A committee called the Options Price Reporting Authority, or "OPRA," processes securities information. Specifically, market information generated by securities options trading in the United States. The information includes last sale reports and quotations, besides other information relating to the number of open interest, options contracts traded, end of day summaries, and more. As a subscriber to OPRA, you have the right to use options information "internally’" i.e., within your own organization, or yourself, if you are an individual.
