Options Price Reporting Authority (OPRA) divides its services into two main areas: a basic service for all options other than currency derivatives and an “FCO service” for information on currency options. The organization includes the American Stock Exchange (AMEX), chicago Board Options Exchange (CBOE), Boston Options Exchange (BOX), International Securities Exchange (ISE), Pacific Exchange (PCX), Philadelphia Stock Exchange (PHLX), BATS Options (BATS), Miami International Securities Exchange, NYSE Arca and Nasdaq OMX BX Options.

OPRA MPS data rates are more than 60 times higher than in the stock market,[3] and options data accounts for well over 75% of all market data. [2] As an example of an option chain with OPRA offerings, you can see the following example from Apple, Inc. The left column displays the optional sticker, in which case they are all calls with different exercise prices that expire in August 2019. Then the last trading period, money, letter, last price and last change are moved with the volume and implied volatility of the last price for that option.
