    parameters

    Specific parameters (or specific meaning):

      - ``dataname``: The filename to parse or a file-like object

      - The lines parameters (datetime, open, high ...) take numeric values

        A value of -1 indicates absence of that field in the CSV source

      - If ``time`` is present (parameter time >=0) the source contains
        separated fields for date and time, which will be combined

      - ``nullvalue``

        Value that will be used if a value which should be there is missing
        (the CSV field is empty)

      - ``dtformat``: Format used to parse the datetime CSV field. See the
        python strptime/strftime documentation for the format.

        If a numeric value is specified, it will be interpreted as follows

          - ``1``: The value is a Unix timestamp of type ``int`` representing
            the number of seconds since Jan 1st, 1970

          - ``2``: The value is a Unix timestamp of type ``float``

        If a **callable** is passed

          - it will accept a string and return a `datetime.datetime` python
            instance

      - ``tmformat``: Format used to parse the time CSV field if "present"
        (the default for the "time" CSV field is not to be present)
