Hi,
I am running this code below, with simple strategy, which should result in lots of buy/sell, but i don't see any happening and end portfolio values stays same.
from __future__ import (absolute_import, division, print_function,

dt = dt or self.datas[0].datetime.date(0)
print('%s, %s' % (dt.isoformat(), txt))

Is something wrong with my strategy?
