Igthorn

Igthorn is a batteries-included cryptocurrency trading platform written in Elixir.

Non-comprehensive list of Igthorn's features:

• baked-in backtesting engine that allows to test your strategies against historical data
• "naive" trading strategy
• list and search through current and historical trades, orders and transactions
• view chart representations of your trading and many others

Igthorn is a boilerplate for kick-starting your crypto trading project. It contains everything you need to immediately focus on writing profitable algos instead of worrying about setup, custom framework etc.

It's structured as umbrella app that consist of:

• Ui - GUI - Phoenix frontend allows fine tuning of crypto trading environment using browser instead of raw db queries. Things that can be done via browser include:

• starting/stoping straming on symbol,
• modyfing naive strategy settings
• starting/stoping trading
• starting backtesting
• and others.

• Hefty - Backend - streaming and trading backend supporting Binance consisting of:

• naive trading strategy
• backtesting engine
• business logic used by UI
• and others

Setting up

docker-compose up -d
mix deps.get
cd apps/ui/assets && npm install && cd ../../..
cd apps/hefty && mix ecto.reset && cd ../..

iex -S mix phx.server

Seeding script checks is there api_key and secret filled in config of Hefty. It will perform additional query to binance to fetch current assets' balances.

Usage

After starting the server with iex -S mix phx.server it will automatically go to database and check are there any symbols with enabled streaming and starts streaming for them.

User interface provides a way to start streaming trade events into db under the local url: http://localhost:4000/streaming-settings

There's a column called "streaming" which contains true/false. By clicking on true/false in one of the rows you will flip(enable/disable) streaming for that symbol.

Here's a diagram of processes with 4 streams open:

Enabling streaming will put data in Postgres database called hefty_dev in table trade_events.

Dumping events

To get data out from database into csv file exs script can be used:

cd apps/hefty
mix run priv/repo/scripts/dump-daily-trade-events.exs --date "2019-05-16"

This will create bunch of files in main directory of project (one for each symbol that it has any events in the day).

Naive trader strategy

Single strategy should be provided for people to understand how to implement one on their own.

Naive strategy described in video called "My Adventures in Automated Crypto Trading" by Timothy Clayton

Technical considerations:

• My aim is to keep UI close to Elixir with as minimal Javascript as possible so I definietly prefer to keep going on Liveview route.

• Would like to keep streaming seperate from trading as I would like to allow for multiple strategies running simultaneously.

To do:

• dashboard screen to allow people to have strategies that flag "interesting" symbols (for example volume trading)
• possibly implement different exchanges to allow for strategies like arbitrage and others.

Backtesting

Step 1 - Initialize empty database

cd apps/hefty && MIX_ENV=backtesting mix ecto.reset && cd ../..

Step 2 - Import historical data

There's a CLI script that will download historical files for you. there's about 20 days of data from June (2019-06-03 up to 2019-06-23). To load it you need to specify directory to store csv dumps(script will download them for you) to as well as from and to dates and symbol that you are interested in - example below:

cd apps/hefty && MIX_ENV=backtesting mix run priv/repo/scripts/load-trade-events.exs --path="/backup/projects/binance-trade-events/" --from="2019-06-03" --to="2019-06-22" --symbol="XRPUSDT" && cd ../..

This will give you a little bit over 2.8 million events(20 days of trading data).

Step 3 - Start application in backtesting environment

MIX_ENV=backtesting iex -S mix phx.server

Step 4 - Enable trading on XRPUSDT pair - go to "Naive trader settings" and search for the symbol. Click on "Edit" set budget to some decent amount like 1000 and click "Save". Now click on "Disabled" button to enable trading. At this moment system will listen to XRPUSDT stream.

Step 5 - Now go to Backtesting section chose "XRPUSDT" symbol, select 2 dates (2019-06-03 and 2019-06-09) and click "Submit" which will send all 1 million events through naive strategy trader(s).
