Real-Time Optimized RTO Watchlist limit what it means exactly?

Question

Hello all,

Could someone please clarify to me what exactly does the watchlist number mean for an user, besides the endpoints that it should connect to?

Does it mean that you can have that number as the maximum ongoing subscriptions, aggregated from all active connections?

Or does it mean that per connection, that is the maximum number of ongoing subscriptions you can have?

So for example if your watchlist size is 2500, and have 4 connections, you can have a total of 10.000 active symbols, or only 2.500 even if you have 4 connections?

Also, why for RTO TCP connections the maximum number of active connections is 5 (you receive errors with too many mounts), but for RTO WebSocket you can go over 5?

Thanks

Thank you for reaching out to us.

The watchlist should be tied to each account, not to connections. Therefore, the number of subscribed items for all connections will not exceed the watchlist size.

To the best of my knowledge, each account is limited to a maximum of five concurrent connections.

However, please contact the RTO support team directly via LSEG Support to confirm these.
