Do you provide real-time stock scanning?
StockCharts Support January 27, 2009
Yes and No. Because of the vast amounts of data involved, all scanning systems work with datasets that are slightly older than "real-time." When the market is open, our scan engines are continually updating the final data point for all of the stocks and indexes that they track on a rotating basis. When an Extra or PRO member runs a scan based on the "Last Intraday Update", the scan engines will use a final daily data point that is somewhere between 5 and 30 seconds old depending on when the scan is run.
