Essentially what I am trying to do is buy or sell straddles into earnings. When I look at something like zacks or yahoo's earnings calendar it shows me all the stocks reporting earnings tomorrow.... but it takes a long time to go through and find which have options and more importantly which have options that dont have insane bid/ask spreads...
If there was a service or site which spit out a report that said here are the stocks reporting earnings tomorrow that have "liquid" options. Then I can spend my time researching each of those stocks and developing my bias for long/short the straddle.
