Backups

Pricing data is automatically compressed in redis and there is an example Kubernetes job for backing up all stored pricing data to AWS S3 <https://github.com/AlgoTraders/stock-analysis-engine/blob/master/k8/backups/backup-to-aws-job.yml>__.

Running the Full Stack Locally for Backtesting and Live Trading Analysis

While not required for backtesting, running the full stack is required for running algorithms during a live trading session. Here is a video on how to deploy the full stack locally using docker compose and the commands from the video.

.. image:: https://asciinema.org/a/220487.png :target: https://asciinema.org/a/220487?autoplay=1 :alt: Running the Full Stack Locally for Backtesting and Live Trading Analysis

#. Start Workers, Backtester, Pricing Data Collection, Jupyter, Redis and Minio

Now start the rest of the stack with the command below. This will pull the `~3.0 GB stock-analysis-engine docker image <https://hub.docker.com/r/jayjohnson/stock-analysis-engine>`__ and start the workers, backtester, dataset collection and `Jupyter image <https://hub.docker.com/r/jayjohnson/stock-analysis-jupyter>`__. It will start `Redis <https://hub.docker.com/_/redis>`__ and `Minio <https://hub.docker.com/r/minio/minio>`__ if they are not running already.

::

    ./compose/start.sh

.. tip:: Mac OS X users just a note that `there is a known docker compose issue with network_mode: "host" <https://github.com/docker/for-mac/issues/1031>`__ so you may have issues trying to connect to your services.

#. Check the Docker Containers

::

    docker ps -a

#. View for dataset collection logs

::

    logs-dataset-collection.sh

#. Wait for pricing engine logs to stop with ctrl+c

::

    logs-workers.sh

#. Verify Pricing Data is in Redis

::

    redis-cli keys "*"

#. Optional - Automating pricing data collection with the automation-dataset-collection.yml docker compose file <https://github.com/AlgoTraders/stock-analysis-engine/blob/master/compose/automation-dataset-collection.yml>__:

.. note:: Depending on how fast you want to run intraday algorithms, you can use this docker compose job or the `Kubernetes job <https://github.com/AlgoTraders/stock-analysis-engine/blob/master/k8/datasets/job.yml>`__ or the `Fetch from Only Tradier Kubernetes job <https://github.com/AlgoTraders/stock-analysis-engine/blob/master/k8/datasets/pull_tradier_per_minute.yml>`__ to collect the most recent pricing information

::

    ./compose/start.sh -c

Run a Custom Minute-by-Minute Intraday Algorithm Backtest and Plot the Trading History

With pricing data in redis, you can start running backtests a few ways:

• Comparing 3 Deep Neural Networks Trained to Predict a Stocks Closing Price in a Jupyter Notebook <https://github.com/AlgoTraders/stock-analysis-engine/blob/master/compose/docker/notebooks/Comparing-3-Deep-Neural-Networks-Trained-to-Predict-a-Stocks-Closing-Price-Using-The-Analysis-Engine.ipynb>__
• Build, run and tune within a Jupyter Notebook and plot the balance vs the stock's closing price while running <https://github.com/AlgoTraders/stock-analysis-engine/blob/master/compose/docker/notebooks/Run-a-Custom-Trading-Algorithm-Backtest-with-Minute-Timeseries-Pricing-Data.ipynb>__
• Analyze and replay algorithm trading histories stored in s3 with this Jupyter Notebook <https://github.com/AlgoTraders/stock-analysis-engine/blob/master/compose/docker/notebooks/Analyze%20Compressed%20Algorithm%20Trading%20Histories%20Stored%20in%20S3.ipynb>__
• Run with the command line backtest tool <https://github.com/AlgoTraders/stock-analysis-engine/blob/master/analysis_engine/scripts/run_backtest_and_plot_history.py>__
• Advanced - building a standalone algorithm as a class for running trading analysis <https://github.com/AlgoTraders/stock-analysis-engine/blob/master/analysis_engine/mocks/example_algo_minute.py>__

Running an Algorithm with Live Intraday Pricing Data

Here is a video showing how to run it:

