I wanted to see what would happen if you let a stock run through the waves of time. It's designed to sell after the price goes up by 25%, and then rebuy when the price is 80%.
The glaring flaw is that if it goes into a stock that just tanks, well, you lose all your money.
I have the stock purchase go on even minutes because I wanted to make sure the orders didn't go into the negative. After working for EMC for so many years, part of me wished I did this, so I wanted to see what happens if I listend to my gut and put the money in. :)
