well Ranholn, effect is what you make it young grasshopper
. I'm using it more to represent parallels to real life companies.
It's setup as a game, but it's not competitive (at least I'm not playing it competitively). I setup a portfolio 'DSE' which is just all stock of an NYSE SPDR, kind of to represent the total amount of stock available and total price. You could use your real life price, or an average if you have multiple representing one companies, to price your DSE shares, and then you can sell your shares at that price since you've already established how much you have available. Just as a thought.
Actually, multiple companies for one company isn't a bad idea either (since there are thousands of RL companies), because I was actually trying to think of a solution for the Mercantilist Brewing Co. since they have more than just beer.
Dysanii, you can sell off stock I think.
