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.
The TRIN, or Arms index, is considered a reliable indicator of the daily direction of the market.
The calculation relates up-volume and up-issues to down-volume and down-issues for the overall market.
TRIN is the ratio of advances to declines divided by the ratio of up-volume to down-volume and is calculated using the following formula:
TRIN = (# of advancing stocks / # of declining stocks) / (up-volume/down-volume)
For example, if the number of advances equals the number of declines and the total up-volume equals the total down-volume, the ratio is 1.0 over 1.0, for a TRIN ratio of 1.0.
If the TRIN is greater than 1.0 this is considered bearish, conversely a ratio less than 1.0 is considered bullish.
