Hi there,

I have developed tcp server and client for Trader to view live rates of Indian market. (somewhat like http://www.interactivebrokers.com/en/p.php?f=tws)

My application sends Live tick data of each and every stocks to client but some of user want to get data of specific 4-5 stocks but i don't want to create something new for it.

Is it possible to publish only requested stock rates to specific client like we do in webservices we get what we ask for.

Please help.

You probably are looking at something similar to OPC (http://www.opcfoundation.org/[^]). In OPC, the server would have a list of all items and the clients can subscribe to what ever item they want. The client would get the updates only for the subscribed items. You should be able to implement something similar to this for your server/client.
