Hi,

I'm developing a proof-of-concept .NET data adapter for LS and I'm still getting the hang of it so I apologise in front if I ask something obvious.

As the adapter feeds the current stock data to LS clients, I definitely want to have an item in the MERGE mode for each of the listed stock, e.g. PLVA, ERNT. So far so good.
But I would also like to have the ability for the clients to subscribe to an item that represents "all traded stocks for the current trading day". So I figured I need an item "ALL_TRADED" in the COMMAND mode, where I could ADD new stocks to the table as they get traded. The schema (fields) and the data of "ALL_TRADED" and every specific stock's items are identical. After a (too) long introduction my question would be is there a way to setup things so that if a subscription is made to the "ALL_TRADED" item I do not have to call listener's Update event for each of the specific stock's items that are already included in the "ALL_TRADED" item?

Thanks.
