RT Charts
Janet,
I quit using StockCharts RT data because it isn't streaming data. You have to refresh it each time you want to see current prices on your charts. There is also a feature available that will auto refresh your charts at 15, 30, or 60, second intervals.
Something else I got fooled on when I upgraded to RT was that I still couldn't use the scan capability for the current day until 15 or 20 minutes after the market opened. And I was told that RT chart data did not imply RT scanning data. The scanning data could be current, or it could be as much as 20 minutes delayed.
Hope this Helps,
Casey
