can you by any chance tell me how? I can't seem to figure out where to find the page that does this..
The Trade Overview panel containing the information.
Open it and click under Find Location the Best Sell button.
Then select the resource at Select Item, you want to sell.
Right after the selection, stations will be displayed in the list below.
You can sort it by distance or price to find a suitable station for selling.
TCE can only display stations, which are already in your database. You can collect stations either by visiting or adding them through the EDDB-Relay.
If you didn't have any station in your database (because you are new to TCE), open the Extension tab at the launcher of TCE and hit the Create Database button.
You can edit the preferences of sphere range and distance from main star before to fit your needs. Use the default values, if you are unsure.
This is only required, if you have a clean database or you have changed the region, leaving the sphere of stations created before.
Thereafter you have to update the commodity prices of the newly added or already available stations at your database by clicking the Update Trade Stations button.
This has to be done only once a day.
