ReadonlylowerLower whisker end (e.g. p5 / min). Required.
Optional ReadonlymedianMedian line inside the box (e.g. p50). Omit for no centre line.
Optional Readonlyq1Box bottom — first quartile (e.g. p25). Omit with q3 for a range-only box.
Optional Readonlyq3Box top — third quartile (e.g. p75). Omit with q1 for a range-only box.
ReadonlyupperUpper whisker end (e.g. p95 / max). Required.
The quantile column names a boxFromTimeSeries / boxFromValueSeries reads.
lower/upper(the whisker reach) are required;q1/q3(the box body) andmedian(the centre line) are optional — omit them for a range-only box (a bid→ask IV segment: whiskers only, no body). Omitting exactly one ofq1/q3is a data error (a box needs both edges or neither).
