ROCX is a modified ROC (Rate Of Change) indicator displaying an absolute or relative price change.
It is calculated as (current – previous) / previous, not (current / previous – 1).
Three display modes:
- Absolute value;
- Percent of the previous value;
- 1/10 percent of the previous value.
The indicator has three input parameters:
- Period – calculation period;
- Applied price;
- Mode – mode:
- Absolute value – absolute value;
- % value – percent of the previous value;
- %1/10 value – 1/10 percent of the previous value.
Calculations:
Absolute value:
ROCX = diff
% value:
ROCX = 100.0 * diff / PrN
% 1/10 value:
ROCX = 1000.0 * diff / PrN
where:
diff = Applied price - Applied price[Period] PrN = Applied price[Period]
A positive value indicates the upward direction of change, a negative value means the downward change direction. Greater values mean faster changes.
