Context

  • id?: Get | Update (Update is assumed if omitted)

  • gridLines: vertical | horizontal | both | none
  • minorGridLines: vertical | horizontal | both | none (currently Y axis only)

All Update fields are optional.

Behavior

Other supports:

  • Get: returns current settings for most fields listed in Context.
  • Update: applies one or more miscellaneous settings.

Notes:

  • showNavigator, plotHover, and showGoToLatest are updateable but are not returned by Get.
  • hiddenItems is a chart-level visibility mode; it does not mutate individual plot or annotation visible fields.
  • realTimeCboeBzx updates can emit host notification CH_HOST_PROPS_CHANGED.

Comparison mode

comparisonMode controls how multiple plots are normalized when drawn on one axis:

  • None: no normalization; chart uses the first plot’s price range
  • Percent: plots values as percent change from the first visible bar
  • Value: plots absolute value change from the first visible bar

Historical last-trade prices

useLastTrade is a chart-wide data preference. When enabled, daily and higher historical bars use the last traded price as their close, falling back to close/settlement when the last-trade field is empty. Studies and exports consume this selected close. Quote snapshots, including reconnect snapshots, do not modify these historical bars; live trades still update the current bar. Quote displays remain unchanged. Minute and tick data are unaffected, and the preference is retained when switching intervals.
