Watchlist Operation

You can use inserts and deletes to modify watchlists.

Watchlist updates are interpreted as error conditions and no action is taken.

Modifying the market data watchlist causes the adapter to subscribe to or unsubscribe from real-time data on symbols. Modifying the order book watchlist causes the adapter to subscribe to or unsubscribe from order book data on symbols.

• Insert
  A watchlist insert triggers two actions in the adapter: subscribing and publishing.
• Delete
  A watchlist delete triggers two actions in the adapter: unsubscribing and marking records stale.
