We use computer-based simulations of stock market as a background environment for experimental tests of the integration of an order-driven trading system into a dealedquote-driven market. Experimental subjects traded using a traditional dealer quote screen (such as Nasdaq in the U.S. or the London Stock Exchange's SEAQ), to which was added a public limit order facility. Data captured on subject...

“Those who cannot remember the past are condemned to repeat it” [1]. The famous quote from Hispanic American philosopher George Santayana reminds us of the critical importance of constantly reflecting on the most important lessons garnered from both our own personal experiences and those of our peers.

A resource-efficient approach to making inferences about the distributional properties of the failure times in a competing risks setting is presented. Efficiency is gained by observing recurrences of the compet- ing risks over a random monitoring period. The resulting model is called the recurrent competing risks model (RCRM) and is coupled with two repair strategies whenever the system fails. ...

This column examines and evaluates several techniques for developing multi-threaded servers. The server we’re examining mediates access to a stock quote database. Desktop client applications operated by investment brokers interact with our server to query stock prices. As with our previous columns, we’ll compare several ways to program multi-threaded quote servers using C, C++ wrappers, and CORBA.