.. image:: https://asciinema.org/a/220498.png :target: https://asciinema.org/a/220498?autoplay=1 :alt: Running an Algorithm with Live Intraday Pricing Data

The backtest command line tool <https://github.com/AlgoTraders/stock-analysis-engine/blob/master/analysis_engine/scripts/run_backtest_and_plot_history.py>__ uses an algorithm config dictionary <https://github.com/AlgoTraders/stock-analysis-engine/blob/master/tests/algo_configs/test_5_days_ahead.json>__ to build multiple Williams %R indicators <https://github.com/AlgoTraders/stock-analysis-engine/blob/master/analysis_engine/scripts/run_backtest_and_plot_history.py#L49>__ into an algorithm with a 10,000.00 USD starting balance. Once configured, the backtest iterates through each trading dataset and evaluates if it should buy or sell based off the pricing data. After it finishes, the tool will display a chart showing the algorithm's balance and the stock's close price per minute using matplotlib and seaborn.

::

# this can take a few minutes to evaluate
# as more data is collected
# because each day has 390 rows to process
bt -t SPY -f /tmp/history.json

.. note:: The algorithm's trading history dataset provides many additional columns to review for tuning indicators and custom buy/sell rules. To reduce the time spent waiting on an algorithm to finish processing, you can save the entire trading history to disk with the -f <save_to_file> argument.

View the Minute Algorithm's Trading History from a File

Once the trading history is saved to disk, you can open it back up and plot other columns within the dataset with:

.. image:: https://i.imgur.com/pH368gy.png

::

# by default the plot shows
# balance vs close per minute
plot-history -f /tmp/history.json

Run a Custom Algorithm and Save the Trading History with just Today's Pricing Data

Here's how to run an algorithm during a live trading session. This approach assumes another process or cron is fetch-ing the pricing data using the engine so the algorithm(s) have access to the latest pricing data:

::

bt -t SPY -f /tmp/SPY-history-$(date +"%Y-%m-%d").json -j $(date +"%Y-%m-%d")

.. note:: Using -j <DATE> will make the algorithm jump-to-this-date before starting any trading. This is helpful for debugging indicators, algorithms, datasets issues, and buy/sell rules as well.

Run a Backtest using an External Algorithm Module and Config File

Run an algorithm backtest with a standalone algorithm class contained in a single python module file that can even be outside the repository using a config file on disk:

::

ticker=SPY
config=<CUSTOM_ALGO_CONFIG_DIR>/minute_algo.json
algo_mod=<CUSTOM_ALGO_MODULE_DIR>/minute_algo.py
bt -t ${ticker} -c ${algo_config} -g ${algo_mod}

Or the config can use "algo_path": "<PATH_TO_FILE>" to set the path to an external algorithm module file.

::

bt -t ${ticker} -c ${algo_config}

.. note:: Using a standalone algorithm class must derive from the analysis_engine.algo.BaseAlgo class

Building Your Own Trading Algorithms

Beyond running backtests, the included engine supports running many algorithms and fetching data for both live trading or backtesting all at the same time. As you start to use this approach, you will be generating lots of algorithm pricing datasets, history datasets and coming soon performance datasets for AI training. Because algorithm's utilize the same dataset structure, you can share ready-to-go datasets with a team and publish them to S3 for kicking off backtests using lambda functions or just archival for disaster recovery.

.. note:: Backtests can use ready-to-go datasets out of S3, redis or a file

The next section looks at how to build an algorithm-ready datasets from cached pricing data in redis <https://github.com/AlgoTraders/stock-analysis-engine#extract-algorithm-ready-datasets>__.

Run a Local Backtest and Publish Algorithm Trading History to S3

::

ae -t SPY -p s3://algohistory/algo_training_SPY.json

Run distributed across the engine workers with -w

::

ae -w -t SPY -p s3://algohistory/algo_training_SPY.json

Run a Local Backtest using an Algorithm Config and Extract an Algorithm-Ready Dataset

Use this command to start a local backtest with the included algorithm config <https://github.com/AlgoTraders/stock-analysis-engine/blob/master/tests/algo_configs/test_5_days_ahead.json>__. This backtest will also generate a local algorithm-ready dataset saved to a file once it finishes.

