《程序员、交易员到亿万富豪》－他推动了美国证券交易的电子化变革

有趣的数字，Excel格式，IB从2008年以来每个月的账户数，以及期权、期货及股票的月交易量：

其中 最新的2010年8月统计：
Options Contracts 18 million
Futures Contracts 6.6 million
Stock Shares 4,510 million
客户资产：173亿美元

• 149 thousand customer accounts, 19% higher than prior year.
• 348 thousand Daily Average Revenue Trades (DARTs), 2% higher than prior year and 5% lower than prior month.
• Ending customer equity of $17.3 billion, 37% higher than prior year and 1% lower than prior month.
• Ending customer credit balances of $12.0 billion and customer margin loan balances of $4.6 billion.
• 536 annualized average cleared DARTs per customer account.

 

我估计是这个数字不好统计。个人换外汇也算在里面，没法按笔数算。可能的话只能是佣金收入，多少美元来计。
