"I am here in Peru where the only news is about Peru." ... clearly _not_ the only news ...
but just to bring things into focus, a view on what has happened ...
http://business.financialpost.com/2012/09/20/flash-crash-or-a-turning-point-for-oil-prices/“In their report on the 2010 equity market crash, the SEC and CFTC staff found that “against a backdrop of unusually high volatility and thinning liquidity, a large fundamental trader (a mutual fund complex) initiated a sell programme to sell a total of 75,000 E-mini contracts (valued at approximately $4.1 billion) as a hedge to an existing equity position”.
The CFTC knows that somebody did something stupid with $4.1Bn ... and others profited.
In the course of the investigation TPTB realise that one of the little people managed to
make some money, and figured that he had to be doing something illegal because the game
is rigged in their favour with secret order types to allow them to front-run and to queue-jump.
(read Scott Patterson's? book)
At this point there are two theories :
a) That TPTB want to avoid exposing their wrongdoing and their algorithms in court hence
bringing a case against any US players is impractical; and
b) TPTB want the code that generated the profit for themselves
So, just before the SoL runs out, they pick the Armstrong option. (Go see "The Forecaster")
Arrest (and extradite) on very doubtful (later no) grounds, demand the source code, and hold
in jail for contempt of court for as long as the need exists. Eventually offer a choice of
pleading guilty or n years in jail, where n > expected life.
What could go wrong? It looks like things have not worked out as planned.
The source code may not have been published immediately, but the inner workings and the
methodology are known. So there is likely to be a small army working on implementing
and improving the code right now, and Asia excels in industrial scale reproduction ...
And contrary to the published propaganda the system is no more secure. TPTB would love
you to believe that the avalanche was due to one rogue snowflake, ridiculous though that
idea is. Maybe the bulldozers driven by the big banks? Hardly. How about the Federal
Reserve Bank that built up the mountain using the US Taxpayer's money? They really do not
want attention drawn to that ...
For recent details ...
