Im slightly remembered on the flash crash
The May 6, 2010 Flash Crash[1] also known as The Crash of 2:45, the 2010 Flash Crash or just simply, the Flash Crash, was a United States stock market crash on Thursday May 6, 2010 in which the Dow Jones Industrial Average plunged about 1000 points—or about nine percent—only to recover those losses within minutes. It was the second largest point swing, 1,010.14 points, and the biggest one-day point decline, 998.5 points, on an intraday basis in Dow Jones Industrial Average history.[2][3][4]
At this time i was trading currencies very heavily, i say its similar because you could smell something is going to happen back then, i was awake like 2 days and fell asleep while it happened, lol.
So it was here, suddenly people started talking about some mysterious fund that will be payd out, there the market already was tanking.
