Contributing

Bug reports and pull requests are welcome. This project is intended to be a safe, welcoming space for collaboration, and contributors are expected to adhere to the Contributor Covenant code of conduct.

Adding an exchange

Add a new driver (see the examples)
Add the driver alphabetically to drivers/index.js
Add a new fixture (use the record option of the CLI 'tickers' command)

Single API calls are highly preferred. When adding an exchange be aware of the base and quote. A driver should at least support base, quote, close and baseVolume or quoteVolume. And optionally open, high, low, ask, bid, baseName, baseReference, quoteName and quoteReference.

Listing requirements

Before we approve your pull request, we’d like to review the exchange and check if it meets our listing requirements.

Ticking off all the boxes? Cool! Send us your listing request at info@coinranking.com and include your daily trading volume + a link to your platform. We will then review your exchange ASAP.
