Hugh,
You can just dereference the array to pull out a specific bar value.
Just use myArray[i] where myArray is any array and i is any valid bar
index.
e.g.
for (i = 0; i < BarCount; i++) {
myScaler = myArray[i];
}
Your formula suggests: rtn = Close[i]/Open[i] - 1 though it is not
clear what bar index you would be starting with.
Also, if I interpret your requirements correctly, you may find the
following post helpful, which provides a working script to persist
ordered ranks into composites ~Position1, ~Position2, etc. such that
~Position1 holds the top ranked value at each bar, ~Position2 holds
the second top ranked value at each bar, etc.
