I'm looking to connect with people with experience using Splunk in financial markets. What experience do you have and are you interested in joining an informal user group I would create?
Yes, I use it for financial markets. I have dozen's of API's streaming data to it and also stream Goole Trends data to it. I do a lot of sentiment trading
This doesn't quite answer your question, but I suggest you take a look at the recordings of the recent .conf presentations from the financial services sector: http://conf.splunk.com/sessions/2017-sessions.html#industries=Financial%20Services&
That could give you some great places to start and people to reach out to.
