Quantopian Introduction - AI In Finance?

Today, let's have some fun of AI in finance. We are going to use a tool named Quantopian. As far as I know, functional programming language Haskell has been widely used in quantitative analysis. That's possibly why a dependent package of Quantopian, namely pandoc, requires The Haskell Tool Stack for its installation. Therefore, Haskell and pandoc need to be installed before Quantopian installation.

1. Preparations

1.1 Haskell Installation

Please refer to https://docs.haskellstack.org/en/stable/install_and_upgrade/:

➜  ~ curl -sSL https://get.haskellstack.org/ | sh

1.2 pandoc Installation

Please refer to https://pandoc.org/installing.html:

4
➜  ~ git clone https://github.com/jgm/pandoc
➜ ~ cd pandoc
➜ ~ stack setup
➜ ~ stack install

1.3 Zipline Installation with pip (ERRORS)

1.6 Python Package Compatibility

Let's take a look at the compatibility of python packages.

➜  ~ pip list --outdated
Package Version Latest Type
---------- --------- ------ -----
bcolz 0.12.1 1.2.1 sdist
networkx 1.11 2.2 sdist
pandas 0.22.0 0.23.4 wheel

Clearly, Zipline is NOT compatible with the above 3 LATEST python packages.

2. Register Quandl and Ingest Data

As known, Quantopian is a Python collections of various quantitative analysis algorithms. However, where can we obtain the stock data for our testing? Either the real-time data, or the historical data will do.

We can of course use the real-time Yahoo Finance Data. But here, we are going to test on some historical data downloaded from Quandl, which is JUST the data adopted in Quantopian's Beginner's Tutorial.

After you've successfully registered Quandl and obtained an API key, the following command will help you to ingest Quandl WIKI Bundle data easily, please refer to http://www.zipline.io/bundles.html#ingesting-data:

3. First Try

Details can be easily found at http://www.zipline.io/beginner-tutorial.html. Here, we ONLY test the example ./zipline/examples/buyapple.py, which can also be found on Github.

Following the Beginner's Tutorial, by executing the following command,

1
➜  examples git:(master) ✗ zipline run -f ./buyapple.py --start 2016-1-1 --end 2018-1-1 -o buyapple_out.pickle

we should be able to obtain the resultant figure as follows:
