Options Symbology Initiative
The options industry, led by the Options Clearing
Corporation (OCC) have initiated an industry wide effort to simplify
the symbology used to describe an individual options series. The
single letter code to represent a series strike price used by
the Options Price Reporting Authority (OPRA) will no longer be
supported by the end of 2009. In addition, explicit information
about a series' expiration will be included in the symbology in
order to eliminate many alternative symbols assigned to options
classes for LEAPs and when there are more strike prices than letters
in the alphabet (wraps). In the future, this page will contain
information about testing and implementation of different aspects
of this effort. The following links are for Phlx external file
formats (trading systems and clearing systems) that are affected
by this industry initiative:

The formats for the customized Matched Trades and
Open Order files are being e-mailed to the appropriate recipients
at the firms.
