Hello,I'm looking for historical data for options on futures (commodity futures) as well as an ongoing data provider for day to day pricing.I've checked out a few providers (CSI, Optionmetrics) and they seem okay but I was wondering if anyone has had any experiences they'd be willing to share. I've used CSI in the past for futures data and found their reliabiliy to be poor both in service and data integrity. The cost seems a little steep as well ($125 per year, per contract). Is that close to market rate? If anyone has used a provider that stood out or know of other companies I've missed, I would be grateful if they could share them with me. r

Have you tried the exchange web sites. This one is for LIFFE Euronext but i'm sure the CBOT and CME et al will provide the information you are afterhttp://www.euronext.com/landing/liffeLanding-12601-EN.html

Thanks for the feedback. I looked into the CME and CBOT and they do provide the data (nymex contracts are included as well).r

I think we use a service called tenex (sp?) for both the underlying and vol data.
