Hi, when doing a History request I am getting an error: AributeError:'Series'objecthasnoaribute'volume. I was having some trouble earlier with some tickers giving other errors and was able to resolve them with suggestions in this post 

https://www.quantconnect.com/forum/discussion/8229/object-not-callable-error-midway-in-backtest/p1

but am now having some additional problems. I attached a backtest with the offending lines commented out (lines 76 and 77, with lines 78 and 79 also being commented out as example of what I was trying to do). If anyone would know the issue it would be greatly appreciated. Thanks.
