Stock Market stupidity

Why on earth does it show trades that you cant have? What is the point, To know that if you hadnt pi55ed off Afghanistan you could have got 11.0 for your food instead of 7.5??

Get rid of this silly nonsense at the next upgrade.

Also why have a limit on buying and selling. Someone will always buy/sell your stuff. Ludicrous when you cant sell anything. Always happens middle game plus.
