it's not balance to use trade spot. We need to send resource between colonies.
My opinion is add function in Trade platform
level 1 can send 1000 resources
level 2 can send 2000 resources
x level * 1000
If we have resources, why we have to sell and buy from other or have resource in the colony that wont use?
Yes, should be able to fill up a few ships and fly the goods over. If in an Alliance (fond memories as I am not in one again yet) then one can get round the restriction b selling to a friendly third party and buying back.
