ibflex.parser.FlexParserError: SymbolSummary.tradeDate - Can't convert 'MULTI' to <class 'datetime.date'>

Hey @csingley.

Found this issue recently while testing the package from master branch.

>>> res = parser.parse(response)
Traceback (most recent call last):

For now, I'll just remove this attribute from the query configuration.

Best regards.
