Name `Lite`	Type	Required `Default`	Description
stream `s`	string	True	Stream name
selector `s1`	string	True	Primary selector
sequence_number `sn`	string	True	A sequence number used to determine message order within a stream. - If `useGlobalSequenceNumber` is false, this returns the gateway sequence number, which increments by one locally within each stream and resets on gateway restarts. - If `useGlobalSequenceNumber` is true, this returns the global sequence number, which uniquely identifies messages across the cluster. - A single cluster payload can be multiplexed into multiple stream payloads. - To distinguish each stream payload, a `dedupCounter` is included. - The returned sequence number is computed as: `cluster_sequence_number * 10^5 + dedupCounter`.
feed `f`	Trade	True	A public trade matching the request filter
