Overview
A useful article from Investopedia defining divergence and what the indicator tells you
The study works by detecting divergence between swings on the chart and swings on an oscillator. Swings in this context are synonymous to peaks or pivots.
The image to the right highlights different types of swings
A few definitions:
- The 1st peak refers to the swing that is on the left hand side of the chart.
- The 2nd peak refers to the swing that is on the right.
- A divergence is when the peaks of the price go in a different direction from the oscillator. Price increasing Vs. oscillator decreasing, or vice versa.
- A bearish divergence (shown in red) looks for a series of diverging "swing high"s.
- A bullish divergence (shown in green) looks for a series of diverging "swing low"s.
A line is drawn between the two swings once a divergence is confirmed.

Swings are defined as bars that peak higher/lower than all their neighbors. The more bars beside the peak that make a lower high/higher low, the more significant the swing.
The Swing Sensitivity input dictates how many bars need to make a lower high/higher low than the peak for it to be considered for divergence. An example with Swing Sensitivity = 3 is shown in blue on the image to the right.
Sensitivity also has an impact on the responsiveness of the study. A lower sensitivity value means that swings will be detected faster, as there needs to be less bars on the right of the 2nd peak until a swing is registered. The colored arrow indicated on what bar a divergence was detected.

The Trigger Sensitivity input controls the 2nd peak's right side sensitivity controls and by extension how quickly a peak is detected, the Trigger Sensitivity input controls just that. Lower values means sooner detection of divergence, but more false positives on short swings.
Divergence Lookback

|---|---|---|---|---|
|
Divergence is detected between two swings. The study is limited in how many peaks it can look back through for divergence through the Divergence Lookback Number of Peaks input. If there are multiple peaks that divert in the lookback it selects one according to the Divergence Lookback Use Nearest/Furthest Peak input.

| Divergence Types to Detect | Select whether Regular and/or Hidden Divergence types are detected |
| Oscillator Pivot Alignment Enabled | When enabled and a price swing is detected, the study will look back for a swing in the oscillator to use for divergence detection. If no swing is found then the study will not look for divergence. |
