I am trying to add p/b ratio to my pipeline but I get an error.
pb_ratio = fundamentals.valuation_ratios.pb_ratio
pipe = Pipeline(
screen = high_dollar_volume,
columns = {
'pb' : pb_ratio
}
)
The error that I get is...
AttributeError: Neither 'UserInstrumentedAttribute' object nor 'Comparator' object associated with UserInstrumentedAttribute has an attribute 'ndim'
Add
.latest to the fundamental value you want to fetch, that way it should work.
pb_ratio = fundamentals.valuation_ratios.pb_ratio.latest
@Luca
pb_ratio = fundamentals.valuation_ratios.pb_ratio.latest
I get the following error...
AttributeError: 'UserInstrumentedAttribute' object has no attribute 'latest'
How do you import
fundamentals?
This works for me:
from quantopian.pipeline.data import morningstar
morningstar.valuation_ratios.pb_ratio.latest
Just replace
fundamentals.valuation_ratios.pb_ratio.latest
with
morningstar.valuation_ratios.pb_ratio.latest
