Many binary option "brokers" have been exposed as fraudulent operations. In those cases, there is no real brokerage; the customer is betting against the broker, who is acting as a bucket shop. Manipulation of price data to cause customers to lose is common. Withdrawals are regularly stalled or refused by such operations; if a client has good reason to expect a payment, the operator will simply stop taking their phone calls. Though binary options sometimes trade on regulated exchange, they are generally unregulated, trading on the Internet, and prone to fraud.
AMEX (now NYSE American) offers binary options on some exchange-traded funds and a few highly liquid equities such as Citigroup and Google. On the exchange binary options were called "fixed return options" (FROs); calls were named "finish high" and puts were named "finish low". To reduce the threat of market manipulation of single stocks, FROs use a "settlement index" defined as a volume-weighted average of trades on the expiration day. AMEX and Donato A. Montanaro submitted a patent application for exchange-listed binary options using a volume-weighted settlement index in 2005. CBOE offers binary options on the S&P 500 (SPX) and the CBOE Volatility Index (VIX). The tickers for these are BSZ and BVZ, respectively. In June 2009 Nadex, a U.S.-based exchange, launched binary options for a range of Forex, commodities, and stock indices' markets.
