Option scanners?

[mizhael]

Is there a good website or option scanner service that can alert us to extreme market movements for potential stocks, such as pending earnings event, call/put volume jump, huge vol jump, etc.?

Thanks!

No! They all hoard that information. You might try this cheapskate website: http://www.interactivebrokers.com/optionsCommentary/elitetrader/
