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

"Using data from Nasdaq OMX Group Inc., Hendershott and two co-authors wrote last year that speed traders smooth out pricing errors and provide liquidity on some of the most volatile trading days."

hmmmm


So on the day of the flash crash they provided liquidity? I seem to recall HFT's saying they all turned their machines off. Just like every other market maker in history has done when the shit hits the fan. They run and hide.

there's no public service being done by HFT's. They take it when its good and hide when its bad.

Hard to tell if the academic [Terrence Hendershott] is the whistle blower or an investigator hired by the CFTC to follow a tip off.

My bet is that he was not the actual whistleblower. Notice how even he could not conclude that Nav's trading had contributed significantly to the flash crash.

...he would have a million bucks here and there under tree roots and such. Not the whole thing, but you know a safety fund. What I have learnt from this ordeal that nothing beats the good ol' money under the mattress (well, tree roots) approach. Than any confident of yours can get it, no signing of papers needed...

Careful....remember a whistleblower was required to take Bernie Madoff down.....the US government definitely could not do it.

1. The whistle blower didn't take Madoff down, the market did.
2. Technically speaking the guy was an outsider doing old fashioned private eye accounting checks and common sense, not a whistle blower.

This it totally wrong. A guy by the name of Harry Markopolos took him down.

Harry is a member of the ACFE and is a professional forensic accountant specializing in financial industry fraud.

on your behalf. The guy you mentioned exposed Madoff several times, and big nothing happened. Then when the market turned down and his customers started to pull their money out of the fund, the Ponzi collapsed. Madoff gave himself up, if you recall....

Read the newspapers, you don't have to believe me. The Madoff case is actually a counter example for whistle blowers, if the entity is well protected, no whistle blown can harm it, apparently...

The whole idea of trying to pin the flash crash on this guy stinks to high heaven. Why even mention the flash crash? He is a clear abuser by spoofing and that is enough. Trying to make a correlation to the flash crash is some kind of politically motivated affair.
 
Flash Crash Scapegoat Nav Sarao Complained More Than 100 Times About The Real Market Manipulators

Several weeks ago, when the CFTC and DOJ's laughable attempt to scapegoat the May 2010 flash crash on the actions of a live-in-his-parents-basement UK trader, we explained "Why Sarao Is The Flash Crash Patsy: He Threatened To Expose The "Mass Manipulation Of High Frequency Nerds."

It now turns out that he not only threatened to expose the real market manipulators, but he acctually did it. More than 100 times.

Navinder Singh Sarao, the trader arrested last month on U.S. charges he manipulated futures prices and contributed to the May 2010 “flash crash,” leveled claims of similar misconduct against other traders before his arrest.

Mr. Sarao complained to the Chicago Mercantile Exchange, where he traded futures contracts, more than 100 times over the past several years about traders he believed were engaging in manipulative conduct, people familiar with the matter said.

His last complaint came just weeks before he was arrested on Justice Department charges, one of the people said.

Who are the real manipulators, we ask rhetorically:

Previously released documents have shown Mr. Sarao urging exchanges to target high-frequency trading practices he viewed as manipulative, but the frequency and extent of his complaints weren’t known. His complaints underscore the extent to which Mr. Sarao viewed his own trading as a legitimate counter to other high-speed traders.

Mr. Sarao appears to have filed an unusually large volume of complaints. “That would be considered a high number,” said Ray Cahnman, a longtime futures trader and chairman of the proprietary trading firm Transmarket Group LLC. “Most people would break down before they get to 100 because they realize the complaints aren’t going anywhere,” he said.

Sarao's complaints got him somewhere: straight to prison. And now we know why.

As for Sarao's complaints going anywhere else: fear not, they will - just as soon as the market crashes. Because not only will the next market crash be epic, it will be blamed entirely on the same HFTs that for the past 7 years worked in tandem with the central banks - the source of all capital misallocation decisions - in the creation of the biggest asset bubble of all time.
