My real time data streaming is not working. When I click on the streaming arrow on the lower right corner of a chart screen to enable streaming I got an error message as shown in the attached picture. Data update and data streaming through Strategy Monitor is working fine. This is the first time I use this feature since we switch from WLP to WLD.

I just find out that I need to turn on data streaming for IQFeed under the Preferences and it seems it working now. Thanks.

The image is perfectly ambiguous to both the static and streaming providers.

1. What is the provider of the data for the symbol you selected in the DataSet?
2. Which Streaming Provider is selected in Preferences?

Okay, glad you figured it out :)

Thanks Cone. On related note, if I call up a chart for a symbol that is not supported like $SPX by IQFeed or even for a valid symbol like ONDS on the chart, WLD says "No Data Available" then it crashes. I tried this multiple times and same things happened. I am using WLD version 6.9.23.1.
