Generic PandasDirectData (and others) ?

  • K

    Hi,
    I see that you have enabled the possibility to add custom data lines using GenericCSVData (see the blog post) - however, I think it would be beneficial to enable custom data lines for other feeds as well (e.g., PandasDirectData etc.).

    I tried to naivly adopt the code of GenericCSVData for PandasDirectDate, i.e.:

    class GenericPandas(bt.feeds.PandasDirectData):


    lines = ('feature',)
    params = (('feature', 3),)

    and then

    data = GenericPandas(dataname=df,...)

    But this does not seem to work. The question is whether I am doing something wrong or if it is currently just not possible.

    Any help is very much appreciated. Thank you.

    That's not right. Defining line hierarchies is the basis of platform. Each indicator defines its own set of lines.

    The linked blog post doesn't even mention the topic. It simply describes how to use the GenericCSVData feed.

    Pandas based data feeds can also be extended. See here Community - Pandas DataFeed Example

    Thanks for the clarification. I had a few misleading conceptual ideas about backtrader but the reference cleared things up.
