[FIX] stock: use timedelta instead of relativedelta

Browse Source 
Suppose we have a delta between two datetimes:

    delta = dt1 - dt0

If delta is negative but less than a day, ``delta.days`` returns -1 (which is
compensated by positive seconds).  In order to avoid this surprising effect,
use ``delta.total_seconds()`` to compute the number of days.
