JD, I'm watching the daily on stockcharts off and on during the day, to see if the price is outside the upper bbs, I always have QT 4 min on all day while in a stock.It's the time and sales on QT that tells me when everyone is dumping 4 min is the chart frequency i use. a lot of daytraders use 5 min so 4 min puts you one step ahead. JMO. scalpers use 1 and 3 minute charts
