Installation

Used packages and environment

Main package: Zipline
Python 3.8 or above (currently support up to 3.11)
Microsoft Windows OS or macOS or Linux
Other Python dependency packages: Pandas, Numpy, Logbook, Exchange-calendars, etc.

How to install Zipline Reloaded modified by TEJ

We're going to illustrate under anaconda environment, so we suggest using Anaconda as development environment.
Download dependency packages.

Windows (zipline-tej.yml)
Mac (zipline-tej_mac.yml)

Start an Anaconda (base) prompt, create an virtual environment and install the appropriate versions of packages: (We strongly recommand using virtual environment to keep every project independent.) (reason)

Windows Users
# change directionary to the folder exists zipline-tej.yml
$ cd <C:\Users\username\Downloads>

# create virtual env
$ conda env create -f zipline-tej.yml

# activate virtual env
$ conda activate zipline-tej
Mac Users
# change directionary to the folder exists zipline-tej_mac.yml
$ cd <C:\Users\username\Downloads>

# create virtual env
$ conda env create -f zipline-tej_mac.yml

# activate virtual env
$ conda activate zipline-tej

Also, if you are familiar with Python enough, you can create a virtual environment without zipline-tej.yml and here's the sample :

# create virtual env
$ conda create -n <env_name> python=3.10

# activate virtual env
$ conda activate <env_name>

# download dependency packages
$ pip install zipline-tej

While encountering environment problems, we provided a consistent and stable environment on Docker hub.

For users that using docker, we briefly introduce how to download and use it.

First of all, please download and install docker-desktop.


1. Start docker-desktop. (Registration is not must.)

2. Select the "images" on the leftside and search "tej87681088/tquant" and click "Pull".

3. After the image was downloaded, click the "run" icon the enter the optional settings.

3-1. Contaner-name: whatever you want.

3-2. Ports: the port to connect, "8888" is recommended.

3-3. Volumes: the place to store files. (You can create volume first on the left side.)

e.g. created a volume named "data", host path enter "data", container path "/app" is recommended.

4. Select the "Containers" leftside, the click the one which its image name is tej87681088/tquant

5. In its "Logs" would show an url like 
http://127.0.0.1:8888/tree?token=XXXXXXXXXXXXXXXXXXXXXXXXXXXXXX

6. Go to your browser and enter "http://127.0.0.1:<port_you_set_in_step_3-2>/tree?token=XXXXXXXXXXXXXXXXXXXXXXXXXXXXXX"

6-1. If your port is 8888, you can just click the hyperlink.

7. Start develop your strategy!

NOTICE: Next time, we just need to reproduce step4 to step6.

Quick start

CLI Interface

The following code implements a simple buy-and-hold trading algorithm.

from zipline.api import order, record, symbol

def initialize(context):
    context.asset = symbol("2330")
    
def handle_data(context, data):
    order(context.asset, 10)
    record(TSMC=data.current(context.asset, "price"))
    
def analyze(context=None, results=None):
    import matplotlib.pyplot as plt

    # Plot the portfolio and asset data.
    ax1 = plt.subplot(211)
    results.portfolio_value.plot(ax=ax1)
    ax1.set_ylabel("Portfolio value (TWD)")
    ax2 = plt.subplot(212, sharex=ax1)
    results.TSMC.plot(ax=ax2)
    ax2.set_ylabel("TSMC price (TWD)")

    # Show the plot.
    plt.gcf().set_size_inches(18, 8)
    plt.show()

You can then run this algorithm using the Zipline CLI. But first, you need to download some market data with historical prices and trading volumes:

Before ingesting data, you have to set some environment variables as follow:

# setting TEJAPI_KEY to get permissions loading data
$ set TEJAPI_KEY=<your_key>
$ set TEJAPI_BASE=https://api.tej.com.tw

# setting download ticker
$ set ticker=2330 2317

# setting backtest period
$ set mdate=20200101 20220101

Ingest and run backtesting algorithm

$ zipline ingest -b tquant
$ zipline run -f buy_and_hold.py  --start 20200101 --end 20220101 -o bah.pickle --no-benchmark --no-treasury

Then, the resulting performance DataFrame is saved as bah.pickle, which you can load and analyze from Python.

More useful zipline commands

Before calling zipline in CLI, be sure that TEJAPI_KEY and TEJAPI_BASE were set. Use zipline --help to get more information.

For example : We want to know how to use zipline run, we can run as follow:

zipline run --help


Usage: zipline run [OPTIONS]
  Run a backtest for the given algorithm.

Difference of tquant and fundamentals

Basically, tquant is the one that only contain OHLCV and cash dividend date. And fundamentals is the data that exclude from OHLCV, like EPS, gross margin, operating income, etc.
So in both fundamentals and tquant, we can add tickers as follow :

Add tickers

$ zipline add -t "<ticker_wants_to_add>"

If tickers are more than 1 ticker, split them apart by " " or "," or ";".

[fundamentals only] Add fields

$ zipline add -f "<field_wants_to_add>"

NOTICE that you CAN'T add field and ticker simultaneously.

For more detail use zipline add --help .

Display bundle-info

$ zipline bundle-info

To show what the tickers are there in newest bundle.

For more detail use zipline bundle-info --help .

Switch bundle

Before using switch, use zipline bundles to get the timestamp of each folder.

$ zipline switch -t "<The_timestamp_of_the_folder_want_to_use>"

Due to zipline only using the newest folder, switch can make previous folder become newest.

For more detail use zipline switch --help .

Update bundle

You can either update tquant or fundamentals by using -b to select which one you want to update the bundle information to newest date.[DEFAULT:tquant]

$ zipline update -b tquant
$ zipline update -b fundamentals

For more detail use zipline update --help .

Jupyter Notebook

Change Anaconda kernel

Since we've downloaded package "nb_conda_kernels", we should be able to change kernel in jupyter notebook.

How to new a notebook using specific kernel

(1) Open anaconda prompt

(2) Enter the command as follow :

# First one can be ignore if already in environment of zipline-tej
$ conda activate zipline-tej 
# start a jupyter notebook
$ jupyter notebook

(3) Start a notebook and select Python[conda env:zipline-tej]

(4)(Optional) If you have already written a notebook, you can open it and change kernel by clicking the "Kernel" in menu and "Change kernel" to select the specfic kernel.

Set environment variables TEJAPI_KEY, ticker and mdate

* ticker would be your target ticker symbol, and it should be a string. If there're more than one ticker needed, use " ", "," or ";" to split them apart.

* mdate refers the begin date and end date, use " ", "," or ";" to split them apart.

In[1]:
import os    
os.environ['TEJAPI_KEY'] = <your_key>    
os.environ['ticker'] ='2330 2317'
