[h=3]Trading is a very useful, popular way to make money as a starship Commander.[/h] There are thousands of star systems with commodities markets - and some with multiple markets. Each of these markets exists in a Starport.
The rules are simple and universal: buy goods cheaply, where they are made and there is plentiful supply, and then sell them where prices are high, in a location with a high demand for your cargo.
Supply and demand drives prices galaxy-wide - your every trade contributes to the dynamic market activity. The smaller the local market, or the rarer the commodity, the more easily you and friends can work together to influence prices for your own benefit.
Commodities range widely in type depending on the system you are docked at, from domestic goods to raw minerals to agricultural products and weapons.
The majority of things you can trade are above-board, b
ut there are narcotics and slaves too, which are illegal in different jurisdictions, so you'll need to put your stealth skills to the fore to successfully trade in those.
You can make a healthy profit as a smuggler or an honest trader. But beware the pirate looking to make their own profit - from you.
