what does "10 oldest deposits" mean. deposit before which date?
It means exactly that. The 10 oldest deposits.
And when one of the 10 oldest deposits, complete, then the next-oldest deposit will be added in to keep it at 10 oldest...
What he wants to do is try and knock out those deposits who have been incomplete the longest, and it will always be the 10 oldest ones at any given time.
