Zipline problems with data.history

Hi,

I'm trying to use the new data.history() method in Zipline, but it doesn't seem to work.

In fact, when I try to run one of the examples I get the following error:

  File "./dual_moving_average.py", line 43, in handle_data  
    short_mavg = data.history(context.sym, 'price', 100, '1d').mean()  
AttributeError: 'BarData' object has no attribute 'history'

I've checked that I am running version 0.9.0 of zipline (with python -c "import zipline; print(zipline.__version__)" )

Can anyone help me solve this error?

Thanks!
Iñaki

I think there's a google group for zipline.

Did you ever figure out your issue?

I'm seeing the same error. I'm running in a notebook on quantopian though.

PS found your post on the google group: https://groups.google.com/forum/#!topic/zipline/xFvhLdEIIf8 but since I'm on quantopian, I don't think I can update my version
