头寸（position）
头寸的定义
1、头寸（position）也称为“头衬”就是款项的意思，是金融界及商业界的流行用语。如果银行在当日的全部收付款中收入大于支出款项，就称为“多头寸”，如果付出款项大于收入款项，就称为“缺头寸”。对预计这一类头寸的多与少的行为称为"轧头寸"。到处想方设法调进款项的行为称为“调头寸”。如果暂时未用的款项大于需用量时称为“头寸松”，如果资金需求量大于闲置量时就称为“头寸紧”。
2、头寸是金融行业常用到的一个词，在金融、证券、股票、期货交易中经常用到。
比如在期货交易中建仓时,买入期货合约后所持有的头寸叫多头头寸,简称多头;卖出期货合约后所持有的头寸叫空头头寸,简称空头。商品未平仓多头合约与未平仓空头合约之间的差额就叫做净头寸。只是在期货交易中有这种做法，在现货交易中还没有这种做法。
在外币交易中，“ 建立头寸”是开盘的意思。开盘也叫敞口，就是买进一种货币，同时卖出另一种货币的行为。开盘之后，长了(多头)一种货币，短了(空头)另一种货币。选择适当的汇率水平以及时机建立头寸是盈利的前提。如果入市时机较好，获利的机会就大；相反，如果入市的时机不当，就容易发生亏损。净头寸就是指开盘后获取的一种货币与另一种货币之间的交易差额。
另外在金融同业中还有扎平头寸、头寸拆借等说法。
头寸日有分很多种的：第一头寸日(期货交割过程的第一日)等等，多数就是指对款项动用的当日。
3. 头寸有两种含义
(1).[money market]∶中国旧时指银行钱庄等所拥有的款项。收多付少叫头寸多,收少付多叫头寸缺,结算收付差额叫轧(ga)头寸,借款弥补差额叫拆头寸
(2).[cash]∶指市场上货币流通数量,即银根。如银根松说头寸松,银根紧也说头寸紧通常所说的是指第二种,即现金的量.

就是啊！这不是流氓该进的地方！
请问 keep positon在金融界里怎么翻译呀？
应该是 keep position吧？就是留仓
Dealer must hold a portfolio of the securities they trade, which known as position
That's right, it it just a simple verbal translation of word "position". As the same as the the word used in English language, it has multiple meanings rather than a single financial explanation usage.

持仓
In financial trading, a position is a binding commitment to buy or sell a given amount of financial instruments, such as securities, currencies or commodities, for a given price.
The term "position" is also used in the context of finance for the amount of securities or commodities held by a person, firm, or institution, and for the ownership status of a person's or institution's investments.
[Long position] -When a trader buys an option contract that he has not already written (i.e. sold), he is said to be opening a long position. -When a trader sells an option contract that he already owns, he is said to be closing a long position. -When a trader is 'long', he/she wins when the price increases, and loses when the price decreases.
[Short position] -When a trader writes (i.e. sells) an option contract that he does not already own, he is said to be opening a short position. -When a trader buys an option contract that he has written (i.e. sold), he is said to be closing a short position. -When a trader is 'short', he/she wins when the price decreases, and loses when the price increases.
The long and the short of it is that: buyers are referred to as the long; and sellers are referred to as the short.
[Net position] -Net position is the difference between total open long (receivable) and open short (payable) positions in a given assets (security, foreign exchange currency, commodity, etc...) held by an individual. This also refers the amount of assets held by a person, firm, or financial institution as well as the ownership status of a person's or institution's investments.
我覺得如果覺得別人說的不好的話，可否指正一下，以免後面的新手混淆，來點建設性的建議，批評並不會帶�%8

新解：手头上的钱用尺子来量有多少寸——银行的钱太多了，数起来麻烦，用尺子量比较快～～ 所以简称‘头寸’～～
错了，头寸是余额的意思。
