or after maket data? I am not able to find a way to show those data, I am wondering if it supports pre- and after market.
I know the datafeed supports it but due to various exchange regulations, EH LAST is sent in a different field from the regular LAST. QuoteTracker does read it and display it on the charts. Other software may not. Which program are you using to access IQFeed? Jerry Medved http://www.quotetracker.com
Not sure what the option is in their software. May want to contact them by phone or chat. I am sure that they have it though, since they do have it in the datafeed.
