Hi
I've worked on Authoring,charting,data applications for investment banker and also used by their analysts. I've experience with US market and europe market exchanges. Now there are two things
1) I assume you have access (credentials) to access a particuler exchange data (could be anything like charts,metrics,market or estimates data) and we develop an windows application according to your requirement and we render the data or chart onto it (by pulling real data from the exchange).
2) We replicate a similar kind of system which would be real data but it would just simulate the stuff like that.
For your reference I've worked with Investar , Bigcharts, Datastream ....etc application and I know what I'm talking of. so let's discuss this and we can take up from there.
Cheers