#. Define common values

::

    ticker=SPY
    algo_config=tests/algo_configs/test_5_days_ahead.json
    extract_loc=file:/tmp/algoready-SPY-latest.json
    history_loc=file:/tmp/history-SPY-latest.json
    load_loc=${extract_loc}

Run Algo with Extraction and History Publishing

::

run-algo-history-to-file.sh -t ${ticker} -c ${algo_config} -e ${extract_loc} -p ${history_loc}

Profile Your Algorithm's Code Performance with vprof

.. image:: https://i.imgur.com/1cwDUBC.png

The pip includes vprof for profiling an algorithm's performance (cpu, memory, profiler and heat map - not money-related) <https://github.com/nvdv/vprof>__ which was used to generate the cpu flame graph seen above.

Profile your algorithm's code performance with the following steps:

#. Start vprof in remote mode in a first terminal

.. note:: This command will start a webapp on port ``3434``

::

    vprof -r -p 3434

#. Start Profiler in a second terminal

.. note:: This command pushes data to the webapp in the other terminal listening on port ``3434``

::

    vprof -c cm ./analysis_engine/perf/profile_algo_runner.py

Run a Local Backtest using an Algorithm Config and an Algorithm-Ready Dataset

After generating the local algorithm-ready dataset (which can take some time), use this command to run another backtest using the file on disk:

::

dev_history_loc=file:/tmp/dev-history-${ticker}-latest.json
run-algo-history-to-file.sh -t ${ticker} -c ${algo_config} -l ${load_loc} -p ${dev_history_loc}

View Buy and Sell Transactions

::

run-algo-history-to-file.sh -t ${ticker} -c ${algo_config} -l ${load_loc} -p ${dev_history_loc} | grep "TRADE"

Plot Trading History Tools

Plot Timeseries Trading History with High + Low + Open + Close

::

sa -t SPY -H ${dev_history_loc}

Run and Publish Trading Performance Report for a Custom Algorithm

This will run a backtest over the past 60 days in order and run the standalone algorithm as a class example <https://github.com/AlgoTraders/stock-analysis-engine/blob/master/analysis_engine/mocks/example_algo_minute.py>__. Once done it will publish the trading performance report to a file or minio (s3).

Write the Trading Performance Report to a Local File

::

run-algo-report-to-file.sh -t SPY -b 60 -a /opt/sa/analysis_engine/mocks/example_algo_minute.py
# run-algo-report-to-file.sh -t <TICKER> -b <NUM_DAYS_BACK> -a <CUSTOM_ALGO_MODULE>
# run on specific date ranges with:
# -s <start date YYYY-MM-DD> -n <end date YYYY-MM-DD>

Write the Trading Performance Report to Minio (s3)

::

run-algo-report-to-s3.sh -t SPY -b 60 -a /opt/sa/analysis_engine/mocks/example_algo_minute.py

Run and Publish Trading History for a Custom Algorithm

This will run a full backtest across the past 60 days in order and run the example algorithm <https://github.com/AlgoTraders/stock-analysis-engine/blob/master/analysis_engine/mocks/example_algo_minute.py>__. Once done it will publish the trading history to a file or minio (s3).

Write the Trading History to a Local File

::

run-algo-history-to-file.sh -t SPY -b 60 -a /opt/sa/analysis_engine/mocks/example_algo_minute.py

Write the Trading History to Minio (s3)

::

run-algo-history-to-s3.sh -t SPY -b 60 -a /opt/sa/analysis_engine/mocks/example_algo_minute.py

Developing on AWS

If you are comfortable with AWS S3 usage charges, then you can run just with a redis server to develop and tune algorithms. This works for teams and for archiving datasets for disaster recovery.

Environment Variables

Export these based off your AWS IAM credentials and S3 endpoint.

