发帖数: 6389 | 3 options价格波动很大。1块钱买的call，也许第二天上午涨到2块，下午又跌倒5毛去了。
当股票有了浮利，为了防止价格低过成本，可以设一个stop order。但是这对options
是行不通的。原因是options的成交量小，有的一天才几百个contract。经常last
price不在当前bid/ask范围之间。如果用stop order，当last price小于某个价位，立
刻按bid价格卖出，可能卖出价和last price差了10%以上。要是有几百个contract，损
失就可想而知了。
一个解决方案是用程序监控options的bid/ask价位，一旦bid低于某个价位，立刻放一
个比bid稍高一点的limit order卖掉，而不用last price来监控。买的时候也是，盯着
ask而不是last。这样可以把成交价位控制的比较精确。
对这个程序感兴趣的，站内私信联系。:) |

发帖数: 89 | 4 一般的好像只有一条 Ask / Bid的信息
比如:
Ask 10 / 5
Bid 11 / 5
有没有什么软件可以看实时的所有的Ask / Bid的信息的？
比如
Ask 9 / 10
Ask 10 / 5
Bid 11 / 5
Bid 12 / 34
谢谢！！ |

(1) I think my "beautiful bid" means: bid a slam with good trumps.
(2) Whatever your beatiful bid means, someone once told me that if partner
makes a slam try and I have good trumps to accept.
Opening lead: c Q
How do you plan the play after all of this beautiful bidding? |

发帖数: 244 | 6 It's not good to bid dbl in the first round since you
don't know if opps hold strong hand or not. If you bid
dbl in the first round, with moderate hand, Opps may
bid game just because of your kindly "dbl". The situation
changes a lot in the second round after the bidding.
I prefer bidding dbl in the second round. |

发帖数: 97 | 7 what system you were using in that 1C, 16 points opening? does it make sense
to bid like that? I prefer an honest bidding and always a precise describe of
your hand at first bid. I would bid 1NT while using sayc.
I had played with some excellent players, any time I bid not honest, I got
lessons.

opp pass during the bidding. I open 2c, pd 3c, then 3D-4C. I bid 4N asking for
aces.
if pd bid 5h, life is easy. I continue to 5n to see if he has any k. Actually
even if he doesnt have, i might still try 7n, coz there are chances we can
have a squeeze or finesse.
The problem is that if pd bids 5d, showing only 1 ace. should i bid 6d or
not then? if pd have h ace, i think should, if pd have club ace, then i have
to stop. bu |

发帖数: 623 | 9 You raised a good point. Under the normal treatment of Michaels, 4C is to
play. Just like, after 1S-2S-P-? 2N is to pick the minor. But adopting the
philosophy of multi is much better an idea, as then you can bid pass or
correct. This would be particularly nice if you have a C fit as then one bid
you will suggest a sac.
So in this hand you can bid 4D to show both your D support and huge C by a
voluntary bid. After that you've fully described your hand and don't want to
take another bid.

发帖数: 2449 | 10 Open 1NT is a good though.
But rebidding 1NT after 1s? not good ba
Why the biggest evil is rebidding 2D?
first of all, open 1D is 4 card, bidding a suit show 5 cards and show no NT
interests is not that bad ba.
IF you PD have some streng, he could bid 2S after 2D.
then you should have a 4S. or if he has 4H, he could bid 2H...
even he has C suite other than S and around 10 points, he could bid 2NT.
so what do you lost for 2D?

you use 2/1, so you go with 1NT.
Obviously, if P bid 2H, you will be very happy to bid 4H.
Now, if your P bid 2c/2d what is your guys opion?
2H?
Or if your P bid 2s, will you bid 3H, or pass? |

发帖数: 2449 | 12 Agree, it is forcing to 2nt.
If P bid 2nt, I will bid 3c.
If P bid 3c 3s 3nt 4s, I will pass.
If P bid 3h or 3d to invite, I will bid 4s. |

and all pass.
His hand is

AJT872

AKJ6
He claim,
P I bid 4C, already shows extra, for your 4s, I have no interests.
So if you wanna bid slam, bid directly.
Now, how to evalue the hand?
Who should responsible
P' 5c
or my pass 5c.

