Swedish Stock Exchange Hit By Programming Snafu 136
New submitter whizzter writes "I was reading the Swedish national news today and an image in a stock exchange related article struck my eye. An order had been placed for 4 294 967 290 futures (0xfffffffa or -6 if treated as a 32-bit signed integer), each valued at approximately 16,000 USD, giving a neat total of almost 69 trillion USD. The order apparently started to affect valuations and was later annulled, however it is said to have caused residual effects in the system and trading was halted for several hours."