::

export AWS_ACCESS_KEY_ID="ACCESS"
export AWS_SECRET_ACCESS_KEY="SECRET"
export S3_ADDRESS=s3.us-east-1.amazonaws.com

Extract and Publish to AWS S3

::

./tools/backup-datasets-on-s3.sh -t TICKER -q YOUR_BUCKET -k ${S3_ADDRESS} -r localhost:6379

Publish to Custom AWS S3 Bucket and Key

::

extract_loc=s3://YOUR_BUCKET/TICKER-latest.json
./tools/backup-datasets-on-s3.sh -t TICKER -e ${extract_loc} -r localhost:6379

Backtest a Custom Algorithm with a Dataset on AWS S3

::

backtest_loc=s3://YOUR_BUCKET/TICKER-latest.json
custom_algo_module=/opt/sa/analysis_engine/mocks/example_algo_minute.py
sa -t TICKER -a ${S3_ADDRESS} -r localhost:6379 -b ${backtest_loc} -g ${custom_algo_module}

Fetching New Pricing Tradier Every Minute with Kubernetes

If you want to fetch and append new option pricing data from Tradier <https://developer.tradier.com/getting_started>__, you can use the included kubernetes job with a cron to pull new data every minute:

::

kubectl -f apply /opt/sa/k8/datasets/pull_tradier_per_minute.yml

Run a Distributed 60-day Backtest on SPY and Publish the Trading Report, Trading History and Algorithm-Ready Dataset to S3

Publish backtests and live trading algorithms to the engine's workers for running many algorithms at the same time. Once done, the algorithm will publish results to s3, redis or a local file. By default, the included example below publishes all datasets into minio (s3) where they can be downloaded for offline backtests or restored back into redis.

.. note:: Running distributed algorithmic workloads requires redis, minio, and the engine running

::

num_days_back=60
./tools/run-algo-with-publishing.sh -t SPY -b ${num_days_back} -w

Run a Local 60-day Backtest on SPY and Publish Trading Report, Trading History and Algorithm-Ready Dataset to S3

::

num_days_back=60
./tools/run-algo-with-publishing.sh -t SPY -b ${num_days_back}

Or manually with:

::

ticker=SPY
num_days_back=60
use_date=$(date +"%Y-%m-%d")
ds_id=$(uuidgen | sed -e 's/-//g')
ticker_dataset="${ticker}-${use_date}_${ds_id}.json"

start_date=$(date --date="${num_days_back} day ago" +"%Y-%m-%d")
echo ""
echo "extracting algorithm-ready dataset: ${extract_loc}"
echo "sa -t SPY -e ${extract_loc} -s ${start_date} -n ${use_date}"
sa -t SPY -e ${extract_loc} -s ${start_date} -n ${use_date}
echo ""
echo "running algo with: ${backtest_loc}"
echo "sa -t SPY -p ${history_loc} -o ${report_loc} -b ${backtest_loc} -e ${processed_loc} -s ${start_date} -n ${use_date}"
sa -t SPY -p ${history_loc} -o ${report_loc} -b ${backtest_loc} -e ${processed_loc} -s ${start_date} -n ${use_date}

Jupyter on Kubernetes

This command runs Jupyter on an AntiNex Kubernetes cluster <https://deploy-to-kubernetes.readthedocs.io/en/latest/>__

::

Kubernetes - Analyze and Tune Algorithms from a Trading History

With the Analysis Engine's Jupyter instance deployed you can tune algorithms from a trading history using this notebook <https://aejupyter.example.com/notebooks/Analyze%20Compressed%20Algorithm%20Trading%20Histories%20Stored%20in%20S3.ipynb>__.

Kubernetes Job - Export SPY Datasets and Publish to Minio

Manually run with an ssh-eng alias:

::

function ssheng() {
    pod_name=$(kubectl get po | grep ae-engine | grep Running |tail -1 | awk '{print $1}')
    echo "logging into ${pod_name}"
    kubectl exec -it ${pod_name} bash
}
ssheng
# once inside the container on kubernetes
source /opt/venv/bin/activate
sa -a minio-service:9000 -r redis-master:6379 -e s3://backups/SPY-$(date +"%Y-%m-%d") -t SPY

View Algorithm-Ready Datasets

With the AWS cli configured you can view available algorithm-ready datasets in your minio (s3) bucket with the command:

::

aws --endpoint-url http://localhost:9000 s3 ls s3://algoready

View Trading History Datasets

With the AWS cli configured you can view available trading history datasets in your minio (s3) bucket with the command:

::

aws --endpoint-url http://localhost:9000 s3 ls s3://algohistory

View Trading History Datasets

With the AWS cli configured you can view available trading performance report datasets in your minio (s3) bucket with the command:

::

aws --endpoint-url http://localhost:9000 s3 ls s3://algoreport

Advanced - Running Algorithm Backtests Offline

With extracted Algorithm-Ready datasets in minio (s3), redis or a file <https://github.com/AlgoTraders/stock-analysis-engine#extract-algorithm-ready-datasets>__ you can develop and tune your own algorithms offline without having redis, minio, the analysis engine, or jupyter running locally.

