怎樣對多頭倉位平倉

關閉一個多頭倉位取決您的經紀商是否受美國交易法規的監管。

在2008年金融危機之後,美國國會通過的多德-弗蘭克法案導致了嚴重的外匯交易法規的變化。其中一個就是無對沖規則條例。在引入這個規則之前，外匯交易員可以可以通過相同貨幣對的空頭對已存在的多頭進行對沖。

例如，交易員在1.35的價格對歐元/美元進行了多頭操作。交易員之後發現該貨幣對有在1.38封頂的迹象。因為價格仍然可能上漲，交易員不想放棄持有的多頭倉位，但是他想使自己免於一個臨時下降調整或者市場真正反轉的損失。因此，他在1.38對歐元/美元貨幣對進行了空頭。這個交易員此時就同時持有多頭和空頭倉位。一個方向的損失將會被相反方向的操作抵消。理想情況下，進一步的市場活動將會揭示長期市場趨勢並能關閉其中一個倉位並獲利，留下另一個倉位，希望在未來長期趨勢中獲得更大的利潤。

監管制度的改革禁止了對沖操作。現在在美國監管制度下，如果一個交易員存在多頭訂單，他想要進行空頭操作，那麼他的空單操作只能關閉他的多頭訂單。在美國監管規定下的交易員，對持有的多頭倉位的平倉方法是賣出該貨幣對。

然而，那些運用經紀商公司不受美國監管制度限制的交易員必須通過選取多倉位置並發佈指令來進行平倉。如果發起一個空頭訂單，那麼就建立了一個如上面描述的多頭和空頭的對沖。

How do I close a long position in forex?

Closing a long position in forex trading depends on whether you are using a broker operating under U.S. trading regulations.

In the aftermath of the 2008 financial crisis, the Dodd-Frank act passed by the U.S. Congress resulted in severe changes in forex trading regulations. One of those changes was a no-hedging rule. Prior to the introduction of the no-hedging rule, forex traders could hedge existing long positions by initiating short positions in the same currency pair.

For example, assume a trader establishes a long position in EUR/USD at 1.35. The trader then sees signs of the market possibly topping out at the 1.38 level. The trader doesn't wish to abandon his existing long position, since the price may still go higher, but he wants to protect himself against a temporary downside correction or actual market reversal. To do so, he initiates a short position in EUR/USD at 1.38. The trader now holds both long and short positions in the market. Losses in one position will be offset by profits in the opposite position. Ideally, further market action will reveal the long-term market direction and one of the positions can be closed out, potentially at a profit, leaving the remaining position in place, hopefully to amass greater profits from the market's long-term trend.

Regulatory changes eliminated the use of hedging. Now, under U.S. regulations, if a trader places a sell order in a market where he has a long position, the sell order will only close out the existing long position. For traders operating under U.S. regulations, the way to close a long position is to enter a sell order for the currency pair he is long.

However, traders using a brokerage firm that is not under the operational control of the U.S. regulatory authorities must close existing long positions by selecting the long positions on their trading platform and sending an order to close the position. If they instead initiate sell orders, a hedge of both long and short positions will be created, as described above.
