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.
On Balance Volume
On Balance Volume ("OBV") is a momentum indicator that relates volume to price change. On Balance Volume is a running total of volume. It shows if volume is flowing into or out of a security. When the security closes higher than the previous close, all of the day's volume is considered up-volume. When the security closes lower than the previous close, all of the day's volume is considered down-volume.
On Balance Volume is calculated by adding the day's volume to a cumulative total when the security's price closes up, and subtracting the day's volume when the security's price closes down.
