Dealing systems are on-line computers that link the contributing banks around the world on a one-on-one basis. The performance of dealing systems is characterized by speed, reliability, and safety. Accessing a bank through a dealing system is much faster than making a phone call. Dealing systems are continuously being improved in order to offer maximum support to the dealer’s main function: trading. The software is very reliable in picking up the big figure of the exchange rates and the standard value dates. In addition, it is extremely precise and fast in contacting other parties, switching among conversations, and accessing the database. The trader is in continuous visual contact with the information exchanged on the monitor. It is easier to see than hear this information, especially when switching among conversations.

Most banks use a combination of brokers and direct dealing systems. Both approaches reach the same banks, but not the same parties, because corporations, for instance, cannot deal in the brokers’ market. Traders develop personal relationships with both brokers and traders in the markets, but select their trading medium based on price quality, not on personal feelings. The market share between dealing systems and brokers fluctuates based on market conditions. Fast market conditions are beneficial to dealing systems, whereas regular market conditions are more beneficial to brokers.
