| Anchor | Session (default), Week, Month, Quarter, Year | When the running sum resets. Session restarts each trading day; the wider anchors carry the average across the whole period. |
| Source | hlc3 (default), Close | The price each bar contributes. hlc3 is the average of the high, low and close — the classic choice, and steadier than the close alone on a wide bar. |
| Bands | Up to three pairs, off by default | Each pair draws above and below the centre line, with its own colour and a soft fill. |
| Band basis | Standard deviation (default), Percent | Volume-weighted σ, or a fixed percent offset from the line. |
| Multipliers | 1, 2, 3 by default | How far each pair sits from the centre, in σ or in percent. |
