custom StreamingDataProvider Sample

does anyone have the sample about streamingDataProvider
or StreamingDataProvider API Document ?

 

quote window can use dde ( ref. http://www.facebook.com/pages/Wealt...-lab-5-de-dde-streaming-provider/322172392225
)
but how to enable streaming in chart window ?

 

Here is one I made and works perfectly so far

 

wow, that's what I want !
Can you give me some hints or sample code to achieve?

ps. my Broker Quote APP can offer realtime quote via COM or DDE.

Regards,

 

any code sample, or API ?
