理解止损

2015-04-21 21:17:31

如果您想在外汇交易中成为一个盈利的交易员，那么你理解止损对你来说就是非常重要的。

好的交易员在接受失败和承认他们已经犯了错时不会犹豫。你不可能每次选择的交易都是正确的，而你越早意识到这点，你就能越早降低你的损失。

设想一个交易员以30美元的价格购入一支股票，希望它能长到34美元，却看到价格突然下跌。这时候决定何时卖掉这只股票并承认自己是错误的就非常重要了。如果交易员在股票刚刚跌倒29美元时就卖掉它，那么损失就很小。而且，小损失意味着你在接下来的时间还会有足够的资金进行交易。

在交易之前确定风险和回报是非常重要的。以上面提到的情况为例，如果那个交易员的预测是正确的，那么交易员就会有四点的收益。而预测是错误的，他会有一点的损失。也就是在这个案例中汇报和风险的比例是四比一。

现在让我们假设这个交易员在四单交易中正确了两单，这就意味着这个交易员赚了8点，损失了两点。在这种情况下，这个交易员在正确率50%的情况下获得了6点的收益。即使交易员只有四分之一的正确率，他还是能拿到一点的收益。

交易员应该一直维持一个四比一的收益和风险比例。你绝不能使用二比一的比例。一个二比一的比例很可能意味着你对市场的走向根本没有判断。许多时候市场都是突然转向，许多交易员都是手握资金而不重新进行交易。

你容易在市场环境下的纸上模拟交易中发现。结果会向你展示你不把钱投入这些交易中是个正确的决定。我们要记住的最重要的事是选择不交易和交易正确都是正确的方法。无纪律交易的结果通常会招致损失。

Understanding Stop Losses

A proper understanding of stop loss in Forex trading is essential if you want be a winning trader. Good traders will not hesitate to accept defeat and acknowledge that they made a mistake. It is impossible to be right every single time and the sooner you accept this, the sooner you will start minimizing your losses.

Namely, imagine that a trader purchases a stock for the price of 30 dollars, expecting it to rise to 34 dollars, only to see it go down abruptly. Deciding when to sell and when to acknowledge that a mistake has been made is of crucial importance. If the trader sells the stock as soon as its price falls below 29 dollars, the resulting loss would be small. Moreover, minor losses mean that there will still be money to trade on the following day.

Determining the risk and reward ratio prior to assuming a position is obligatory. If we take the above-mentioned case, had the prediction turned out to be right, the trader would have won four points. A wrong prediction would have implied losing one point. This means that the risk and reward ratio in this specific case is four to one.

Now, let us assume that the trader was right in two out of four trades, i.e. fifty percent. That means that the trader won eight points (two times four points) and lost two points (two times one point). This gives us an overall profit of six points and the trader only guessed fifty percent of the trades. Even if the trader was so bad that they were only right in twenty-five percent of the trades, there would still be a profit of one point.

Traders should always maintain a four to one risk and reward ratio. You should never go for a two to one ratio. A two to one ratio means that most likely there is no telling what direction the market will take. Most frequently the market moves sideways and a great number of traders squander their money instead of just refraining from trading.

You can easily check this out for yourself by simulating trades on paper in these market circumstances. The results will show you that you made the right choice not to put your money on those trades. The most important thing to remember is that choosing not to trade and being right is also a way of winning. Being undisciplined with regard to this fact will ultimately result in loss of money.
