for this trade。
假设你的交易账户有50000元。你想买XYZ 股票,当前市价为20元。你的赢利目标是26 元,止损设在18元。那么你可以买多少股XYZ呢?50000元的2%是1000元,也就是你可以接受的最大风险。在20元买进,并在18元设置止损,那么你的每股风险为2元。用最大可接受风险除以每股风险,就得到你可以购买的股数。1000元除以2元,结果为500股。这就是理论上的最大股数。实际上,那个数目应该更低一些,因为你必须支付佣金和准备应付滑点亏损的影响,所以这些费用加起来都不得超过2%的限制。故是400 股,而不是500 股,就是你的交易上限。
I’ve noticed a curious difference in how people react to the 2% Rule。 Poor beginners think this number is too low。 Someone asked me at a recent conference whether the 2% Rule could be increased for small accounts。 I answered that when he goes bungee jumping; it doesn’t pay to extend the cord。
我已经注意到人们对2%原则的反应有非常奇怪的差别。可怜的新手认为这个数字太小。在最近一次研讨会上,有人问我对于小账户来说,2%原则是不是可以大一点。我回答说,当他去蹦极的时候,延长绳子没有什么好处。
Professionals; on the other hand; often say 2% is too high and they try to risk less。 A very successful hedge fund manager recently told me that his project for the next six months was to increase his trading size。 He never risked more than 0。5% of equity on a trade … and was going to teach himself to risk 1%! Good traders tend to stay well below the 2% limit。 Whenever amateurs and professionals are on the opposite sides of an argument; you know which side to choose。 Try to risk less than 2% … it is simply the maximum level。
专业交易者则相反,他们常说2%太高了,他们努力使风险更低一些。一位非常成功的对冲基金经理最近告诉我,他计划在接下来的六个月中增加他的仓位。他从未在单笔交易中使风险超过净资金的0。5%——而现在自己努力把风险比例上升到1%。优秀的交易者安于2%限制之下。无论何时只要业余选手和专业交易者的意见相反,你心里应该明白谁是对的。尽量使风险低于2%——这就是最高风险。
Whenever you look at a potential trade; check whether a logical stop on a round lot or a single contract would keep you on the right side of the 2% Rule。 If it would put more money at risk; pass that trade。
无论何时进行交易,都要检查所有或单份合约的逻辑止损是否满足2%原则。如果哪次交易要求有更高的风险,那么就放弃交易。
Measure your account equity on the first of each month。 If you start the month with 100;000 in your account; the 2% Rule allows you to risk a maximum of 2;000 per trade。 If you have a good month and your equity rises to 105;000; then your 2% limit for the next month is … how much? Quick! Remember; a good trader can count! If you have 105;000 in your account; the 2% Rule allows you to risk 2;100 and trade a slightly bigger size。 If; on the other hand; you have a bad month and your equity falls to 95;000; the 2% Rule sets your maximum permitted risk at 1;900 per trade for the following month。 The 2% Rule lets you expand when you are ahead and forces you to pull in your horns when you do poorly; it links your trading size to your performance。 What if you have several trading accounts; for example; one for stocks and another for futures? In that case; apply the 2% Rule to each account separately。
在每月初,都要检查你的账户净资金。如果起始月时你的账户中有100000元,那么2%原则允许你每次交易冒2000元的风险。如果上月赢利,净资金上升到105000元,那么在下个月你的2%限制将是多少钱?快点回答,记住,要做一名优秀的交易者,算术能力一定要好!如果你的账户中有105000元,2%原则将允许你冒2100元的风险,可以交易稍多一点的金额。反之,如果你上月亏损,净资金降到95000 元,2%原则将限制你在下月交易中所冒风险的金额为1900元。当你表现优异时,2%原则允许你扩大自己的交易金额,而当你表现欠佳时,它会强制你减少交易金额,这使得你的交易金额与自己的表现联系在一起。如果你有好几个交易账户时该怎么做呢?比如,你用一个账户做股票,另一个账户做期货。在那种情况下,要在每个账户中分别使用2%原则。

