Quote from Josette:
I like to think of the stock market as a clothing store..
Why buy a full priced t-shirt that is guaranteed to go on sale?
You're losing money because you buy when the stock is at a high, and selling for a loss when the stock is down and worth less.
Start buying low and selling high. The least you can do is buy low and hold until the stock goes up. But if you really want to profit then use an automated trader.
