There are two sure ways to go broke trading a market: picking tops and bottoms based on valuations, and taking trades based solely on indicator readings. When did the Japanese market become overvalued when the Price divided by the Earnings ratio was 30, 40, 50, 60, 70, or 80 to 1? When did silver become over-valued? The previous high before 1978 was $6.40, yet it rose to over $50 per ounce. When attempting to sell a top, focus on an intraday time interval suitable to the market traded. I use 1, 3, and 5 minute charts to trade the S&P mini with a pattern recognition reversal system. Any trader can find an indicator to agree with an opinion or analysis, but it must be confirmed with valid price action. A market is never too high to buy despite the over bought indicator, but may be too cheap to sell based on intrinsic valuation. The trader who thinks he can pick tops and bottoms has a built-in self-defeating character flaw. That trader is selfish. He wants it all, from top to bottom, or Bottom to top. Selfish is different from greed. Greed never has enough. The greedy trader stays in too long hoping for more. The selfish trader wants it all for himself, not willing that anyone else can have their piece of the market.