Imagine two traders; Mr。 Hare and Mr。 Turtle; both with 50;000 accounts; who are looking at two futures markets … S&P 500 and corn。 The agile Mr。 Hare notices that the average daily range in the S&P is about 5 points; worth 250 each。 The daily range in corn is about 5 cents; worth 50 each。 He quickly figures that if he catches just a half of a day’s range; he’ll make over 500 per contract in the S&P; whereas the same level of skill will bring him just a little over 100 in corn。 Mr。 Hare calls his broker and buys two contracts of the S&P。
想象一下有两个交易者,兔子先生和乌龟先生,各有一个50000元的账户,他们正在观察两个期货市场——标准普尔和玉米。机敏的兔子先生注意到标准普尔的平均日价格区间约5 点,每份合约的价格为250元。玉米的平均日价格区间为5分,每份合约为50元。他很快就得出结论。如果他只能抓住日价格区间的一半,那么在标准普尔每份合约可以赚500元,而使用同样水平的技巧,在玉米中只能赚100元多一点。兔子先生打电话给他的经纪人,要求买两份标准普尔合约。
The cautious Mr。 Turtle has a different arithmetic。 He begins by setting the maximum risk in his account at 2% or 1;000。 Trading the S&P; moving over 1;000 a day with such a small account; is like grabbing a very large tiger by a very short tail。 If; on the other hand; he trades corn; he’ll have a lot more staying power。 That tiger is smaller and has a longer tail; which he can wrap around his wrist。 Mr。 Turtle buys a contract of corn。 Who is more likely to win in the long run; Mr。 Hare or Mr。 Turtle?
但谨慎的乌龟先生却有着不同的算法。首先,他使用2%原则计算出自己账户的最大可承受风险资金1000元。在标准普尔中,在这样的小账户,一天只动用1000元,就像去抓一只个头非常大,但尾巴非常短的老虎一样。另一方面,如果他交易玉米,他就有更大的生存能力。那只老虎要小一些,而且有一条可以缠在腰上的长尾巴。乌龟先生买了一份玉米的合约。那么在兔子先生和乌龟先生中,谁最终将取得胜利呢?
To find out which futures markets you may or may not trade; measure your equity against the recent level of market noise。 Begin by calculating 2% of your account。 Measure the level of noise with the SafeZone indicator; calculate its 22…day EMA; and translate that into dollars。 Do not trade any market whose average noise level is more than 1% of your equity。 If you follow this rule; you’ll trade relatively sedate markets where you can safely place your stops。 Why 1% and not 2%? Because your 2% stop will have to be more than the average noise level away from the market。
在期货市场中选择期货商品时,比较一下你的资金和近期的市场波动水平。首先计算出你的账户资金的2%。使用安全区域指标度量波动水平,计算出其22日均线,并将结果化为金额。如果平均波动水平高于你账户资金的1%,就不要交易那只期货。如果你遵守这条原则,你所选择的市场相对来说是比较稳定的,可以比较安全地设置止损。为什么是1%,而不早2%呢?因为在市场中,你的2%止损必须大于平均波动水平。
The first column in the spreadsheet in Table 7。1 lists the market; the second the value of one contract; the third the current SafeZone indicator; and the fourth multiplies SafeZone by two。 The fifth column lists 2% of the account value; in this case 30;000。 The last column pares the value of SafeZone multiplied by two to 2% of the account。 If the latter is greater than the former; that market is OK to trade。
表7。1的第一列是期货市场,第二列是每份合约的价格,第三列是当前的安全区域,第四列是用安全区域指标乘以2所得结果。第五列是账户资金的2% ,此处账户资金为30000元。最后一列比较两倍的安全区域指标与账户资金2%。如果后者大于前者,那个市场就适合交易
