What was the essential problem behind the flash crash on May 6, 2010 regarding algorithmic trading?
What will be an ideal response?
Because algorithms controlled nearly 70% of the actual cash in the market, it was very hard to trade stocks when the algorithms were staying out of the market, because the parties swap stocks for cash. If the computers that control all the cash are staying away, even those that want to do trades cannot, because there is no cash available. As a result, during the flash crash, many stocks offered for sale were not purchased because the high-frequency trading algorithms hoarded cash instead of making purchases. The sellers assumed (incorrectly) that the reason the stocks were not selling was because their asking prices were too high, and they automatically started to slash prices, causing the stock market to drop.
