Hi All,
This might be a rookie mistake but I'm trying to filter fine fundamental data based on quick ratio but in Python it seems to be unable to find it, I get the following error:
Runtime Error: TypeError : Cannot get managed object
at <listcomp>
filteredFine = [x for x at fine if x.OperationRatios.QuickRatio >= 1]
File "main.py" in main.py: line 72
(Open Stacktrace)My code looks like this:
def SelectFine(self, algorithm, fine):
filteredFine = [x for x in fine if x.OperationRatios.QuickRatio >= 1]The same QuickRatio property works in C#. Might this be a bug or am I misusing the API? Perhaps the Quick Ratio is available in a different class?

Hey Viktor,Â
fine.OperationRatios.QuickRatio is a multi period field and as such, you need to specify a period. For QuickRatio the available periods are OneYear and ThreeMonths. I'm not sure what you need but the following examples should work:Â
1.)
2.)

Thanks, that makes sense. I guess it worked in C# because there it has a default period.
