Both tradindexed and buffindexed needs space for index
between low and high mark even if the data does not exists.
E.g, there are only two overview data for the group and
the number is 100,000 and 500,000.  You need (500,000-100,000)
*sizeof(index) = 12.8MB(tradindexed), 14.4MB(buffindexed).

The data I wrote is got from a server which runs only 2 days.
