Methods

OptionalrequestBars

  • requestBars(request: IndicatorBarsRequest): Promise<readonly Bar[]>

  • The host's bar provider, when the runtime supplies one, so a fetch that needs another instrument's candles asks the host rather than carrying its own transport and credentials. Rejects when the host registered none. A request that names no variant is sent in the chart's session and adjustment (see inheritedDataVariant); naming one, {} included, wins.

    Parameters

    Returns Promise<readonly Bar[]>