1D (pass) 1H (1S),
Dbl(pass) 2D (pass),
2H (pass) ?
first of all, if the partner has this hand:
S xxxx H AQx D KQxxx C A,
bidding 2H might be too "subtle", you are holding all the cards and choose
not to tell your partner and let your partner to guess out of the dark. The
question is
1."Do you really have to bid 2H with such a strong hand and matched suits?"
2. Is there any other better bid from the one who bid 2H?
3. shouldn't u(the one bid 2H) start dominate the biding |

发帖数: 2804 | 15 It should not be a cuebid. If you have diamond fit, you should have bid 2S (
that IS a cuebid) earlier, instead of double. If you have general value but
not able to double 4H, you can bid 4NT here.
If bidding is below 3NT, you might bid 3S (as cuebid) to search for 3NT. But
here bidding is at 4-level, so I cannot think of a need for cuebid. |

发帖数: 642 | 16 Without special agreement, 4H and 4NT may be explained differently.
If 4H shows limit raise by agreement, then 3H doesn't have to set up trump.
But apparently, this 4H consumes room for slam bidding. But at least this
design uses 4H bid, otherwise there is no meaningful 4H bid with this
sequence.
4NT RKC, without explicit trump, should assume the last bid suit as trump,
in this case it is D. The same principle is for 4C cue bid, which is for D,
rather than H. It seems confusing to treat 4C and 4... 阅读全帖 |

发帖数: 20570 | 17 You can just cubbid 4C and hope to hear 4D from partner.
After Partner's 4D, you should just RKC with 4S. After 4NT, which shows 1 KC
, a normal treatment is to bid 5S to ask for side suit kings. If you happen
to have some better gadgets here, you should bid 5NT to show SQ and all KC
and HQ. 5NT also denies DQ (because you have skipped 5D). Later, partner can
bid 6C to show CK, 6D to show DQ, blabla...
If partner just bids 4H over 4C, you can also try 4S as RKC probably.

发帖数: 48 | 19 一般来说在
http://www.biddingfortravel.com/
找到最近的bidding价格
你都可以在priceline上bid到
我的做法是先在hotwire.com
查一下价格
然后再到priceline上bid
曾经在LAX bid过$10一天的车
现在不可能了
估计是租车公司采用了不同的策论
我今天bid的是Feb14-20 六天 Midsize
$15 rejected
$16 accepted Avis
估计Compact $14 可能会被接受
低于$14 不太可能
我前几天已经试过多次
如果你仅仅是weekend (Fri-Mon)要车
可以在Local租车
最近Hertz和Enterprise 都有50% off
还是比较划算的
最后给一个Avis的AWD C031529
这个可以给出比较好的价格
Hertz我一般都是直接用AAA的discount
比Costoc Sam Walmart的都要好
然后再找一些Coupon
有时候也可以找到不错的Deal |

“解决方法之一就是把
brooklyn区复选上，出价稍高一点比如$113，再次bid。因为该区实际上无4星级酒店，
实际上还是在bid central park区的4星级酒家。依次类推，如果有n个区块，每个区块
里都没有4星级酒店，那么bid 某个特定区域4星级酒店的次数，理论上是2的n次方。”
因为每个没有4星级酒店的区块都可以有选和不选两种可能，n个这样的区块就一共可以
有2的n次方种可能，而这2的n次方种可能其实对bid某个区的4星级酒家来说，没有任何
区别，就等于给了你2的n次方个出价而不改时间/地区的机会。
你这么说也没错，不过我原文转到说二星级去了，呵呵，转弯让人搞不懂了 |

发帖数: 344 | 21 1, there will be a record of the previous request that was rejected, but you
can start a new request with the same conditions after 24hrs (the new
request will be assigned a new request number)
2. not sure what you mean by reject / abandon a bid...all bids are final if
accepted. Unless you place the bid in error, like you picked the wrong dates
/ location than what you intended, you can call the customer service and
they might allow you to use the funds on a new bid.
The bid is not an open reque |

发帖数: 3693 | 22 如果在大城市而且bid的星位比较高，就可以用所谓的free bid zones，比如说，你想
bid Chicao Downtown的一个四星级酒店，第一次不成功后可以加一个确定没有四星以
上酒店的附近区域，然后加点钱继续bid，一直到用完这些free bid zones为止。 |

发帖数: 906 | 23 我上周bid了一个当天晚上的旅馆,在不算太大的大城市
rebid到没怎么用,因为只有2个zone,一个有3*,一个没3*,
我bid 3*的,所以每次算有一个rebid机会
因为有4个人要2个房间,每bid一次就只用同一个人名字
这样bid了8次,还是不行
最后把first/last name换了再来重复,才bid到,前后一共13次
换email换card还是不够的,即使我每次用不同的virtual cc&email,
只要入住客人名字有重复还是不行的
first/last name搞错了,一般去hotel跟人解释一下都没啥问题的 |

发帖数: 1038 | 24 提前两个星期开始BID一大城市DOWNTOWN的四星以上HOTEL.从$50开始,每次BID加$10,最
后到$105拿下,该地区三星在EXPEDIA上高于$110.
BID下的HOTEL的星级在AAA TOURBOOK只是三星,在EXPEDIA上是三星半,感觉PRICELINE的
星级不太可靠.
不知是BID的时间不对,象这种HOT的地方是不是早些BID更好呢?总之经验不足,没有拿到
很好的DEAL. |
