How do I load an index (Dow, Nasdaq) with Zipline?

Question

加载单个股票是没有问题的，但是我一直在加载股票索引方面苦苦挣扎，所以我认为应该分享。

Answer 1

If you want to load an index with zipline just add it to the stock parameter like this:

    data = load_from_yahoo(stocks=['AAPL', '^gspc', '^ixic'], indexes={}, start=datetime(2014, 1, 1), end=datetime(2015,4,2))

This will load both Apple's stock prices, NASDAQ Composite and s&p500.
