What I want is to save in virtual objects, the following:

The lowest price and the corresponding hour.
The highest price and the time to which it corresponds.

How could I do it?

I already have in virtual objects each price value.

In simpler tables I think I could do it with math.max or by sorting the table and keeping the first and last value. But in such a complex table and with the time, I don't know how to do it.

Try this (data is decoded JSON response):
Code:
values = data.indicator.values

table.sort(values, function(a, b)
  return a.value < b.value
end)

min = values[1]
minvalue = min.value
minhour = min.datetime:match('T(%d+)')

log(minvalue, minhour)

max = values[#values]
maxvalue = max.value
maxhour = max.datetime:match('T(%d+)')

log(maxvalue, maxhour)
