1870's Stock market

I think that Mr. Coyle's tip number 2, you must spend money to make money, and tip number 7, a fool and his money are too soon parted, describes how the game went for me the best. I spent a lot of money and in the beginning I also made a lot of money. Later on, as one of the stocks went up really high, I thought that it couldn't go any higher up and so, i sold it. Then, when I sold it, the price went way higher up, and I lost money. This was foolish, I shouldn't have sold my best stock. The one tip I thought really worked, but I didn't really follow and which doesn't represent how the game went for me is tip number 1, buy low..... sell high. This really is the major point of selling and buying stocks. It is smart to buy stocks at a low price, and then wait for it to go up, and then sell it again. I didn't listen to this rule, thought, now I think I should have.
