Project structure

System consist from multiple independent processes that may be run on different node.
Communication is implemented on top of various message queues on top of redis.
Redis is also used as distributed caching layer - to reflect actual balance across all exchanges.
Data in queues usually pickled.
Persistence for historical data - postgres.
Alerting is implemented on top of Telegram messenger.
CLI management is done manually using scripts within this project.

NOTE: Web based UI and data scrapping framework from various resources are NOT part of this repo.

Terminology

  • bot - arbitrage process that trade single commodity between exactly two exchanges
  • order - what bot is placed to markets
  • trade - what was actually executed at markets, single order may be closed by multiple trades

Key services:

  • telegram notifier - watch message queues and forward messages based on their severity to corresponding Telegram channels
  • balance_monitoring - update cached values of balances for all currencies for all exchanges in portfolio All trading processes validate time of last update and will immediately stopped if it expired.
  • expired order processing - due to many reasons order placed by bot may be not closed in time, this service re-process them trying to minimise loss
  • failed order processing - timeout, exchange errors and ill fate may lead to situation that we got errors as result of order placement request. This service carefully check current state of order: whether it was registered within exchange or not, whether it was fulfilled or not.

Data analysis:

  • order saving - save all orders that were placed by arbitrage processes into Postgres db
  • bot trade retrieval - retrieve information from all exchanges in regards to recently executed trades.
  • arbitrage monitoring - read tickers for all supported currency across all exchanges and issue a telegram notification about direct arbitrage opportunities

You may find all available services under services packages.

DEPLOY - HOWTO

Prerequisites:

Node with data and cache:

  • redis in place
sudo service docker start
cd ~/crypto_deploy/redis
# NOTE: you may want to edit path to mounted volume for data persistence 
sudo docker-compose -f redis_compose.yml up
# NOTE: redis IP is hardcoded there:
python redis_queue.py
  • postgres in place with proper schema and data:
sudo service docker start
cd ~/crypto_deploy/postgres
# NOTE: you may want to edit path to mounted volume for data persistence
sudo docker-compose -f docker-compose-postgres.yml up
psql -h 127.0.0.1 -Upostgres -f schema/schema.sql
psql -h 127.0.0.1 -Upostgres -f schema/data.sql
  • data retrieval & nodes with bot processes:
yum groupinstall "Development Tools"
pip install -r requirements.txt
  • copy common_sample.cfg to common.cfg and update it with proper public IP addresses and domain names
  • make sure that firewall rules at aws allow incoming connections from bot nodes to data node

Deploying data retrieval services

Will deploy:

  • order_book, history, candles,
  • arbitrage notifications based on tickers
  • telegram notifications
python deploy_data_retrieval.py

Deploying arbitrage bots

  1. verify settings at config file: more deploy/deploy.cfg
  2. Initiate deployment processes python deploy_arbitrage_bots.py deploy/deploy.cfg

How to run dedicated services from subfolder:

python -m services.telegram_notifier

Kill ALL processes

ps -ef | grep arbitrage | awk '{print $2}' | xargs kill -9 $1

or just

pkill python

Kill ALL screens with all session MacOs

screen -ls | awk '{print $1}' | xargs -I{} screen -S {} -X quit

screen -ls | grep -v deploy | awk '{print $1}' | xargs -I{} screen -S {} -X quit based on https://stackoverflow.com/questions/1509677/kill-detached-screen-session

alias cleanscreen="screen -ls | tail -n +2 | head -n -1|cut -d'.' -f 1 |xargs kill -9 ; screen -wipe"

alias bot_count='ps -ef | grep python | wc -l'
alias bot_kill='pkill python'
alias bot_stop_screen="screen -ls | tail -n +2 | head -n -1|cut -d'.' -f 1 |xargs kill -9 ; screen -wipe"

Rename existing screen session

screen -S old_session_name -X sessionname new_session_name

REMOTE_ACCESS:

ssh -v -N -L 7777:192.168.1.106:5432 86.97.142.164 -i .ssh/crptdb_sec_openssh -l dima -p 8883
ssh -i .ssh/crptdb_sec_openssh -v [email protected] -p 8883
ssh [email protected] -p 8883

MacOs dependencies:

pip install python-telegram-bot --user
