The blaze loader exists to make it easy to register new pipeline datasets in zipline by reflecting information from various sources. We can automatically convert a tabular blaze expression (in a given format) to a Pipeline expression and register this with a pipeline loader (see zipline.pipeline.loaders.blaze.from_blaze; however, this loader is not registered by default so you cannot use these d

Hi,

I the documentation here it says: "Support for accessing multiple exchanges per algorithm, which opens the door to cross-exchange arbitrage opportunities."

Does catalyst really support multiple exchanges using the same algorithm? If so - how this can be done? (no documentation for it)

Thanks!

Describe the bug
I tried to implement triple_barrier_events function. IT returned an error

KeyError: 'Passing list-likes to .loc or [] with any missing labels is no longer supported, see https://pandas.pydata.org/pandas-docs/stable/user_guide/indexing.html#deprecate-loc-reindex-listlike'

Problem Description

The return documentation says "A list containing the alpha, beta, a t-stat(alpha) for the given factor and forward returns."

I am assuming "a t-stat" means "and t-sta

Tried following the quickstart guide to run the application quickly but running into many software dependency issues. Have you considered dockerizing this application?

I have a background in this area, would be interested in contributing to the project to add that capability if you are open to incorporating this as a feature.

Let me know.

According last Travis build
https://travis-ci.org/ranaroussi/qtpylib/jobs/214950579
there's currently no unit tests maybe you should add some unit tests
to ensure that coding new feature doesn't break existing code

Hudson & Thames has provided the following skillset challenge to allow potential researchers to gauge if they have the required skil

@tiingo is working on a financial statement API: https://api.tiingo.com/documentation/fundamentals

I think we should support this through the getFinancials function (which currently has no live implementations)

I'll get started on a PR, unless there are any objections

Took 58 days to hit the rook-ceph cluster issue again, and I figured I would leave this open until there's the next "days since last accident" event:
