balmywinds, that's my "virtual" 120 minute chart. StockCharts doesn't offer 120 minute charts at the moment, so I use a 60 minute chart with 120 minute indicators to simulate it. The individual candlesticks are incorrect for a 120 minute chart, but all of the indicators line up the way they would if it were an actual 120 minute chart.
if you note the periods on the indicators, they are 2x what he uses for 60 min- so he has a very nice way of getting 120 min indicators from Stockcharts.com, although the price bars are still 60 min intervals. nelj
