I am facing is, I need to pass the parameter "Period" Dynamically and not Static Period. I have an array called "period".

But above function only accepts a period as a static value and not array.

Any one can help me with hacking this? It's lot more challanging for my AFL skills yet.

I'm not sure what you are talking about but MA function does allow variable period.
See www.amibroker.com/guide/a_varperiods.html

PS: Please use code tags for inserting code!

I got my Answer. Thank you very much fxshrat for replying.

BTW the function of post #1 is from www.amibroker.com/guide/afl/correlation.html
It would be nice to add a link to the source next time in case a code is not yours.

Why do ask same question in other forums at the same time?
For example groups.yahoo.com/neo/groups/amibroker/conversations/messages/194785

So now you effectively make other people in other forums or here waste their time?

Asking a qts in one forum is no guarantee that members in that forum will be able to or be even interested in that qts to answer. Asking in two forums increases the probabilities of getting an answer (pretty much what we do in investing world, always adding to the odds or probabilities). Also, it's no waste of anyone's time, If one is interested in the qts, hence will reply else they will just move on.

Please make a note, I did clearly mention that I got an Answer as a comment. That means the poster is now aware not to answer it anymore.

Members of one forum don't know that you are asking the same question at the same time in another forum.
And it is quite often to be seen that people using similar tactics don't actually re-post in any forum (they posted their question) when they got the solution! They just disappear then.
You would not define that as a highly selfish attitude, would you. I even call that moronic.
Also it is quite impertinent to look for a solution but just posting "I got an answer". What answer?

Seriously, I just can't stop shaking my head.
