class_docstr: A :class:`pyalgotrade.barfeed.csvfeed.BarFeed` that loads bars from CSV files exported from NinjaTrader.
  
  :param frequency: The frequency of the bars. Only **pyalgotrade.bar.Frequency.MINUTE** or **pyalgotrade.bar.Frequency.DAY**
      are supported.
  :param timezone: The default timezone to use to localize bars. Check :mod:`pyalgotrade.marketsession`.
  :type timezone: A pytz timezone.
  :param maxLen: The maximum number of values that the :class:`pyalgotrade.dataseries.bards.BarDataSeries` will hold.
      Once a bounded length is full, when new items are added, a corresponding number of items are discarded from the
      opposite end. If None then dataseries.DEFAULT_MAX_LEN is used.
  :type maxLen: int.