Run a Offline Custom Algorithm Backtest with an Algorithm-Ready File

::

# extract with:
sa -t SPY -e file:/tmp/SPY-latest.json
sa -t SPY -b file:/tmp/SPY-latest.json -g /opt/sa/analysis_engine/mocks/example_algo_minute.py

Run the Intraday Minute-by-Minute Algorithm and Publish the Algorithm-Ready Dataset to S3

Run the included standalone algorithm <https://github.com/AlgoTraders/stock-analysis-engine/blob/master/analysis_engine/mocks/example_algo_minute.py>__ with the latest pricing datasets use:

::

sa -t SPY -g /opt/sa/analysis_engine/mocks/example_algo_minute.py -e s3://algoready/SPY-$(date +"%Y-%m-%d").json

And to debug an algorithm's historical trading performance add the -d debug flag:

::

sa -d -t SPY -g /opt/sa/analysis_engine/mocks/example_algo_minute.py -e s3://algoready/SPY-$(date +"%Y-%m-%d").json

Extract Algorithm-Ready Datasets

With pricing data cached in redis, you can extract algorithm-ready datasets and save them to a local file for offline historical backtesting analysis. This also serves as a local backup where all cached data for a single ticker is in a single local file.

Extract an Algorithm-Ready Dataset from Redis and Save it to a File

::

sa -t SPY -e ~/SPY-latest.json

Create a Daily Backup

::

sa -t SPY -e ~/SPY-$(date +"%Y-%m-%d").json

Validate the Daily Backup by Examining the Dataset File

::

sa -t SPY -l ~/SPY-$(date +"%Y-%m-%d").json

Validate the Daily Backup by Examining the Dataset File

::

sa -t SPY -l ~/SPY-$(date +"%Y-%m-%d").json

Restore Backup to Redis

Use this command to cache missing pricing datasets so algorithms have the correct data ready-to-go before making buy and sell predictions.

.. note:: By default, this command will not overwrite existing datasets in redis. It was built as a tool for merging redis pricing datasets after a VM restarted and pricing data was missing from the past few days (gaps in pricing data is bad for algorithms).

::

sa -t SPY -L ~/SPY-$(date +"%Y-%m-%d").json

Fetch

With redis and minio running (./compose/start.sh), you can fetch, cache, archive and return all of the newest datasets for tickers:

.. code-block:: python

from analysis_engine.fetch import fetch
d = fetch(ticker='SPY')
for k in d['SPY']:
    print(f'dataset key: {k}\nvalue {d["SPY"][k]}\n')

Backfill Historical Minute Data from IEX Cloud

.. note:: IEX Cloud supports pulling from 30 days before today <https://iexcloud.io/docs/api/#historical-prices>__

::

fetch -t TICKER -F PAST_DATE -g iex_min
# example:
# fetch -t SPY -F 2019-02-07 -g iex_min

Getting Started

This section outlines how to get the Stock Analysis stack running locally with:

• Redis
• Minio (S3)
• Stock Analysis engine
• Jupyter

For background, the stack provides a data pipeline that automatically archives pricing data in minio (s3) <https://minio.io>__ and caches pricing data in redis. Once cached or archived, custom algorithms can use the pricing information to determine buy or sell conditions and track internal trading performance across historical backtests.

From a technical perspective, the engine uses Celery workers to process heavyweight, asynchronous tasks <http://www.celeryproject.org/>__ and scales horizontally with support for many transports and backends depending on where you need to run it <https://github.com/celery/celery#transports-and-backends>. The stack deploys with Kubernetes <https://github.com/AlgoTraders/stock-analysis-engine#running-on-kubernetes> or docker compose and supports publishing trading alerts to Slack <https://github.com/AlgoTraders/stock-analysis-engine/blob/master/compose/docker/notebooks/Stock-Analysis-Intro-Publishing-to-Slack.ipynb>__.

