Kinds of Exchange Systems-Trading with Brokers

Foreign exchange brokers, unlike equity brokers,
do not take positions for themselves, they only service banks.

Their roles are:

• bringing together buyers and sellers in the market;

• optimizing the price they show to their customers;

• quickly, accurately, and faithfully executing the traders' orders.

The majority of the foreign exchange brokers execute business via phone.
The phone lines between brokers and banks are dedicated, or direct,
and are usually in-stalled free of charge by the broker.
A foreign exchange brokerage firm has direct lines to banks around the world.
Most foreign exchange is executed through 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.

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 the narrowest 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.

Brokers cannot be forced into taking a principal's role if the name switch takes longer than anticipated.

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.
