extending bt.feeds.PandasData

bobaleaux

I surrender!
I am reading the data from pd.read_sql and all is well and i can run a "generic" strategy
BUT
no matter how many different ways i've tried, I can't figure out how to include the "int1", "int2", etc. columns so that i can call them like ohlc values into the strategy.

what and where do i put it?
please?

Hello,

Here is how I do that :

toinou222

class custom_data_loader(btfeeds.PandasData):
    lines = ("signal","prediction",)
    params = (("signal", -1),("prediction", -1))
    datafields = btfeeds.PandasData.datafields + (["prediction", "signal",])

Basically, I use regular PandasData.datafields and add the columns I want

Hope it helps
