UK trader arrested for May 2010 U.S. Stock market flash crash

It'hard to judge someone like him. I am sure he was kind of a hero at Futex at the time. Spoofing was hot. Everybody( including on ET ) was bragging about it.

IMO he made 3 errors : - His tax evasion scheme. This is so antisocial to maintain a poor appearance to trump authorities.
- His bravado with regulators. In 2008 he was 29. I can picture myself telling the exchange to "kiss my ass" at 22 but not at 29.
- He didn't stop when it became obvious regulators were after spoofers. That is just plain stupid.

I wouldn't like to be in his boots now... I think he will be jailed for a long time.
 
Interesting article.
Re: "using commercially available software"....
I wonder on what platform and which broker he was placing his orders ?
 
A spoofer didn't "trigger" the Flash Crash; real selling did. Prices decline because sellers sell, not because they pretend to sell. Better to read the actual Complaint than the clickbait media.

As far as I know the real problem was not selling pressure, but withdrawal of liquidity by so called "market makers" that aren't really what they claim to be as they don't have to post liquidity at all times...
 
LOL! The SEC is a joke.

A Step By Step Guide How To Crash The Entire Market

While we already noted that the CFTC and the DOJ have gone full scapegoat retard, by blaming the entire flash crash on one solitary trader (operating out of the UK no less), which means that Waddell & Reed should now sue the SEC for hundreds of millions in lost fees and defamation, it is worth re-emphasizing the hubris and the audacity that these "regulators" have, to assume that sophisticated market participants are truly dumb enough to believe any of this is just shocking.

In any event, going with the bullshit story concocted by the confused brains at the CFTC (whose former head when all this happened, is now being groomed by Hillary Clinton to be America's next Treasury Secretary), and for all those who wish to follow in the "rogue" ES trader's footsteps, here is how Navinder Singh Sarao singlehandedly crashed the entire market, leading to the single biggest loss in market capitalization in history.

From the charging document:

Defendants aggressively used both the Layering Algorithm and the 188/289-Lot Spoofmg strategies on May 6, 2010, the 2010 Flash Crash day.

Defendants first turned on the Layering Algorithm at 9:20a.m. CT, placing four orders, totaling 2,100 contracts. These orders were each one tick apart, starting three ticks from the best ask. The orders were modified 604 times over the following six minutes so the orders were always at the third level of the sell-side of the order book or deeper, and then canceled with no executions, as the Layering Algorithm was turned off. While the first cycle of the Layering Algorithm was active, the E-mini S&P price fell39 basis points.
While the first cycle of the Layering Algorithm was active, Defendants bought 1,606 contracts and sold 1,032 contracts.

Defendants' use of the Layering Algorithm and the 188/289-Lot Spoofing intensified throughout the day. At 11:17 a.m. CT, Defendants turned the Layering Algorithm on for more than two consecutive hours, until 1 :40 p.m. CT. During this cycle, Defendants utilized the Layering Algorithm to place five orders, totaling 3,000 contracts. A sixth order was added at around 1:13 p.m. CT, increasing the total to 3,600 contracts.
These orders represented approximately $170 million to over $200 million worth of persistent downward pressure on the E-mini S&P price and, over the next two hours, represented 20-29% of the entire sell-side of the Order Book.
The orders were replaced or modified more than 19,000 times before being canceled at 1 :40 p.m. CT. At that time, the Order Book was severely imbalanced and Defendants' 3,600 Layering Algorithm orders were almost equal to the entire buyside of the Order Book. In total, the Layering Algorithm was on for over four hours and 25 minutes on May 6, 2010.

In addition to the Layering Algorithm, Defendants aggressively utilized the 188/289-Lot Spoofing which intensified the Layering Algorithm's effects. Between 12:33 p.m. CT -1:45 p.m. CT, Defendants placed a total of 135 orders with 188 or 289 lots on the sell-side of the Order Book, totaling 32,046 contracts. Ofthese 135 188/289-lot orders, 132 orders were canceled without resulting in execution.

Between 11:17 a.m. CT and 1:40 p.m. CT, Defendants' actions contributed to an extreme order book imbalance in the E-mini S&P market. This order book imbalance contributed to market conditions that caused theE-mini S&P price to fall361 basis points.

During this two-hour period, Defendants traded 62,077 E-mini S&P contracts with a notional value of$3.5 billion.
On May 6, 2010, Defendants caused an artificially low price to exist in the lead month of the E-mini S&P contract.

So now that you know how to crash the entire stock market singlehandedly, please do. Because this is not a "market."

And finally, this:

In addition to the Layering Algorithm, Defendants frequently manually "flashed" large-lot orders in a variety of lot sizes in the Order Book that were quickly canceled with no intention of these orders resulting in trades. At times during the Relevant Period, the Flash Spoofing was used with and to amplify the impact of the Layering Algorithm. At other times, Defendants' Flash Spoofing was used alone to benefit Defendants' trading strategies

In other words, 5 years after Zero Hedge first explained precisely what happened on May 6, 2010, the CFTC finally admits that the flash crash was not due to Waddell & Reed, but due to HFTs and quote stuffing.

The interesting thing not mentioned here is why no one is mentioning other stocks who dropped even more sharply, e.g. Accenture that went down to a penny? Who is to blame there? Not a single word!
 
Man I'm so glad that the market is so robust that one individual can cause a flash crash. Now that they've finally arrested the perpetrator, I can rest easy at night. I can also rest easy that HFTs are providing so much liquidity and are so great for the markets and for my trading.

Nothing to see here, move along.

Just wait until the talibans and ISIS set up HFT firms, then you'll definitely see the VIX spike! :-/
 
Surely this is bullshit. My guess would be big guns punishing small guy as an example. message is don't fish in our part of the pond..

The worry however is that the us judicial system seems to be a medieval war machine rather. I read details of the system squishing that poor Russian programmer who did steal some worthless piece of software from goldman.. it was totally inadequate proportion of force applied..

Seems that those crazy leftists and conspiracy theoretists are right - American business has way too much power.

I was dreading the end of the empire and now I am coming to the point that I am not sure it's the bad thing.

I am off to Chinese language class!

You plan to start trading the CSI300 future?
 
A bounty-hunter triggered the US investigation into alleged rogue trader Navinder Sarao after conducting their own private investigations into the cause of the £500 billion Wall Street Flash Crash.to be kept secret and would not discuss whether he or she is British.

Mr Stevenson said that his client brought “powerful original analysis” to the US Commodity Futures Trading Commission of market manipulation over a long period. The US government then conducted its own investigations into his findings and came to the same conclusions, he added..
Now we are getting somewhere.
 
re: "Surely this is bullshit. My guess would be big guns punishing small guy as an example. message is don't fish in our part of the pond.."

This is so easily remedied by the exchanges: charge for cancellation orders or throttle them or put a timer on the original order to prevent cancellation within xx minutes.
