multiple stocks to buy/sell. the idea is to buy low and sell high. uses kudos as a currency, ill let someone else help with the details.
scenario:
I have 5,000,000 kudos, and i decide i want to buy shares in google. each google share costs 250,000 kudos at the current rate. I spend all my kudos minus a 10% transaction fee and end up with 18 shares. the shares skyrocket and end up at 750,000 kudos each (for those bad at math that's 3 times the price) I sell all my shares (selling as many as I can so i do not hit the 5,000,000 kudos limit, or many have it so i can put it straight into my clans treasury?) for a total of 13,500,000 kudos minus a transaction fee of 1,350,000 kudos leaving me with a total of 12,150,000 kudos, a whole 7,150,000 kudos richer than before that can be used to buy items from the showroom or be deposited into my clans treasury.
now of course the stocks won't raise that much, but you get the idea.