With the stack already running, please refer to the Intro Stock Analysis using Jupyter Notebook <https://github.com/AlgoTraders/stock-analysis-engine/blob/master/compose/docker/notebooks/Stock-Analysis-Intro.ipynb>__ for more getting started examples.

Setting up Your Tradier Account with Docker Compose

Please set your Tradier account token in the docker environment files before starting the stack:

::

grep -r SETYOURTRADIERTOKENHERE compose/*
compose/envs/backtester.env:TD_TOKEN=SETYOURTRADIERTOKENHERE
compose/envs/workers.env:TD_TOKEN=SETYOURTRADIERTOKENHER

Please export the variable for developing locally:

::

export TD_TOKEN=<TRADIER_ACCOUNT_TOKEN>

.. note:: Please restart the stack with ./compose/stop.sh then ./compose/start.sh after setting the Tradier token environment variable

#. Start Redis and Minio

.. note:: The Redis and Minio container are set up to save data to ``/data`` so files can survive a restart/reboot. On Mac OS X, please make sure to add ``/data`` (and ``/data/sa/notebooks`` for Jupyter notebooks) on the Docker Preferences -> File Sharing tab and let the docker daemon restart before trying to start the containers. If not, you will likely see errors like:

   ::

        ERROR: for minio  Cannot start service minio:
        b'Mounts denied: \r\nThe path /data/minio/data\r\nis not shared from OS X

    Here is the command to manully creaate the shared volume directories:

    ::

        sudo mkdir -p -m 777 /data/redis/data /data/minio/data /data/sa/notebooks/dev /data/registry/auth /data/registry/data

::

    ./compose/start.sh

Get and Publish Pricing data

Please refer to the lastest API docs in the repo:

https://github.com/AlgoTraders/stock-analysis-engine/blob/master/analysis_engine/api_requests.py

Fetch New Stock Datasets

Run the ticker analysis using the ./analysis_engine/scripts/fetch_new_stock_datasets.py <https://github.com/AlgoTraders/stock-analysis-engine/blob/master/analysis_engine/scripts/fetch_new_stock_datasets.py>__:

Collect all datasets for a Ticker or Symbol

Collect all datasets for the ticker SPY:

::

fetch -t SPY

.. note:: This requires the following services are listening on:

- redis ``localhost:6379``
- minio ``localhost:9000``

View the Engine Worker Logs

::

docker logs ae-workers

Running Inside Docker Containers

If you are using an engine that is running inside a docker container, then localhost is probably not the correct network hostname for finding redis and minio.

Please set these values as needed to publish and archive the dataset artifacts if you are using the integration <https://github.com/AlgoTraders/stock-analysis-engine/blob/master/compose/integration.yml>__ or notebook integration <https://github.com/AlgoTraders/stock-analysis-engine/blob/master/compose/notebook-integration.yml>__ docker compose files for deploying the analysis engine stack:

::

fetch -t SPY -a 0.0.0.0:9000 -r 0.0.0.0:6379

.. warning:: It is not recommended sharing the same Redis server with multiple engine workers from inside docker containers and outside docker. This is because the REDIS_ADDRESS and S3_ADDRESS can only be one string value at the moment. So if a job is picked up by the wrong engine (which cannot connect to the correct Redis and Minio), then it can lead to data not being cached or archived correctly and show up as connectivity failures.

