I want to trade the S&P 500 Volatility Index but I cant find data that isn’t delayed by 15 minutes. One minute updates is alright, one second is better. I want to be able to display the chart on my screen, in a browser window is fine. I don’t want to have to subscribe to a service that provides access to the whole market when all I want is this one ticker, but if I have to do that could I get a recommendation on the best service to use for my needs?
