I haven't really plugged my site in a while but with Beta 3 about to arrive and the new features I thought I'd better raise it's profile a little so new folks know it exists. It's been around since Alpha and has over 2300 registered users.
The site allows you to query a database of community sourced trading data in a variety of ways as well as plotting routes between systems.
Check it out at http://www.elitetradingtool.co.uk/
Route planning is now done in the browser rather than on the server which should provide a large boost to performance. The first query per system will be a little slow as your PC processes the route map but subsequent requests will be faster.
System location data is direct from edstarcoordinator.com so it will automatically improve as the community gathers data.
Users that have achieved the rank of Expert can now add all missing commodities to a station with a single click. This should make populating new stations much faster.
New dark design more in keeping with the Elite: Dangerous theme and because lots of users said the white theme was too bright when playing in the dark.
Station and system selectors moving to an auto complete based system as drop downs were getting too fiddly with so many locations.
The route planner on the trade calculator has returned after it's short hiatus.
I'm working on an API for the site, some functions have already transitioned to it but there is a lot to add and test before I release any details.
The next iteration of the site will be focusing on admin improvements to help data entry and checking.
