EVE Market Data Relay (EMDR)

EVE Market Data Relay (EMDR) is a super scalable, highly available firehose of real-time market data. For those that wish to record price and history data as it comes in, EMDR will help you do so as efficiently and reliably as possible. EMDR’s data feed is open to the public, and is developed as an open source project.

EMDR may appeal to you if:

  • You need real-time access to market data, as soon as possible. Perhaps for sending out price/inventory level alerts, notification of lucrative trade routes, or real-time charts and graphs.
  • You want to record prices over time.
  • You want the absolutely most complete set of data that you can get.
  • The effort and overhead of getting large amounts of direct player uploads to your site is too much to bear.

EMDR’s primary goals are:

  • Ensuring that all market sites have access to player-uploaded market data.
  • Extremely high reliability.
  • Minimize expense to those running EMDR (shared burden).
  • Minimize expense to those consuming the feed (bandwidth).
