As a long time gamer, I've benefited from the hard work of many others out there who took the time to make spreadsheets of useful info for a lot various games. I didn't see one for trading in Everspace 2, so I decided it was my turn to give back.
It's still a work in progress but you may find it useful, I definitely did, especially when I wanted to make a quick 100k in the late game.
Enjoy :)

Prices do fluctuate at times throughout the universe but they usually stay pretty close to what they normally are.
Any incorrect numbers are likely due to price fluctuations.

I put in simple functions to automatically mark the lowest and highest prices I found for each trade good and anyone may feel free to make a copy and change values to whatever prices exist in your game.

Prices, locations and goods available are current as of Everspace 2 release.

*Important* not all goods are available everywhere, these numbers were acquired by going to each merchant with at least 1 of each item and recording the prices at that location.

Thanks to Bùi Bảo for catching the error at Athor Orbit - I had entered nano fibers at 492, they correctly identified the error and correctly stated it should be 188. The sheet has been updated with the correction. - July 5, 2023
