CUSUM is a sequential analysis technique that accumulates deviations from a target value over time. By comparing the cumulative sum against defined thresholds, it becomes easier to spot even subtle shifts in price behavior. In our implementation, two separate accumulators—one for upward movements (CUSUM Positive) and one for downward movements (CUSUM Negative)—signal when the change in the underlying price series becomes significant.
