Improved Trade Modules in Avorion: all of them will tell you all they can know about prices.
This is an improved version of the advanced trade module mod (which I fixed to be compatible with the latest Avorion version to date). Every trade module will provide all the information the top-tier version of the trade module can. The only limitation left in place is the number of sectors for which information is stored.
A fixed version that incoprorates the original features with the additions made to the base game regarding to trade is found here: https://github.com/Joeppie/AvorionModFixes/tree/master/improvedtradingoverview-v0.22 (based on: https://www.avorion.net/forum/index.php?topic=2871.0 )
