A most dangerous game

My first gamble with the stock market was not as nice as my first time gambling in a casino. In the casino, I won a few dollars, but my investment in Ford (back in '06 or so) put me back about $200. But gambling is addictive and I'm addicted.

You should notice that there are more buy/sell lines near the right end of the graph. That's because I'm buying and selling more often now. Soon I will be a day trader. Let's zoom in on the end:






















The last day on this plot looks like the price was just going up and up, but actually I was buying low and selling high. To see how this could have worked, you can check out the detailed intraday prices here.
