Lost $440M in 45 mins

The hidden cost of hiring
tier 3 software engineering team
and why HFT firms avoid it?

It took Walter R
17 years to build
a top HFT firm
in Wall Street

but in August 2012
it was brought down
to its knees
by a System Administrator

The story...

To understand the story better
remember these key components
of the HFT System

1. OMS- receives and manages trade orders
2. SMARS - the algorithms engine
3. EV - execution venues like NSE, BSE, NYSE

Flow of execution:

1. Trader places order to OMS
2. OMS forwards to SMARS
3. SMARS does the calculation and strategy
4. EV processes the request of long or short

Simple..

Back to the story,
The day before incident Joe ( Sysadmin )
was tasked to deploy
a new piece of code (RLP)
to SMARS

SMARS a distributed system
with 7 servers

Joe deployed RLP
on first 6 servers
but missed the 7th

The legacy code
had a feature flag
that toggles
a system called
Power Peg

Power Peg dissects
a large order to smaller
orders and takes position
in seconds

interestingly,
PP was deprecated
6 years ago by the firm

but as of today
some genius decided
RLP will use
the same feature flag
used by Power Peg

Moving on..

Night before incident,

Joe was alone in office
Joe tests few servers
they worked as expected

Joe activates feature flag
for all servers
and logs off

Next morning
the market opens,

First 6 SMARS server
worked as expected

the 7th server
receives ~181 orders

and boom 💥

Within 45 mins
Power Peg places
long position worth $3.5B
and short position of $1.3B

All hell breaks loose

Knight capital will now have to clear
$3.5B in payments in 3 days
which they don't have..

Thomas Joyce the then CEO
went crazy and a spine chilling
incident grasps the entire
Wall Street
-------

So what went wrong?

Joe ( Sys Admin ) was the tail
of the problem
a mere executionist

The root of the problem
was somewhere else

Big problems:

1. Deprecated code still lies in active prod code
2. No automated deployment process
3. No second technical reviewer for Joe
4. No regression testing suites

We often hear "If it works don't touch it"
This is the worst advice for software engineers

Every action that the software does
should be:

1. Tested
2. Documented
3. Reviewed

Else we end up in the Knight Capital fiasco

Goldman Sachs
had to settle the dues
of $440M

Knight Capital was eventually
sold within 2 years

Bad software engineering practices
and failed software architects
brought down a good company in a flash

---

Key takeaways:

1. Software Engineering is an orchestra of DevOps, Development, QA, Processes etc.

2. Processes and Systems makes software predictable and less erroneous.

3. Great coding standards is a culture that leadership has to imbibe from day 0
