Ok, let's have a look at the perfect trade model:
You produce goods and sell them to the highest bidder. So far so good. Your POPs buy from the cheapest provider. Production costs will differ for goods in each country, and so will the available cash. Now, you plot for every of the thousands of POPs every day from where they buy their goods, comparing all the prices for all the POPs respectively. Don't forget to factor in trade policies, shipping distances, tarriffs, subsidies, embargoes, blockades....
...and then I dare you to program it and have it run at reasonable speed.
I hardly think an Afghan peasant would buy grain from England just because it was dirt cheap...
But I agree with the poster above me, at least some feature to give goods to my allies would have been nice...