Detailed Usage Example

The fetch_new_stock_datasets.py script <https://github.com/AlgoTraders/stock-analysis-engine/blob/master/analysis_engine/scripts/fetch_new_stock_datasets.py>__ supports many parameters. Here is how to set it up if you have custom redis and minio deployments like on kubernetes as minio-service:9000 <https://github.com/AlgoTraders/stock-analysis-engine/blob/7323ad4007b44eaa511d448c8eb500cec9fe3848/k8/engine/deployment.yml#L80-L81>__ and redis-master:6379 <https://github.com/AlgoTraders/stock-analysis-engine/blob/7323ad4007b44eaa511d448c8eb500cec9fe3848/k8/engine/deployment.yml#L88-L89>__:

• S3 authentication (-k and -s)
• S3 endpoint (-a)
• Redis endoint (-r)
• Custom S3 Key and Redis Key Name (-n)

::

fetch -t SPY -g all -u pricing -k trexaccesskey -s trex123321 -a localhost:9000 -r localhost:6379 -m 0 -n SPY_demo -P 1 -N 1 -O 1 -U 1 -R 1

Run FinViz Screener-driven Analysis

This is a work in progress, but the screener-driven workflow is:

#. Convert FinViz screeners into a list of tickers and a pandas.DataFrames from each ticker's html row #. Build unique list of tickers #. Pull datasets for each ticker #. Run sale-side processing - coming soon #. Run buy-side processing - coming soon #. Issue alerts to slack - coming soon

Here is how to run an analysis on all unique tickers found in two FinViz screener urls:

Jupyter

You can run the Jupyter notebooks by starting the notebook-integration.yml stack <https://github.com/AlgoTraders/stock-analysis-engine/blob/master/compose/notebook-integration.yml>__ with the command:

.. warning:: On Mac OS X, Jupyter does not work with the Analysis Engine at the moment. PR's are welcomed, but we have not figured out how to share the notebooks and access redis and minio with the known docker compose issue with network_host on Mac OS X <https://github.com/docker/for-mac/issues/1031>__

For Linux users, the Jupyter container hosts the Stock Analysis Intro notebook <https://github.com/AlgoTraders/stock-analysis-engine/blob/master/compose/docker/notebooks/Stock-Analysis-Intro.ipynb>__ at the url (default login password is admin):

http://localhost:8888/notebooks/Stock-Analysis-Intro.ipynb

Jupyter Presentations with RISE

The docker container comes with RISE installed <https://github.com/damianavila/RISE>__ for running notebook presentations from a browser. Here's the button on the notebook for starting the web presentation:

.. image:: https://i.imgur.com/IDMW2Oc.png

Distributed Automation with Docker

.. note:: Automation requires the integration stack running (redis + minio + engine) and docker-compose.

Dataset Collection

Start automated dataset collection with docker compose:

::

./compose/start.sh -c

Datasets in Redis

After running the dataset collection container, the datasets should be auto-cached in Minio (http://localhost:9000/minio/pricing/) and Redis:

::

kubectl apply -f ./k8/datasets/job.yml

Kubernetes Deployments - Jupyter

Deploy Jupyter to a Kubernetes cluster with:

::

./k8/jupyter/run.sh

Kubernetes with a Private Docker Registry

You can deploy a private docker registry that can be used to pull images from outside a kubernetes cluster with the following steps:

#. Deploy Docker Registry

::

    ./compose/start.sh -r

#. Configure Kubernetes hosts and other docker daemons for insecure registries

::

    cat /etc/docker/daemon.json
    {
        "insecure-registries": [
            "<public ip address/fqdn for host running the registry container>:5000"
        ]
    }

#. Restart all Docker daemons

::

    sudo systemctl restart docker

#. Login to Docker Registry from all Kubernetes hosts and other daemons that need access to the registry

.. note:: Change the default registry password by either changing the ``./compose/start.sh`` file that uses ``trex`` and ``123321`` as the credentials or you can edit the volume mounted file ``/data/registry/auth/htpasswd``. Here is how to find the registry's default login set up:

    ::

        grep docker compose/start.sh  | grep htpass

::

    docker login <public ip address/fqdn for host running the registry container>:5000

#. Setup Kubernetes Secrets for All Credentials

Set each of the fields according to your own buckets, docker registry and Tradier account token:

::

    cat /opt/sa/k8/secrets/secrets.yml | grep SETYOUR
    aws_access_key_id: SETYOURENCODEDAWSACCESSKEYID
    aws_secret_access_key: SETYOURENCODEDAWSSECRETACCESSKEY
    .dockerconfigjson: SETYOURDOCKERCREDS
    td_token: SETYOURTDTOKEN

