Customizing indicators

This page explains how to configure, add, and manage indicators in the DXcharts Android SDK.

You can perform the following actions:

  • Add custom indicators (addStudy).

  • Set available indicators (setAvailableStudiesByUuid).

  • Manage favorite indicators (setFavoriteStudiesByUuid, addFavoriteStudiesByUuid, removeFavoriteStudiesByUuid, removeAllFavoriteStudies).

Core concepts​

  • StudyUuid: An enum class whose entries are objects containing the UUIDs of indicators.
  • StudySettingsItems: A generated object that contains constants of StudiesSetting.
    • It is generated automatically and cannot be modified.
    • Use it as a source for creating or copying StudiesSetting objects.

Adding or replacing custom indicators​

Use addStudy to add a custom indicator based on a base configuration.

  • If you specify a new UUID, the indicator will be added to the list.
  • If the UUID already exists, the existing indicator will be replaced with the new settings.
studiesRepository.addStudy(
  study = StudySettingsItems.sma.copy(
      uuid = "NEW_SMA",
      title = "SMA50"
  )
)

Setting available indicators​

Use setAvailableStudies to define which indicators are available in the UI.

studiesRepository.setAvailableStudies(
  setOf(
      StudySettingsItems.aroonOscillator,
      StudySettingsItems.bollingerBands,
      StudySettingsItems.adx,
      StudySettingsItems.roc,
      StudySettingsItems.zigZag,
      StudySettingsItems.sma.copy(uuid = "NEW_SMA"),
  )
)

Setting favorite indicators​

Use setFavoriteStudiesByUuid to define the list of favorite indicators. This method replaces the current favorites with the specified ones.

studiesRepository.setFavoriteStudiesByUuid(
  setOf(
      StudyId.AROON_OSCILLATOR,
      StudyId.BOLLINGER_BANDS,
      "NEW_SMA",
  )
)

Adding favorite indicators​

Use addFavoriteStudiesByUuid to add new indicators to the favorites list without removing the existing ones.

studiesRepository.addFavoriteStudiesByUuid(
  setOf(
      StudyId.ROC,
      StudyId.ZIG_ZAG,
      "NEW_SMA",
  )
)

Removing specific favorite indicators​

Use removeFavoriteStudiesByUuid to remove specific indicators from the favorites list.

studiesRepository.removeFavoriteStudiesByUuid(
  setOf(
      StudyId.ZIG_ZAG,
      "NEW_SMA",
  )
)

Removing all favorite indicators​

Use removeAllFavoriteStudies to clear the favorites list entirely.

studiesRepository.removeAllFavoriteStudies()
