What happens when you have large quantities of metal, but not enough minerals? You are forced to store the metal until you obtain the other necessary resources. Not anymore! The Trade center represents a group of leading traders worldwide, who in no time exchange resources at present rates. Thus saving valuable time, which can be effectively used for constructing new ships, for example.
Each planet can have one Trade center. Upgrading the building reduces the traders' commision and thus provides more favorable exchange rates.
Each player can put an offer with max ratio 1:1,2, i.e. you can offer 1000 metal for 800-1200 minerals. There is a commission if your offer is unprofitable for the buyer (the commission is max. 10%).
When an offer is added, it can't be revoked in the next 6 hours. After that it can be revoked. When revoked for 6th to 24th hour, the interest is from 50 to 0%. If the offer is revoked after 24 hours, there is not interest about this offer.
When players accept the offer, he gets his part at the same moment. The seller has the right to withdraw his part, whenever he wants. If the seller does not pull resources to 48 hours, they will automatically be charged to the planet.
