b*******g 发帖数: 1309 | 1 你这个应该叫transmission efficiency,QQQ,从形成离子进入Q1开始算,到Q3,效率
超过90%,好像在95%以上,所以要提高LOD必须在ionization source 跟Q0上下功夫。
举个例子AB Sciex 的6500跟5500 的区别就是source enhance 2倍LOD,Q0(Qjet)
enhance 2倍2LOD,共计4倍LOD
QTOF 的ion transmission主要是损失在 flight 过程中,另外TOF的pulse frequency
并不慢,大部分仪器都在 20kHz 左右,就是0.05ms一次。
速度慢在仪器跟电脑之间的传输,没想到吧,每个TOF的spectrum在被digitization过
后从instrument到电脑需要的时间在ms ,这段时间TOF只能idle等digitizer
clearance
所以QTOF效率取决于duty cycle time跟飞行过程中的离子损失。QQQ现在的duty cycle
一
般可以到2-5ms per MRM,但是QTOF最快能到10ms,一般只能到50ms。意味着同样的时... 阅读全帖 |

List of Inverse ETFs (Short ETFs / Bear ETFs)
After some research I thought recently that I may want to place some bearish
bets in my OptionsHouse IRA. Inverse ETFs (exchange traded funds) are a
good way to do that so I wanted to make sure I had a list of short ETFs at

c**y 发帖数: 419 | 7 好久没发新的美股文章了, 因为我的博客不是每日股市报道, 而是方法研究,方法不是
每天都有新的. 所以你只要放上我的跟踪止损指标自己看各个市场就行了. 比如下图是
sp500 mini futures (用FXCM.co.uk网站上的免费MT4软件看) 2011年9月到2012年1月5
日的4小时K线图, 和2%的跟踪止损(附图).可见跟踪止损是多么有效.
中国的上证指数就更不用说了,一直维持在2%的跟踪止损下面,根本没行情,不用去看.
2011年市场之所以波动剧烈,不谈欧债危机这些news层面上的东西, 从技术分析层面上
说, 则是以sp500指数(用spy,rsp都可以)为代表的市场,经历了2009-2010年,又回到了
2008年暴跌前的1400多点. 所以是个经典的double top, 当年在2008年顶上被套住的人
,这么快就迎来了解套, 能不逃么.
2012年美股关注的热点:
1)指数基金: spy(标准普尔500,市场的总体方向), qqq(纳斯达克的科技股依然是增长
的动力), dia(道琼斯指数含有大量的抗跌的公司,比如IBM,麦当劳等等). 2011年下半

r***l 发帖数: 9084 | 10 ”高回报高风险“这个我不同意。我的本质意思是,小股票小药股,是高风险
eventually负回报或者输光. 如果明天一个药股要fda决定,今天全仓买,赌对了就收
手不干了。我对这种操作没意见,毕竟是50%几率,这个的确是高风险高回报。 但像大
部分人操作的方式,反反复复折腾,这个就是极大增加自己wipe out的几率.
至于说我提倡的炒蓝筹,炒spy/qqq, 其实好处很多。首先你可以大仓位上,没啥可担
心的,spy涨个1刀,你赚的不见得去搞小股票少。都说zijing mm厉害,可人家就是交
易的qqq option. 我相信也有保护。option再多学一些,像我说的,如果是炒股的料,
操作spy/qqq不会耽误成百万富翁的。 话痨mm交易也是iwm的option spread, 要就图个
beat通胀,真不用费这劲。股版前辈大傻蛋早就英明指出了,炒股是炒大盘和单边做多
,我觉的这10几个字才是真谛。 |

如果你炒股是靠蒙的,买SPY(3倍了), QQQ(4倍了)这种index fund比这些垃圾股强
百倍。

主要风险
1. 中国宏观经济,人民币贬值
2. 旧游戏衰退过快,新游戏失败。 |
