The Price Change algorithm can be used with any instrument and calculates the deviation of the last trade price from the average on an interval. The percentage value shows how close the current deviation is to the max deviation, that was detected on the interval.
The algorithm is controlled by the Training period, and is needed to calculate the average price, as well as the max deviation from it on the given time interval. All the values will be shown on the Circle widget.
