9. The method according to any preceding claim wherein the at least one resource other than the first resource comprises a resource related to the first resource.

10. The method according to claim 9 wherein the at least one resource other than the first

resource comprises a resource whose value is affected by a change in the value of the first resource.

1 1 . The method according to any preceding claim wherein the one or more criteria comprise a value or a change in the value of the first resource greater than a predetermined amount.

and in response to receiving the observation request, transmitting notifications including the value of the one or more resources identified in the observation request.

17. The method according to claim 16 wherein the at least one resource other than the first

resource comprises a resource related to the first resource.

18. The method according to claim 17 wherein the at least one resource other than the first resource comprises a resource whose value is affected by a change in the value of the first resource.

19. A computer readable medium comprising instructions which when implemented on a
