I'm trying to use these two data sets:
Fundamentals.operation_ratios.long_term_debt_equity_ratio
Fundamentals.operation_ratios.current_ratio
I get the error:
AttributeError: type object Fundamentals has no attribute 'operation_ratios'
When I look on https://www.quantopian.com/help/fundamentals, it suggests there should be an operation_ratios
attribute.
What am I doing wrong?
