  final double highestHighQuote = _highestValueIndicator
      .getValue(index)
      .quote;
  final double lowestLowQuote = _lowestValueIndicator.getValue(index).quote;

  final double kPercent =
      ((_indicator.getValue(index).quote - lowestLowQuote) /
          (highestHighQuote - lowestLowQuote)) *
      100;

  return createResult(index: index, quote: kPercent);
