OptionalappearanceOptionalchartThe chart type this chart is showing (a registered chart type id), if the host tracks one.
OptionaldrawingsThis chart's side of drawing sharing. Without one it never shares drawings.
OptionalintervalThe interval this chart is showing, if the host tracks one.
OptionalonShow chartType on this chart. Return false to refuse one it cannot draw,
which leaves the member on its own type and asks again on the next change.
Omit to keep this chart's type out of the group's reach.
OptionalonApply the interval synchronously; return false to refuse an unsupported token.
OptionalonLoad symbol into this chart. The group calls it; the host does the work
(fetch bars, series.setData). Omit to make the member symbol-read-only:
it still broadcasts its own changes, it just never follows anyone else's.
OptionalsymbolThe instrument this chart is showing right now, if the host tracks one.
Visual settings only; no instrument, timeframe, study or trading state is copied.
