I am in a station and want to look around for the best trade deals
Give a flow diagram what to do
First, to understand the functions of the panels of TCE, please refer to the wiki. There is a link to it in the main post. There you will find the explanations for all panels.
Set the "Auto-Destination" mode in TCE to get suggested trades to you. The best way to see the suggested trade with a station in the set trading range is in the trade overview panel. The Trade Advisor lists all the goods you should buy at the docked station to sell at the destination station.
After purchase, set a route to the destination station in-game and TCE will display the closest star system to the destination. The Waypoint panel shows you the necessary jumps and their range from system to system to get an overview.
As soon as you reach the target station, TCE will show you a new trade, which will take you to another station, etc. This method ensures you the highest yields without having to search specifically for profitable routes.
However, you will get the highest returns from two-way routes. To do this, select the "Route Finder" panel. Here you will be shown the best routes based on the stations available in your database. Select appropriate filters for the route search, if necessary. The "Data-Age" filter is very important here, because the older the data in your database is, the more likely it is that the profits shown will deviate from the actual ones. The data should therefore not be too old. A value of 1-3 days would be recommended.
When you have chosen a route, click on Start Trade Route. After that, TCE will switch to route mode and just switch back and forth between the two stations once you arrive, or direct you to the nearest of the two stations to start the route.
There are also some great videos, you can find the links in the main post.
I hope this helps you get started with TCE and see its potential to assist you.
