ds.get_data (tickers='CSR#(INBPBAAPF,M)|E , MGLCS00(PS)|E',fields= ['P'], start='2011-01-01', end='2019-08-10', freq='M',kind=1)

This expression is not working. When run without the second term it produces data

ds.get_data (tickers='CSR#(INBPBAAPF,M)|E',fields= ['P'], start='2011-01-01', end='2019-08-10', freq='M',kind=1)

Gives me the data but when combining two tickers it does not.
