Exchange

The Stellar Exchange is the center of the economy. One can buy and sell resurces on it. The currency used are stellars. All prices are player determined. If you sell an item for one stellar and nobody is buying then the exchange will buy it for one stellar. Beginner players will find it especially useful to sell resources that won't be needed until later such as sand and latex and then buy resources they need such as wood or concrete.

Buying or Selling an Item
To get to the exchange go to your planets then hit the top right button. From there you can see how much people are buying and selling items for. If you see "Exch (1)" that means the exchange is buying that item for one stellar without a player involved. This is done instantly. You can see in real time the prices of items go up and down. To buy or sell an item click buy or sell next to your item (or scroll to it using the arrow buttons). Then enter how many you want to buy and then how much you are willing to pay each or sell each. It is advised to look at current market trends to see what prices are likely to be accepted, but you can enter however much you want. Then click "Ok" to create the transaction. The transaction may be completed instantly or it may take some time depending on market demands.

Investing
Investing can be a tricky and dangerous business, but the rewards can be massive. The prices on the exchange fluctuate depending on what players need. If you buy an item when the price is low you can sell it when it is high to make a profit. However the price could drop and leave you with resources you do not want. It is advised not to invest all of your resources.
