Ok, I see why we got different results. Your function did not give the correct result on my side, and it is because the array that I tested with had the last price in index 0 and not the other way around. Not sure how to speed up the lookup of the last/max index when the data is stored the other way around.

What method are you using to add values to the array on each bar? The default seems to add to the end of the array, not the beginning.

The function that got me started on this, was actually ill written, to some extent, and I could have managed without the array (in that case I put values into it in the wrong order).
So when I was testing the XAverage_a I just made a copy of the price numeric series copying the data into the array for test purposes; and hence getting the 0..N order with 0 being the last. I can see that the normal use of arrays would be to append values at the end of the array at each bar and that would require your function to calc EMA over it.

Hi,

I've been looking at how to pass the values of an array out of a function in Multicharts so that it can be used in an indicator. I have read this in the Multicharts Programming Guide;

Usage Example (function named "MaxValArray"):
Input: MyNumericArray[M](NumericArray);
Variable: Result(0);
Result = MyNumericArray[0]; //Reset variable each time.
For Value1 = 1 To M begin
if MyNumericArray[Value1] > Result Then Result = MyNumericArray[Value1];
end;
MaxValArray = Result;

However it seems that we are just passing the value of M to this function. Will the Array MyNumericArray now have values that can be used by the indicator when it calls MaxValArray? I can't seem to get this working and getting

------ Compiled with error(s): ------
Invalid array dimension value.
line -1, column -1

Does anyone have an example of a function that can be called by an indicator where the value of an array can be passed in/out of this function?

Many Thanks

you should use
"Input: MyNumericArray[10](NumericArray);"
instead of
Input: MyNumericArray[M](NumericArray);

use real number not a variable
