XR,
(Another blog. No need to reply.)
A large part of the wall street core infrastructure is built around the (regulated) exchanges and (unregulated) ECN’s, and includes the major trading houses’ trading systems — front and back ends, equities, fixed income, currency and commodities, including risk. Developers in these systems are the backbone of wall street.
I feel less than 50% of my company’s technology staff are application developers. Among them, less than 50% develop apps for real time trading. The rest of the developers support reporting, end-of-day risk, post-trading (like my team), GL, compliance, surveillance, price and other data feeds into trading systems and data feeds out of trading systems, maintain accounts and other reference data, ….
Trading system developers are employed by brokerage houses (aka securities firms), hedge funds, mutual funds, prop traders, exchanges, and many boutique firms(?) On the other hand, retail banking, consumer banking, corporate banking (they all taking deposits and giving loans) and the advisory business of investment banks don’t have infrastructure to trade securities. I don’t think they have access to the security exchanges.The IPO, M&A, privatization… investment bankers do need some access to trading systems, as they issue securities.
Overall, how many percent of the financial IT people are in the “backbone”? I guess not more than 10%.
