As mentioned previously, I got tired of editing the absolute indices (e.g.,
$trade[$i]->[6]) every time the order or meaning of an element of the

This is what I meant when I said a hash is a good solution to this problem.
You're not really interested in the order, you want to access each element
by a convenient name.
It sounds like a bit of data to keep in memory, so going from an array to a
hash may not be feasible because of that, but if it is it would look like
this instead:
$trade[$i]->{"time_elapsed"}
If your available memory can take this hit, I'd consider that approach a
lot more maintainable. If not, go with either exported constants or simply
$UPPER_CASE_VARIABLES as named indices into the array.
And to me it looks like the solution would be more clear with each record
being an object, but if you're not familiar with OO, don't start
introducing it in this program. Try it out with something small and new.
