International Securities Exchange Increasing Data Offerings
The International Securities Exchange, the world’s largest equity options exchange, announced today that it is launching a historical market data offering. They exchange did this in response to both member and investor requests for information and market data to help improve trading efficiency. Historical tick market data is the most recent component of ISE’s overall market information initiative which includes previously announced depth-of-book and sentiment market data offerings.
Their initial product offering will include ISE tick data, trades and quotes, in addition to comprehensive Options Price Reporting Authority (OPRA) tick data, delivered on a daily basis through a complete end-of-day file. Historical market data, which was not previously available as a complete, raw end-of-day data source, can be used for multiple functions, including back-testing of trading models, post-trade analysis, compliance and time and sales queries.
To begin with the International Securities Exchange will make two historic data offerings available. They will have an annual subscription to an end-of-day file and the ability to make ad-hoc requests for specific time periods. The end-of-day data will be available as a flat file accessible from an FTP server over the Internet. The ad-hoc requests will be processed and delivered on a portable hard-drive device which can be reused by the client. In order to make this data accessible and cost-effective, both offerings will be delivered as compressed files to reduce delivery back-ups.
