I have been researching a wee bit on technology and impact on trading and I came across this rather interesting article about the rate of messages on market data. I quote:
Broader institutional participation, increased volatility, advancements in technology, remote market making, and regulatory changes are driving options quote volumes to higher and higher peaks. The six options exchanges in the U.S send their quote data to the Options Price Reporting Authority, which merges it into one feed and pushes it out to the market. During periods of heavy market activity, Opra sends out as many as 300,000 messages per second, far above what was seen just a few years ago.
To stay ahead of the curve, Opra has repeatedly advised the industry to boost its capacity to receive these market data messages. At the beginning of 2007, the required capacity level set by Opra was 359,000 messages per second. At the beginning of 2008, Opra had increased that level to 701,000 messages per second, and it is targeting 907,000 by the middle of 2008.
If you are interested in risk management (market, credit, operational and legal as well), do sign up to this site, very useful indeed.
All this to be taken with a grain of piquant salt!!!
