查看“阿布答疑：我可以跟单赚钱吗？”的源代码

许多年前，我花费3000美金从一个公司购买了一个交易策略，同时订阅了各种专家的分析频道以及咨询热线，可最后都无疾而终。你一定也在电视上听到过某某"专家"说：“黄金价格要涨”、“原油价格要跌”，或者“股市要涨”等等。你以为你掌握了盈利门路？实际上，你无法从中获利。我经常说：“市场大约有10%的时间处于强劲趋势中，在那种情况下，你只能买进或只能卖出，而剩下90%的时间是盘整状态，在盘整区间里，保持单边行情的看法只会让你亏钱。但如果你正确地管理你的交易，你任何时间买进或卖出都可以获利”。

I remember years ago — I forget the name of the company; maybe it was Essex Trading — I paid them $3,000 for formulas.  I used to subscribe to all kinds of guru newsletters and hotlines, and a lot of it is just a total waste of money, right? If you see some clown on television saying, “Gold is going up,” or “Crude oil is going down,” or “The stock market is going up,” you cannot make money off of that because you hear me say this pretty regularly:  About 10 percent of the time (in strong trends) you can only make money buying or only make money selling.  90 percent of the time (in trading ranges), you can buy or sell at any point and make money, if you manage your trade correctly.
