How much you want to bet? I didnt say i traded 100mm i said we floated 100 mm worth of orders we got filled on less than 1% on a daily basis all on non news stocks, it was systems based trading, but we needed buying power to FLOAT THE ORDERS. Didnt we? or am i making that up too?
What do you have to bet? Bankrupt and a 450 FICO isn't super hard-on inducing on my end.
So you're not trading a neutral book of $100MM... your flow is $100MM and you're FOK on <$1MM.
It's meaningless. On the buy-side you've got risk-limits, which in my line are gamma(or theta) per underlying and global. At Millennium my global limit on theta (easier to asplain) was $350K. Yuri was the risk-manager on the equity vol. He preferred using a dollar-figure/gamma due to GBM.
Millennium is a pretty big outfit. I hear they're over $30B now.
