mitbbs2020 (bbc) 于 (Sun Jul 25 16:27:03 2010, 美东) 提到:
trader1688上也有人提过pair trading，并有人表示怀疑。
这个idea是80年代摩根斯坦利的人提出来的idea，然后finance行业的人又比较liquid
，跳几次槽，这个idea就逐渐流行起来了。
基本的想法是，high correlated的two stocks，spread比较稳定，假如某个时刻出现
了比较背离average的情况，基本上是可以认为一个overprice，一个underprice，然
后long那个underprice的，short overprice的symbol，以期spread恢复至正常。
这里overprice和underprice都是相对而言，加入两个symbol都涨了，期望的是long那
个涨的比short的那个幅度更大，spread还是可以按照期望发展，反之亦然。
我测试过NASDAQ的2700多个symbol的测试，算Spearman |

发帖数: 1736 | 4 我正在研究你的stragety,能确认一下是否可以盘后交易吗? 在那个brokage, 怎么交易
? 我怎么看到盘后不能交易option啊?
此外,那个brokage可以做weekly option? fidelity and etrade 好象不行啊.
谢谢. |

BJ来的高
你一个call+put要3000块了，现在就是盘后跌到250也才在put上找回来，想赚不容易啊 |

发帖数: 31 | 7 I submitted my EB1A 4 months ago. My H1 visa will expire this August. I
found many people said they wait more than 8 months. It is scary. Is there
anyone here who is very kind to tell me the regular procedure to push the
office to review the case? I tried to find related information here, but it
seems very difficult. What is the "three steps stragety"? thank you so much
for your time and help.Still wonder if it is worth to spend so much time in

发帖数: 280 | 8 我的个案可能不具有代表性，我没有所谓的专业技术，文科出身，还不是英文专业。还是跟大家分享一下过程。
去年4月底离开原来的工作，彻底过来团聚。然后一直休息，美其名曰take a break. 晃晃荡荡，直到8月。觉得自己应该找个工作了，就去见了一个蓝里人力资源什么机构的Case Manager。 第一次去仅是预约而已。一周后 才见到真人。 我去看他的目的，是想请他帮忙参考下什么工作会比较适合我，因为我没能在这边的各种招聘广告上看到跟我以前的工作类似的职位（估计在多伦多那边的所谓跨国大公司能找到）。我可以改行，但是做什么呢？想听听他的意见。结果，那个家伙跟我说：我也不知道，我只能推荐你去一个培训，他们会教你如何找到想要的工作。当即电话联系另外一个培训机构，3分钟就把我打发了。
9月份，三周的培训课，每天9-3，一下子觉得自己忙起来了。闲散几个月了，有些不适应了。培训课的名称是“Stragety Job Searching” ，如何写简历Cover Letter， 如何发现潜在的职位，如果冒昧的联系可能的雇主， 如何面试，如何……说不上有多大的用处，因为教的东西我都没用过。课上完成的文件，每 |

soccer: too much crash during the game,
Football: concussion.
Swimming help building both endurance and body.
Tennis is a taste of speed and stragety
Road bike is safer but also good habit for general excercise
Wrestling is for powerful self defense when it is necessary, you can take
down a guy twice of your size in a split second. How does that sound like

发帖数: 606 | 14 i wrote a whole paragraph then accidentally eraised them all. . . will try
to be brief here:
if it was 30-40bb, then you made a huge mistake by calling with K7s. just a
little bit of patience will get you there. i would wait for the top 10%
hands to call, that would give you more than 60% chance against a random
hand.
SAGE only come into play when one of you are short stacked (less than 10bb).
it is basically an unexploiable jam-fold stragety when you don't want to
give your oppo any edge. i |

发帖数: 15860 | 15 nah, or you should think in this way, live (especially 1/2NL) and online are
like two different stages in a tournament, you need to use different
strageties accordingly (hands/hr, stack, donk level, etc.). your core game
might be the same, but you need to balance your range too.
even online, calling a 3.5x with 5s6s in a 4-way pot with position is
totally fine. yes, most of time, you're behind (guess what? only AA is
absolutely not, lol), but why you're playing this hand? because:

发帖数: 9164 | 16 I was not involved with this hand. but I am very impressed with the play
from a good reg.
It was a 2-5 NL no cap game. Lots of time the stack can go crazily deep.
This hand involved two good regs that I was both quite familiar with.
Reg 1 is from NJ, he used to play at AC a lot. Quite solid player.
Back then ,he already started to play Bellagio 10-20 NL. We used to talk
some poker stragety together. He had 10k at the table. Reg 1 had a bad day
so far and lost a few hundred buck... 阅读全帖 |

Q*******e
发帖数: 939 | 17 Read some previous posts,
a lot touch LB algorithms.
How about listing some LB strageties
we have met or implemented?
Here is a list of questions of mine:
1) How to evaluate load inbalance? the metric: such as
users number in a cell, interference factor, tasks,
CPU usage, click-rate.
2) Is the algorithm centric or distributed?
3) What's the network entity:Cell, Switch, Computer, Multiprocessors
A lot of others :) |

发帖数: 1632 | 19 我来说个简化过的例子吧，来解释一下其中的一条：历史依赖性。细胞培养在 serum-
free 的 medium 里，然后给一个 0.3% 的 serum step，发现细胞不会 proliferate；
如果先给一个 20%x5hr 的 serum shock，再给 0.3% 的 serum step，细胞就会
proliferate。也就是说，0.3% 的 serum level 是否会促使 proliferation，取决于
之前有没有过一个 serum shock。[1]
我的问题：如何寻找到某种提供 serum 的 stragety，可以使得细胞 proliferate，同
时使得提供给细胞的 serum 最少。也就是说，寻找某种 temporal serum level
profile，使得细胞 proliferate，同时使得这个 profile 下面的面积最小。这个问题
的生物学上意义可想而知了。目前大家主要研究的是一个信号的 on 或者 off，有或无
。而 in vivo 大部分信号都是小幅波动的，最常见的波动周期是 24hr。根据我现在的
模拟结果，和 consta |

发帖数: 80 | 20 yes,it's a block code
the parity check matrix is very sparse,or said differently, low density.
Gallegar discovered this in 60s and people rediscover this code
in late 90s which shows performance(w/ 10^7 block length)
very close to shannan capacity.
This code and another popular codes--turbo codes use similiar
iterative decoding stragety. A new tool--factor graph
(or normal graph in Forney's vocabulary)
is also formulated to anaylize the behavior of those codes.

发帖数: 607 | 26 可能更接近Marketing方面的，无奈找不到合适的版面，发在这里，请教各位大牛们吧。
我们公司的communication stragety有时候会做一些split test，有的比较简单，就是
email template A VS B那种，
有的复杂一些，比如我们给贷款欠费的人打电话，欠费３０天的只发mail，９０天的打
一个电话，发一封信，１２０天的打三个电话，发一封信，需要用split test来测试，
比如测试欠费９０天的人，发不发那封信其实差别是一样的，到欠费１２０天，是否发
mail有区别，之类的，当然实际情况更复杂一些。我想找一些关于设计这样的test的
training，或者书，coursea上我也搜了，可能关键词用的不对，也找不到，麻烦各位
大牛们给推荐下把，多谢！ |

1.75 heavy RE, but it isn't easy to dig due to poor baic facility around

Currently, MCP and REE are more famous and they can attract more traders'
