Yes, but I've been reading all these threads and they say you can't trade with supply range.
I have seen some people talk about the need to have supply range to protect trade (which makes sense) but you can establish a protectorate to fulfill the supply need. You can trade where your merchants are (so trade range is important for sending merchants, since you can't protect trade where you don't have a merchant, or own a territory). Supply ship range is used to keep your naval attrition down (as well as to protect trade). Originally posted by Xandurz:You can trade in your trade range.
