To be listed on the NYSE, a company must meet specific financial requirements. High-frequency trading (HFT) is a significant part of modern trading, accounting for a large percentage of market operations, but can also lead to flash crashes, dramatic declines in security prices in very short timeframes. Companies like HFT Brokers in Poland and Nanex are notable players in the HFT space, providing various services to traders and requiring regulatory oversight.

14. HFT is the reason of flash crashes
A flash crash is a very rapid, deep, and volatile fall in security prices occurring within an extremely short time period. A flash crash
frequently stems from trades executed by black-box trading, combined with high-frequency trading, whose speed and
interconnectedness can result in the loss and recovery of billions of dollars in a matter of minutes and seconds.
Two notable flash crashes have occurred in history:
April 23, 2013, Flash Crash
Singapore Exchange which lost $6.9 billion in capitalization and
saw some stocks lose up to 87 percent of their value
May 6, 2010, Flash Crash
$4.1 billion trade on the NYSE resulted in a loss to
the Dow Jones Industrial Average of over 1000
points

15. Market need to control HFT via
algorithmic tests
When the market operates
normally (left subplot), almost all
of the HFT agents are in control of
their inventory (greenish color). In
crash period (right), most of the
HFT agents gain large inventories
(red) and the network is highly
interconnected: over 85 percent of
the transactions are HFT-HFT.

high-frequency trading is
our future
