What isfat finger

Fat finger error in financial markets refers to keyboard entry or mouse click mistakes that place orders on a much larger scale than intended, at an incorrect price or wrong stock, among other entry errors. Trading firms’ automated systems can detect and cancel such orders, especially those that exceed the stock available in the market.

While fat finger errors are usually harmless, they can negatively impact the market. For instance, when a trader mistakenly enters an order to sell a million shares instead of a thousand, it can be executed with any buy order at the bid price, leading to a significant impact.

To prevent such errors, brokerage firms, investment banks, and hedge funds set up filters that alert traders to entries beyond the usual market parameters or entirely prevent erroneous orders from being placed. U.S exchanges, including NYSE, NASDAQ, and AMEX, also require reporting of such trades within thirty minutes of execution.
