Hello I have definied some conditions about fundamental factors in order to select stock that meet these conditions. Within the FineSelectionFunction, I create the following list:
filtered_fine = [x for x in fine if ((x.EarningReports.BasicEPS.OneMonth - x.EarningReports.BasicEPS.ThreeMonths)/ (x.EarningReports.BasicEPS.ThreeMonths)) > 0.25
and (x.OperationRatios.ROE.OneMonth) > 0.17
and ((x.FinancialStatements.IncomeStatement.TotalRevenue.OneMonth -x.FinancialStatements.IncomeStatement.TotalRevenue.ThreeMonths)/ (x.FinancialStatements.IncomeStatement.TotalRevenue.ThreeMonths)) >0.25]
When the algo start to run I have the following error:
Runtime Error: InvalidOperation : [<class 'decimal.DivisionUndefined'>]
at FineSelectionFunction in main.py:line 51
at <listcomp> in main.py:line 51
InvalidOperation : [<class 'decimal.DivisionUndefined'>] (Open Stacktrace)
I write with try and except to handle the error but the error continue. Sth know how to fix this?
Thanks for the help

Hi Nicolas, not every fundamental factor has values for multiple periods. When you use the fundamental factor value, please add a check to make sure their values are not zero.
filtered_fine = [x for x in fine if x.EarningReports.BasicEPS.OneMonth != 0 and x.EarningReports.BasicEPS.ThreeMonths != 0 and ((x.EarningReports.BasicEPS.OneMonth - x.EarningReports.BasicEPS.ThreeMonths)/ (x.EarningReports.BasicEPS.ThreeMonths)) > 0.25You can check if the value of a fundamental factor for the specified period is available via the research notebook.
# add a few symbols and retrieve the factor value without specifying the period qb.GetFundamental(["AAPL","AIG","BAC","GOOG","IBM"], "EarningReports.BasicEPS")For example the output "3M:0.035714; 6M:0.075714; 9M:0.055714; 12M:0.083571" means EarningReports.BasicEPS data are available for ThreeMonths, SixMonths, NineMonths and TwelveMonths.
