Go - Between

Go Report Card License MIT Go Doc Release

A distributed fault-tolerant order book matching engine.


  • Limit orders
  • Market orders
  • Order book depth
  • Calculate market price for a given quantity
  • Standard price/time priority
  • Distributed and fault-tolerant based on Raft Consensus Algorithm

Download binaries

You can download a pre-built binary here.

Build from source

First, install Go.

Next, fetch and build the binary.

go get -u github.com/danielgatis/go-between

How to init a cluster

First of all, start a new cluster:

go-between start --id=1 --market=USD/BTC --port=3001

And add a two more nodes:

go-between start --id=2 --market=USD/BTC --port=3002 --join=localhost:3001
go-between start --id=3 --market=USD/BTC --port=3003 --join=localhost:3001

API Endpoints

Each node publishes a REST API with the following endpoints.

Adding a new limit order

curl --request POST \
  --url \
  --header 'Content-Type: application/json' \
  --data '{
	"orderId": "1",
	"traderId": "1",
	"market": "USD/BTC",
	"side": "sell",
	"quantity": "1",
	"price": "400.00"

Adding a new market order

curl --request POST \
  --url \
  --header 'Content-Type: application/json' \
  --data '{
	"orderId": "2",
	"traderId": "1",
	"market": "USD/BTC",
	"side": "sell",
	"quantity": "1",
	"price": "400.00"

Cancel an order

curl --request DELETE --url

Calculate a market price

curl --request POST \
  --url \
  --header 'Content-Type: application/json' \
  --data '{
	"traderId": "1",
	"market": "USD/BTC",
	"side": "sell",
	"quantity": "10"

Get the order book price depth

curl --request GET --url

Get the full order book
