Hello.
I'm writing connector and started from most easy StreamingDataProvider. It works now and i see exchange in my own log, where my SDP writes. But how to see these data in WL7?

Hello,
You can see it working in a streaming chart (Help > Charts > Streaming Charts), for example. Another useful tool is the Streaming Data Testbed in the Data Manager > Streaming Providers tab.

When i try open chart for created dataset (not linked) it says something like: couldn't obtain historical data for symbol blabla. Then it clears symbol field and pressing to streaming button connects to provider but didn't start update.
This means the backfill data cannot be found across the historical data providers in Data Manager > Historical Providers. You have to activate a suitable h. provider capable of delivering the data.
i.e. streaming data provider can't work without corresponding history data provider, right?
Yes. To test your streaming provider in a headless way (without a chart which has to load some historical data for backfill), follow suggestion in Post #1 above.
i did, but such way to check data i can only write it to log. Ok, thanks.
