i've seen a mistake at the second "Basic Information/The Market/Page2" first you say that you change iron/coal, but then at the description you write gold/iron...
here a quote:
Quote
If you want to sell 100 000 iron/
coal:
If you do 8 times 1000 gold for iron then you get 353 gold/1000 iron. So if you sell you get 35 300. So the net result is 27 300
If you want to sell 800 000 coal / iron
Do 20 times 1000 iron for gold and you get 483 gold/ 1000 iron. So 386 400 gold. The net result is 366 400.
