The man behind the Wall Street 'flash crash' in 2010 has claimed he did nothing wrong, at Westminster Magistrates Court.
Navinder Singh Sarao was last week granted a one-week extension to raise £5.05 million to secure bail. Mr Sarao is fighting extradition to the US on accusations from the Department of Justice that he contributed to the "flash crash" on Wall Street five years ago.
"I've not done anything wrong apart from being good at my job. How is this allowed to go on, man?" Mr Sarao said in a brief outburst.
He applied for bail on £50,000. But it was rejected by Judge Elizabeth Roscoe.
Mr Sarao is accused of illegally making £26 million ($40m) through his trading firm Nav Sarao Futures. The DoJ claims he used an "automated trading programme" to manipulate financial markets, causing $800bn being wiped off Wall Street markets in a matter of minutes, although it soon recovered.
