BitcoinExchangeFH - Bitcoin exchange market data feed handler

BitcoinExchangeFH is a slim application to record the price depth and trades in various exchanges. You can set it up quickly and record the all the exchange data in a few minutes!

Users can

  1. Streaming market data to a target application (via ZeroMQ)
  2. Recording market data for backtesting and analysis.
  3. Recording market data to a in-memory database and other applications can quickly access to it.
  4. Customize the project for trading use.

Getting started

It is highly recommended to use pip for installing python dependence.

pip install bitcoinexchangefh

If your operation system has pythons with version 2 and 3, please specify pip3 for python 3 installation.

pip3 install bitcoinexchangefh

Destination

Applications

You can write your application to receive the market data via ZeroMQ socket.

BitcoinExchangeFH acts as a publisher in the Publish/Subscibe model. You can open a TCP or inter-process traffic.

For example, if you decide the data feed is subscribed at 127.0.0.1 at port 6001.

bitcoinexchangefh -zmq -zmqdest "tcp://127.0.0.1:6001" -instmts subscriptions.ini

According to zmq-tcp, please provide "127.0.0.1" instead of "localhost" as the local machine destination.

If the data feed is subscribed via inter-process shared memory with address "bitcoin".

bitcoinexchangefh -zmq -zmqdest "ipc://bitcoin" -instmts subscriptions.ini

Sqlite

No further setup is required. Just define the output sqlite file.

For example, to record the data to default sqlite file "bitcoinexchange.raw", run the command

bitcoinexchangefh -sqlite -sqlitepath bitcoinexchangefh.sqlite -instmts subscriptions.ini

Kdb+

First, start your Kdb+ database. You can either choose your own binary or the binary in the third-party folder.

q -p 5000

Then connect to the database with dedicated port (for example 5000 in the example).

For example connecting to localhost at port 5000, run the command

bitcoinexchangefh -kdb -kdbdest "localhost:5000" -instmts subscriptions.ini

MySQL

To store the market data to MySQL database, please install mysql-server first. Then enable the following user privileges on your target schema

CREATE
UPDATE
INSERT
SELECT

For example connecting to localhost with user "bitcoin", password "bitcoin" and schema "bcex", run the command

bitcoinexchangefh -mysql -mysqldest "bitcoin:bitcoin@localhost:3306" -mysqlschema bcex -instmts subscriptions.ini

CSV

No further setup is required. Just define the output folder path.

For example to a folder named "data", you can run the following command.

bitcoinexchangefh -csv -csvpath data/ -instmts subscriptions.ini

Multiple destination

Bitcoinexchangefh supports multiple destinations.

For example, if you store the market data into the database and, at the same time, publish the data through ZeroMQ publisher, you can run the command

bitcoinexchangefh -zmq -zmqdest "tcp://localhost:6001" -kdb -kdbdest "localhost:5000" -instmts subscriptions.ini

Arguments

Argument Description
mode Please refer to Mode
instmts Instrument subscription file.
exchtime Use exchange timestamp if possible.
zmq Streamed with ZeroMQ sockets.
zmqdest ZeroMQ destination. Formatted as "type://address(:port)", e.g. "tcp://127.0.0.1:6001".
kdb Use Kdb+ database.
kdbdest Kdb+ database destination. Formatted as "address:port", e.g. "127.0.0.1:5000".
sqlite Use SQLite database.
sqlitepath SQLite database file path, e.g. "bitcoinexchangefh.sqlite".
mysql Use MySQL.
mysqldest MySQL database destination. Formatted as "username:password@address:host", e.g. "peter:[email protected]:3306".
csv Use CSV file as database.
csvpath CSV file directory, e.g. "data/"
output Verbose output file path.

Subscription

All the instrument subscription are mentioned in the configuration file subscriptions.ini. For supported exchanges, you can include its instruments as a block of subscription.

Argument Description
(block name) Unique subscription ID
exchange Exchange name.
instmt_name Instrument name. Used in application, e.g. database table name
instmt_code Exchange instrument code. Used in exchange API
enabled Indicate whether to subscribe it

Market Data

All market data are stored in the dedicated database. For each instrument, there are two tables, order book and trades. The order book is the price depth at top five levels. They are recorded under the table names of

exch_<exchange name>_<instrument name>_snapshot

Output

Each record (in any output format e.g. CSV/SQLite/KDB+/etc) indicates either a new trade or a change in the order book.

The column definition is as follows:

Name Description
trade_px Last trade price
trade_volume Last trade volume
b<n>, a<n> Best bid and ask prices, where n is between 1 and 5
bq<n>, aq<n> Best bid and ask volumes, where n is between 1 and 5
update_type Update type. 1 indicates price depth update, and 2 indicates trade update
order_date_time, trade_date_time Last update time for the price depth and the trades

Library

If you do not like the console application and would like to write your own, you can use it as a library.

    from befh.exch_bittrex import ExchGwApiBittrex as Feed
    from befh.instrument import Instrument
    instmt = Instrument(exchange_name="Bittrex", 
                        instmt_name="LTC/BTC",
                        instmt_code="BTC-LTC")

    # Get the order book depth
    depth = Feed.get_order_book(instmt)

    # Get the trades
    trades = Feed.get_trades(instmt)

where parameter instmt_code is the exchange API instrument code.

Inquiries

You can first look up to the page FAQ. For more inquiries, you can either leave it in issues or drop me an email. I will get you back as soon as possible.

Compatibility

The application is compatible with version higher or equal to python 3.0.
