Ninja's Volume bars not loading data

  1. Hi,
    I'm wondering if I can get some help with this oddity.

    If I choose minute data for ES and ask for n days back, I get it. :cool:

    If I choose Volume bar data(10000) for ES I don't get any previous day's history. Ninja does not attempt to load any data. :confused:

    Am I missing something?
  2. Nevermind.

    "Ninja does not backfill tick or volume charts from IB. It does backfill seconds/minutes/daily charts from IB.

    IB doesn't provide historical tick data - it only provides 1 second bars. Some software (not NT) will use these 1 second bars and massage ticks from them. Of course some accuracy is lost when you do this - you may or may not even notice the difference, however, depending on your tick or volume interval."
