Example order book

Run

Locally

go mod download
go build -o ./bin/book; \
DB_PATH=bin/data.sqlite ./bin/book <input.csv> <output.csv>

Docker

docker build  -t orderbook .

# create the folder with the input
mkdir -p ./dockerdata
cp -rf interfaces/cli/fixtures/1_input_balanced_book.csv ./dockerdata/input.csv

docker run --name orderbooking -v $(pwd)/dockerdata:/data/user orderbook

Test

go fmt ./...
go test ./...

TODO

• "top of book" should be saved on the repository (easier / faster fetch)
• match and trade
• test domain order
• more tests overall

Notes

• Used a pattern based on DDD so that the code is more readable and manageable
