第一个步骤是买什么或卖什么，也就是说在什么市场交易。如果你在非常有限的市场交易则可以明显的减少的失去跟随趋势的机会。同时你也不会想在交易量非常小和趋势不明显的市场交易。另外一个原因是在一个由少数寡头控制的市场进行交易也不会是一个好的交易。

什么时候买或卖
决定什么时候去买或卖的方法就是确定什么时候开始上升趋势或下降趋势。有很多方法可以用来确定趋势。一些方法是依靠高点或低点的突破，一些方法则是使用穿越移动平均线，另外一些则是通过价格的形态发现顶部或底部。所有的这些方法都是用来发现趋势的开端。
大多数试图抓住趋势起点的系统成功率都比较低。这就是遵循系统进行交易比较困难的原因之一。交易几个月甚至一年都没有发现一个好的明显的趋势也是有可能的。经历一段比较长时间的失败后，大多数交易者都会对他们的系统产生怀疑并且在交易的时候变得犹豫不决。Howtobuyorsell

一旦信号产生，如何买卖是一个非常重要的技术步骤。这一点对于大资金帐户进出市场非常重要，因为它们的买卖金额太大了以致于引起市场的波动。经过常年交易，由于糟糕的入场技术造成的大量的小损失。（这句翻译不好）
How much to buy or sell
买或卖多少（头寸管理）

关于买卖多少的决定是绝对重要的，但是经常被大多数交易者忽略或者没有被妥善处理。一个普通的（但是非常糟糕）的方法是每次交易买数量的头寸，一些交易者每次买固定金额的头寸。

解决交易中买多少或卖多少的两个方面是多品種交易（交易多个品種）和风险管理

在追随趋势中，多样化交易试图把风险分散许多交易同时通过增加捕捉到趋势的机会来增加利润。合适的多样化需要在很多不同的交易中下类似或同样的赌注

风险管理实际上是关于不要下太多赌注，否则在好趋势到来之前已经输掉所有的钱。针对这个原因，买卖多少是交易最重要的一个方面。在每次交易冒太大的风险，实际上是增加暴仓的机会，甚至在有一个非常有效的交易风格的情况下。

我们都听过这样的格言：斩断亏损，让利润奔跑。但是它和人不愿意犯错的本性相抵触。对于大多数人来说，坚信一个已经有损失的交易会转向要比接受这样的交易已经没有意义需要止损要容易得多。

止损是非常关键的。从长期来看，如果一个交易者不会止损就不会成功。几乎所有得失去控制和冒巨大的健康和财务风险的交易都可以造成巨大的损失，而其原因仅仅是在它们的损失很小的时候没有止损。

关于止损的最重要的事情需要在你按某个价位建立头寸之前事先制定一个止损位。一旦市场移动到你的止损位，你要第一时间止损。如果在这个时候犹豫不决，最终会造成灾难。

总结：
如果你有一个机械系统，而且你坚持按照系统进行交易，则可以轻易排除由于长时间的亏损或者一次大的盈利二带来的非常剧烈内心情绪波动。（很明显，这種情绪波动是非常不利于交易的偶注：）
