Description
Left click: buy. Right click: sell. Read on for details! The number at the top is your current cash. Each trend floats up and down. The graphs are always adjusted to fit in the screen. The 3 numbers written in white are (top to bottom): the highest displayed value, the current value, and the lowest displayed value. When you buy some stock, a number (conveniently coloured in red or green depending on your luck) appears in the center. It displays the average price you bought the stocks for, and, in parentheses, the number of stocks you own. When you sell, you are selling the last stock you bought. When a stock reaches 0 value: bankrupt! That stock will never rise again. You can still buy/sell at 0, if you wish... If i am not wrong, in a brownian motion (as the motion of the stocks in this game) you eventually reach 0 with 100 percent probability. So, how rich can you get before that?
