Usage
The Venue sends Moment a Market Data Incremental Refresh to create a new quote, update an existing quote, or delete an existing quote. On connection, the Venue sends Moment a snapshot of all outstanding quotes in the order book, followed by incremental updates. These are all sent as 35=X Market Data Incremental Refresh messages.
Moment does not support messages 35=V Market Data Request and 35=W Snapshot/Full Refresh messages.
