I have traders, trading with my partner. When the game ends, the summary is not what I would have expected. See the image below.
I have my traders (I'm Steve) selling food and buying mostly metal. Yet the image below shows 0/0 for the metal exchange. Clearly, I don't understand how this works.
Looks like the green numbers stand for units sold and the pink number for units bought (bartered). Correct?
--------------------------------------------------------------------------------------------
Since I am selling food, I would assume that the pink number 2800 represents the amount of food sold.
The summary says that I have a barter efficiency of 78%. So I have sold units of food 2800x.78 = 2184 - 1943 (wood) = 241 - 243 (stone) = -2 (round off error).
In summary, I have sold 2800 units of food to "buy" 1943 units of wood and "buy" 241 units of stone. But nothing for metal?

What does trade income translate into, in terms of the game? My total income was 3513 units.
Any further insight into this process?
