V********n 发帖数: 3061 | 1 Market making程序出错,造成NYSE约150个股票的价格异动,KCG据说损失了“
hundreds of million”....
Knight Capital (KCG) plunged 22% in massive turnover as it said a "
technology issue" at its market-making business affected trading of about
150 stocks. Volatile action had prompted a halt in trading for some NYSE
issues. The NYSE said it's reviewing trades in 148 stocks that occurred
between 9:30 a.m. and 10:15 a.m. ET. Reports said computer-based trading
appeared to cause huge volume and big price moves in certain stocks. |

a**i 发帖数: 608 | 4 Knight Capital [KCG 6.94 (---) ] - The trading firm is expected to
detail the impact of yesterday's technology glitch, which resulted in
irregular trading in a number of stocks. Knight said the software problem
that impacted order routing yesterday has resulted in a $440 million pre-tax
loss. Despite the hit to capital, Knight says it remains in compliance with
capital regulations.
一天 $440 M 的 LOSS, 这公司简直白痴啊,没有任何风险防范措施么?
小 TRADING FIRM 能经得起这么折腾么,离关门歇业不远了。

a**i 发帖数: 608 | 13 程序出问题不奇怪,
任何自动机都不能保证万无一失。
这件事神奇在人工 monitor 是干什么的呢,
它这也不是一个大单搞出的损失,
发现异常1分钟内关机就没这事了。
自动机只要在运行中,
每分每秒都是有人盯着的,
对各种突发情况也都是有预案的,
如地震,停电,断网,恐怖攻击等

KCG的market making engine出的問題是: buy at the offer, and sell at the bid
在昨天9:30 - 10:15之間, 以每分鐘約$10 mil的速度燒錢
