The precursor of the stock market originated in 1602 when the
Dutch traded shares of the Dutch East India Company on the
Amster River Bridge, and the formal stock market first appeared in
the United States. The stock market is a place where both
speculators and investors are active, and it is a thermometer of
the economic and financial activities of a country or region. Since
the birth of the stock market, the trading methods of stocks have
been changing with the development of communication tools,
mainly through face-to-face trading, telegraph and telephone
trading, computer Internet trading, and now through mobile
devices trading. Next, we will mainly introduce the relationship
between the stock trading method and the development of
communication equipment from the above aspects.
The main way stock markets
are formed and traded.

This changes everything.Again
Face-to-face transactions first appeared in
the Netherlands, around the 17th century
in the Dutch Republic. At that time, in
order to raise money for the war, the
Dutch government began to issue bonds
to the public to attract investors. These
bonds are often called \"shares\" because
investors receive a share of the company's
profits as dividends.
In the Netherlands, these bonds have become a
necessity for almost every household, and many people
have started to increase their wealth by buying and
selling them. This act of buying and selling government
bonds is one of the earliest ways to speculate in stocks,
and is also regarded as the prototype of the later stock
exchange. The form of trading at that time was very
different from the stock exchange today.

The history of
telegraph
Samuel Morse sent the first telegraph in the
world，“what hath god wrought”
1844.5
Galermo Marconi sent and received the first
radio telegraph
1896.3
What hath God wrought ！
Quicker communication enabled the
creation of a truly national stock
market, as brokers from different cities
could now trade on the same
exchanges. This expanded the pool of
potential investors and increased the
total volume of trade.
Bigger market
The speed of trading allowed for
increased speculation, and many
traders started to rely on short-term
price fluctuations rather than longterm value investing.
More speculative
opportunities
The telegraph's speed of transmission
led to a reduction in information
asymmetry, as all traders could get the
same information at the same time.
This enhanced the overall efficiency of
the market and its ability to accurately
reflect the underlying value of stocks.
Greater Market
Efficiency
All buy and sell orders could be placed
and executed in a matter of minutes.
This increased the liquidity of the
market, making it easier for investors
to both enter and exit positions.
Faster transaction speed

The history of the telephone The use of telephones in China
When audio telephones swept away traditional analog telephones, the
self-service telephone entrustment system based on audio telephone
technology quickly entered the securities business department, from 4
lines, 6 lines, to 16 lines, until the telephone self-service entrustment
system with hundreds of lines.
The success of the telephone self-service entrustment system is that it
solves the pain point of investors who \"have to go to the securities sales
department to trade stocks\".Contributed to several stock booms during
the 1990s.
The introduction of the telephone self-service entrustment system has
made it possible to trade stocks anytime and anywhere, bringing China
into an era of national stock trading.
Telephone technology used for stock trading
This is just the beginning
In that popular era, self-service trading terminals based on touch screens were also placed in the trading halls
of some securities business departments. Huaxia Securities, a large securities company at that time,
established an electronic trading center, which mainly relied on telephone self-service trading, and its
business grew very rapidly. Around 2000, during the most severe crackdown on the securities industry in
history, Huaxia Securities declined, and this electronic trading center also disappeared.Another era emerged.