#. Deploy Kubernetes Secrets

::

    kubectl apply -f /opt/sa/k8/secrets/secrets.yml

#. Confirm Kubernetes Secrets are Deployed

::

    kubectl get secrets ae.docker.creds
    NAME              TYPE                             DATA   AGE
    ae.docker.creds   kubernetes.io/dockerconfigjson   1      4d1h

::

    kubectl get secrets | grep "ae\."
    ae.docker.creds         kubernetes.io/dockerconfigjson        1      4d1h
    ae.k8.aws.s3            Opaque                                3      4d1h
    ae.k8.minio.s3          Opaque                                3      4d1h
    ae.k8.tradier           Opaque                                4      4d1h

#. Configure Kubernetes Deployments for using an External Private Docker Registry

Add these lines to a Kubernetes deployment yaml file based off your set up:

::

.. tip:: After spending a sad amount of time debugging, please make sure to delete pods before applying new ones that are pulling docker images from an external registry. After running the kubectl delete pod <name>, you can apply/create the pod to get the latest image running.

Testing

To show debug, trace logging please export SHARED_LOG_CFG to a debug logger json file. To turn on debugging for this library, you can export this variable to the repo's included file with the command:

::

export SHARED_LOG_CFG=/opt/sa/analysis_engine/log/debug-logging.json

.. note:: There is a known pandas issue that logs a warning about _timelex <https://github.com/pandas-dev/pandas/issues/18141>__, and it will show as a warning until it is fixed in pandas. Please ignore this warning for now.

::

    DeprecationWarning: _timelex is a private class and may break without warning, it will be moved and or renamed in future versions.

Prepare a Dataset

::

Debugging

Test Algos

The fastest way to run algos is to specify a 1-day range:

::

sa -t SPY -s $(date +"%Y-%m-%d) -n $(date +"%Y-%m-%d")

Test Tasks

Most of the scripts support running without Celery workers. To run without workers in a synchronous mode use the command:

::

export CELERY_DISABLED=1

::

ticker=SPY
publish_from_s3_to_redis.py -t ${ticker} -u integration-tests -k trexaccesskey -s trex123321 -a localhost:9000 -r localhost:6379 -m 0 -n integration-test-v1

Deploy Fork Feature Branch to Running Containers

When developing features that impact multiple containers, you can deploy your own feature branch without redownloading or manually building docker images. With the containers running., you can deploy your own fork's branch as a new image (which are automatically saved as new docker container images).

Deploy a public or private fork into running containers

::

./tools/update-stack.sh <git fork https uri> <optional - branch name (master by default)> <optional - fork repo name>

Example:

::

./tools/update-stack.sh https://github.com/jay-johnson/stock-analysis-engine.git timeseries-charts jay

Restore the containers back to the Master

Restore the container builds back to the master branch from https://github.com/AlgoTraders/stock-analysis-engine with:

::

./tools/update-stack.sh https://github.com/AlgoTraders/stock-analysis-engine.git master upstream

Deploy Fork Alias

Here's a bashrc alias for quickly building containers from a fork's feature branch:

::

alias bd='pushd /opt/sa >> /dev/null && source /opt/venv/bin/activate && /opt/sa/tools/update-stack.sh https://github.com/jay-johnson/stock-analysis-engine.git timeseries-charts jay && popd >> /dev/null'

Debug Fetching IEX Data

::

ticker="SPY"
use_date=$(date +"%Y-%m-%d")
source /opt/venv/bin/activate
exp_date=$(/opt/sa/analysis_engine/scripts/print_next_expiration_date.py)
fetch -t ${ticker} -g iex -n ${ticker}_${use_date} -e ${exp_date} -Z

Failed Fetching Tradier Data

Please export a valid TD_TOKEN in your compose/envs/*.env docker compose files if you see the following errors trying to pull pricing data from Tradier:

::

FAQ

Can I live trade with my algorithms?

Not yet. Please reach out for help on how to do this or if you have a platform you like.

Can I publish algorithm trade notifications?

Right now algorithms only support publishing to a private Slack channel for sharing with a group when an algorithm finds a buy/sell trade to execute. Reach out if you have a custom chat client app or service you think should be supported.
