What you need to know about fat fingered errors.

Fat fingered errors have only occurred since the use of computers for trading, which replaced the open outcry method in the 1980s. Before computerised trading, these sorts of mistakes were known as “out trades”. These errors are rather common on the financial market. Fat fingered errors can be caught before they reach the market if the trading house has an automated system within its infrastructure. They are also more often cancelled before they can be completed if the number is very large and exceeds the actual amount of stock on the market.
