FUTR - open interest & liquidity

[Dean Chahley <maui@xxxxxxxxx>]

RT's,

I trade various future markets, and am wondering if any of you trade one
market with different contract expirations? (S H8, S K8, & S N8) It's been
suggested that I use open interest to determine whether a market has
sufficient liquidity or not. Does anyone know of any websites that contain
open interest statistics for each market?

Regards,
