Trade systems on Forex


Trading with brokers. Foreign exchange brokers, unlike equity brokers, do not take positions for
themselves; they only service banks. Their roles are to bring together buyers and sellers in the market, to
optimize the price they show to their customers and quickly, accurately, and faithfully executing the
traders' orders.
The majority of the foreign exchange brokers execute business via phone using an open box system
— a microphone in front of the broker that continuously transmits everything he or she says on the direct
phone lines to the speaker boxes in the banks. This way, all banks can hear all the deals being executed.

Because of the open box system used by brokers, a trader is able to hear all prices quoted; whether the bid
was hit or the offer taken; and the following price. What the trader will not be able to hear is the amounts
of particular bids and offers and the names of the banks showing the prices. Prices are anonymous. The
anonymity of the banks that are trading in the market ensures the market's efficiency, as all banks have a fair
chance to trade.
Sometimes brokers charge a commission that is paid equally by the buyer and the seller. The fees
are negotiated on an individual basis by the bank and the brokerage firm.
Brokers show their customers the prices made by other customers either two-way (bid and offer)
prices or one way (bid or offer) prices from his or her customers. Traders show different prices because they
"read" the market differently; they have different expectations and different interests. A broker who has
more than one price on one or both sides will automatically optimize the price. In other words, the broker
will always show the highest bid and the lowest offer. Therefore, the market has access to an optimal
spread possible. Fundamental and technical analyses are used for forecasting the future direction of the
currency. A trader might test the market by hitting a bid for a small amount to see if there is any reaction.
Another advantage of the brokers' market is that brokers might provide a broader selection of banks to
their customers. Some European and Asian banks have overnight desks so their orders are usually placed
with brokers who can deal with the American banks, adding to the liquidity of the market.
Direct dealing. Direct dealing is based on trading reciprocity. A market maker—the bank
making or quoting a price — expects the bank that is calling to reciprocate with respect to making a price
when called upon. Direct dealing provides more trading discretion, as compared to dealing in the brokers'
market. Sometimes traders take advantage of this characteristic.
Direct dealing used to be conducted mostly on the phone. Phone dealing was error-prone and slow.
Dealing errors were difficult to prove and even more difficult to settle. Direct dealing was forever changed
in the mid-1980s, by the introduction of dealing systems.
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.
Dealing systems are continuously being improved in order to offer maximum support to the dealer's main
function: trading. The software is rather 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.
Matching systems. Unlike dealing systems, on which trading is not anonymous and is conducted
on a one-on-one basis, matching systems are anonymous and individual traders deal against the rest of the
market, similar to dealing in the brokers' market. However, unlike the brokers' market, there are no
individuals to bring the prices to the market, and liquidity may be limited at times. Matching systems are
well-suited for trading smaller amounts as well.
The dealing systems' characteristics of speed, reliability, and safety are replicated in the
matching systems. In addition, credit lines are automatically managed by the systems. Traders input the
total credit line for each counterparty. When the credit line has been reached, the system automatically

disallows dealing with the particular party by displaying credit restrictions, or shows the trader only
the price made by banks that have open lines of credit. As soon as the credit line is restored, the system
allows the bank to deal again. In the inter-bank market, traders deal directly with dealing systems,
matching systems, and brokers in a complementary fashion.
