The docs for Handling Data include sample code like:

For example ibmBar = slice.Bars["IBM"]

When I try this I get the error message:

 Runtime Error: TypeError : unindexable object at OnData in main.py:line 96
 TypeError : unindexable object

My ondata code looks like this:

def OnData(self, slice): #self.Debug('Begin OnData ' +' '+str(self.Time)+' '+str(slice.Bars.Count)+' '+str(self.curPositions)) if slice.Bars.Count == 0: return #if self.changes == None: return for tradeBar in slice.Bars.Values: sym = tradeBar.Symbol.Value self.Log('tradeBar Sym: '+ sym) crmBar = slice.Bars["CRM"] self.Log ('slice.count: '+str(slice.Bars.Count)+' crm: '+str(crmBar.Symbol.Value))

The universe is loaded by a custom list and the code properly logs the four symbols in the slice, including CRM, before failing at crmBar=slice.Bars['CRM'].

This is obviously test code, but related to my goal to evaluate the symbols in slice in the order they are loaded in the custom universe.  I want to evaluate potential trades in that order because the symbols loaded first have a better profit potential than the other symbols - if the trade is triggered.  

Thanks for some help, I've spent way too much time on this simple issue.
