When charting any of the studies, the argument coloring is red, green then blue. For example, on a Moving Average chart [9, 18, 40], the 9 day would be the red line, 18 day would be the green line and the 40 day would be the blue line. The argument order is displayed on the chart next to the study name.
Volume and Open Interest
Volume is the total number of contracts traded for each day. For weekly and monthly data, the volume figures are the average daily value. Official volume figures for futures data is not normally transmitted until the next day. This is why volume and open interest prices are always a day behind.
Volume is represented by the vertical lines on the bottom of the chart.
Open Interest applies to futures contracts only, and is the total number of outstanding contracts. Open interest is represented by the horizontal line above the volume on the bottom of the chart.
