Dial/Data errors in put & call vol

["David Shields" <dshields@xxxxxxxxxxxx>]

I'm using Dial/Data to obtain OEX put and call volume historical files. The
symbols are *TOEXC and *TOEXP. I've found substantial errors in these
symbols (for example, starting 11/20/98 there is a block of bad data). Does
anyone else use the OEX put and call volumes (put/call ratio)? If so, can
you recommend a data vendor?

I'm looking for:
   OEX put and call volumes -- end of day
   CBOE equity only put and call volumes -- end of day

Thanks,

David
