BIG DATA IN FINANCE

OVERVIEW OF THIS TALK
• Flavors of big data in finance	

• Technology map for big data in finance	

• Wheel of reincarnation	

• A touch of history	

• Role of visualisation	

• Frameworks	

• Real Time HFT

2
BIG DATA AGAIN
• Big

data is not a “crystal ball”	

• The value from big data can only be extracted
when there is precise business problem to be
addressed	

• Business problem has to be understood and well
defined at the first place	

• Business to data mapping	

• Better business predictions = difficult process	

• Analysing big data	

• Data scientists to examine the data and extract
critical information such as customers buying
habits - need for experts	

• Catalogue data assets (10% of data may actually
mean something)	

• Privacy	

• No clear access controls to access data?

FLAVORS OF BIG DATA IN
FINANCE
• Structured
• Market data feeds	

• Big and fast	

• Order flows	

• Execution info
• Unstructured
• News 	

• Research

WHEEL OF REINCARNATION
T. H. Myer and I. E. Sutherland. On the design of display processors. Communications of ACM, June 1968, 410-414.

STRUCTURED DATA

11
NYSE
New York Stock Exchange started as very	

low-tech place. In 1779, the NYSE was a
bunch of guys standing around a
buttonwood tree at 68 Wall Street shouting
at each other on days when it didn’t rain or
snow.

In 1794 we see the first big
technological solution: the roof.

12
NYSE
Everybody moved inside, to the Tontine	

Coffee House at the corner of Water
and Wall streets. Hands, roofs, chalk (oh
technology)!

1n 1823, the Difference Engine was
invented by Charles Babbage “I wish to
God these calculations had been
executed by steam.”
TECHNOLOGICAL INVASION
- SIMPLER ERA
Before telegraphy, in 1850s, the sky over 	

Wall Street was open and clear
BUT yo
u had t
o know
to part
Morse
icipate
Code
in the m
a
(Morse
, 1837) rket!

It took only a short time for telegraphy’s
compression of time and space to transform
the scenery. Everybody had to have it!
14
TICKER TAPE
A huge success (as important as the roof, hand
signals, and the telegraph). People use jumbo
magnifying lenses - people traded faster than
the machines, so delay meters were installed.

All that ticker tape also made for nice
parades. Here group of specialists
celebrating the one-millionth bagging of a
buy-side trader.
AND MORE TECHNOLOGY
Ticker tapes (an enduring market
visualisation) are still with us today.

ROLE OF VISUALISATION
Dynamic market view: Oculus Info’s
Visible Marketplace - portfolio
visualisation. 	

!

Not very dynamic on paper. 	

!

Another reason to be glad we have
web browsers.
MAP OF THE MARKET

Map of the Market , the classic big picture of whole market visualization.	

It was invented by Marten Wattenberg, now at IBM Many Eyes.

REAL-TIME REAL-TIME REAL-TIME
• Everything

is moving to real time	


• Everything

is moving towards continuous time	


• Everything

is moving towards mobility (anywhere, anytime)	


• Also

GPU for high-frequency trading (HFT)	


• GPU

alongside FPGAs receiving stream of market data to increase the accuracy of
the strategy, or even to suggest change in the algorithm used as market conditions
evolve	


• GPU

Direct enables a GPU to talk directly to the FPGA, receiving data from it into
a kernel, which may be preloaded to perform its magic once the data is available	


• Hadoop

+ GPUs
