Options analysis program?
Longtime reader/lurker and decided to register and dig in a bit.
Am doing some work on a project and I'm curious for your thoughts. I'm looking for a program to get up to date and historical data on put/call ratios of individual stocks. I know I can get overall put/call ratios for all equities in general from the CBOE website, but I want it for individual stocks. I basically want the best options analysis site online; a place where I can identify possible arbitrage opportunities (conversion spreads). Cost isn't really a factor here...
So far I've found:
Bridge Information Systems
Thompson Financial News
Broker Services Group of Automatic Data Processing
If your recognize any names or have some thoughts I'd love to hear it, especially before I subscribe to some shitty service.
