Hedge:
In finance, a hedge is an investment that is taken out specifically to reduce the risk in another investment. Hedging is a strategy designed to minimize exposure to an unwanted business risk, while still allowing the business to profit from an investment activity.
In FOREX, there are two kinds of similar "hedging" strategies:
1, Buy and Sell the same currencies pair, same lots, same timing. Then let it go. While one of those orders goes north, the counterpart will go south. After the winner takes profit, we can wait for the loser turning around. In a yo-yo market, this method works well.
For example, buy 2 lots GBP/USD at 2.0003, at the same time sell 2 lots GBP/USD at 1.9997. While the rate rises up to 2.0053, we close the buy order and take profit 50 pips. Now, the sell order will draw down around 50 pips. Let’s wait for the rate falling down, it will fall down usually, especially in yo-yo market environment. If the rate drops down to 2.0037, close the sell order, the sell order will lose 40 pips. Does it hurt? No. Don’t forget the 50 pips we have taken at the buy order. Totally, we can get 50-40=10 pips. Furthermore, if the rate keeps falling, let’s say down to 2.0027, we can take 50-30=20 pips, etc.
Some people would doubt it... doesn't this "strategy" sound like hedging flat for nothing, just paying double spread? Why bother? Well, they are right, because we forgot mentioning the key point: timing of closing orders. When to close the winning order to set a foundation and when to close the losing order to lock the profit, there are some tricks inside. Experienced traders use technical analysis skills to decide this vital timing. Believe it or not, those experienced traders say that this method helps them screening false signals out.
This kind of "Yo-Yo Hedge" can work at any currencies pair.
2, Buy (or sell) unequal lots of special currency pairs and buy unequal quantities of another kinds of currency pairs which usually move in the opposite direction. This seems a "Semi-Hedge" trading strategy. It is created based on “Correlation” between some particular currency pairs. So it is not suitable for every currencies pair.
Actually, this kind of hedge has another feature: earning SWAP! You earn interest daily on the held position which can yield up to 50% per year of your full account balance.
There are several pairs can do it. Such as EUR/USD Vs. USD /CHF, GBP/USD Vs. USD/CHF, AUD/USD Vs. NZD/USD, EUR/JPY Vs. CHF/JPY, GBP/JPY Vs. CHF/JPY.
Let's take the EUR/USD and the CHF/USD pairs.
These pairs are historically negatively correlative 93-98% of the . That is when one pair goes up the other goes down, and vice versa, up to 98% of the . In a high leverage account (as high as 400:1 or 500:1), you could earn 50% SWAP interest in a year. How? Let's say you have $5,000 in your account and a 10% risk margin set. If the net interest we receive is 1.25% annually, this 1.25% interest will be enlarged to 50% per annum, by the 400:1 leverage.
And, this return does not include the buy low/sell high profits.
But, if the base of this kind of hedge collapses, it means the “Correlation” does not exist any more, for example the “Correlation” drops under 50% or lower, there will be a disaster.
对冲：
在金融领域，“对冲”是一种用来减低另一种投资的风险的投资。对冲策略有助于减小暴露于意外的业务风险的可能性，同时继续保持该业务的获利性。
在外汇市场中，有两种类似“对冲”的策略：
1、同时买进和卖出同样数量的同一货币对。然后让它们自由运行。当其中一个单子上涨，对应的另一个单子就会下降。对盈利者提取利润后，我们等待亏损者反转。在一个上下反复震荡的市场里，这一招很管用。
例如：买进两手GBP/USD于2.0003，同时卖出两手GBP/USD于1.9997。当汇价升至2.0053时，我们结清买单并获利50点。现在，卖单跌去了50点，让我们等待汇率下跌，通常它会回荡，尤其是在震荡行情中。当汇率跌回至2.0037时，结清卖单，此一卖单将损失40点。亏惨了吧？不，别忘了在买单里我们已经提走了50点。总计，我们可以收获50-40=10点。更进一步，如果汇价继续下跌，比如说跌到2.0027，我们可以收获50-30=20点，等等。
一些人可能会怀疑……这种“对冲”听起来像是白白抵消了，什么也没得到，还付了双倍的点差？为什么多此一举？嗯，他们是对的，因为我们忘了说关键点：结单的时机。什么时候该结掉盈利单奠定获利基础，以及什么时候该结掉亏损单锁定总利润，那是要讲些诀窍的。有经验的交易员使用技术分析技巧去选择这个生死攸关的时机。不管你是否相信，那些老油条们说这种方法可以帮助他们筛掉虚假信号。
这种“震荡对冲”适用于任何货币对。
2、买入（或卖出）特殊数量的特定货币对，再买入特殊数量的另一种通常反向运动的货币对。这似乎该称为一种“准对冲”策略。它是基于某些特定的货币对之间的“相似性”原理所创造出来的。事实上，这种对冲有另外一个特性：可以挣利息！每天持仓积累下来的利息可以产生高达全部帐户余额50%的年利。
有几种货币对可以做此类对冲，比如：EUR/USD Vs. USD /CHF, GBP/USD Vs. USD/CHF, AUD/USD Vs. NZD/USD, EUR/JPY Vs. CHF/JPY, GBP/JPY Vs. CHF/JPY.
以EUR/USD 和 CHF/USD 为例：
这些货币对在历史上反向相似性为93~98%，即一对向上，另一对则向下，反之亦然，高达98%的时间都如此。在一个高杠杆的帐户里（高达 400:1 或 500:1），你可以挣到一年50%的利息。怎么挣？假设你帐号里有5000元，用10%的保证金去投资。如果收到的净年利率是1.25%，这1.25%的利息将被400倍的杠杆放大至50%每年。
而且，这个回报还没有包括低买高卖产生的高利润。
但是，一旦这种对冲的基础崩塌了，即“相似性”消失了，比如说相似性跌到了50%或者更低，那就是一场灾难。
