I created a website that provides a user interface and trading algorithm for EDDN/EDDB trade data. It takes a different approach than most existing tools by estimating trade time and maximizing profit/hour. It's called Elite Trade Net. Check it out: http://etn.io

Select your start system/station, pick your ship and set your starting budget. Then follow one of the recommended routes and profit. Use any EDDN-compatible tool to upload live trade data to ETN. I like EDMC. It uploads data from your current station with a single click using the web api provided by Frontier. Other similar tools are discussed here.

Let me know if you have any questions or run into any issues. ETN should run on any HTML5-capable browser and works great on mobile devices.
