A cryptocurrency tool to help find and act on arbitrage opportunities.

This work is an EDA final project by Adam, Maddie, Peter, Tim and Tyler in the Harakeke-2018 cohort.

Arbitrage is the simultaneous buying and selling of assets (securities, currency, cryptocurrency, commodities) in different markets. The trader can then take advantage of differing prices for a particular asset.

The DeltΔge name was chosen for this project because:

• delta is used by many disciplines to represent a difference or change
• the name is a contraction of delta and arbitrage
• deltage is a Danish word, meaning 'to take part' or 'to participate'

How it works

DeltΔge currently fetches data at 10 second intervals using standard API calls from these three Cryptocurrency Exchanges:

1. Bittrex
2. Poloniex
3. Kraken

The incoming data is reformatted to show arbitrage opportunities which are delivered to the client’s browser using web sockets.
