SGD,
"Everybody" isn't using any one particular intraday scanning program. There are many. If you have CyberTrader it has a built-in scanner called CyberQuant. There are a number of scanners that use the TAL (RealTick) data feed i.e., mTrader, iWatch, Sort Wizard, Stormtracker, OzScan, etc; then there's others that use their own feeds like First Alert and TradeStation. Also, I'm sure there are some web-based scanners although I don't know if they're realtime.
