Ws mini ticker feed selector v1

WSMiniTickerFeedSelectorV1

Subscribes to a mini ticker feed for a single instrument. The mini.s channel offers simpler integration. To experience higher publishing rates, please use the mini.d channel.
Unlike the mini.d channel which publishes an initial snapshot, then only streams deltas after, the mini.s channel publishes full snapshots at each feed.

The Delta feed will work as follows:

  • On subscription, the server will send a full snapshot of the mini ticker.
  • After the snapshot, the server will only send deltas of the mini ticker.
  • The server will send a delta if any of the fields in the mini ticker have changed.


Field Semantics:
  • [DeltaOnly] If a field is not updated, {}
  • If a field is updated, {field: '123'}
  • If a field is set to zero, {field: '0'}
  • If a field is set to null, {field: ''}
