I have the same question as Scientist above, but, in the meantime maybe a little sympathy at least for the "1,418 employees ... in 21 locations around the world" if the company tanks and they're out of a job?
They're a market maker. They're not supposed to be taking proprietary positions. Marketmakers are meant to stand ready to execute orders for clients, and to take the opposite side of trades when there is an open interest (i.e., if the market wants to sell, market maker buys). The profit is supposed to come from the bid/ask (difference between what you're willing to pay for a stock and what you're willing to be paid to let go of a stock at the same point in time) and not from actual fluctuations in the price of the underlying.

The big argument about HFT is that it destroys the market makers business model but when something goes wrong they (HFTs) disappear and there is no one there to provide liquidity.
Theta States: If that doesnt work, try taking it out and blowing on it.
Regular expressions are not a good tool for anything where you can't afford to fail.
The only reason you're using a regular expression in the first place is because no one specified any actual data interchange format. So you're reduced to guessing what pattern is being used to generate the data you're receiving.
for most of the existing regexp parsers, it's possible for individual matches to take an extremely long time to complete for some patterns
always force the guy sending you data to specify exactly what you can possibly get, then write to that specification exactly
