  // Description:
  // This is a specialised Price Action Channel (PAC) or Wave that mirrors the indicator used by
  // Raghee Horner, the “34EMA Wave and GRaB Candles”.
  //
  // The Wave consist of
  // – 34 period exponential moving average on the high
  // – 34 period exponential moving average on the close
  // – 34 period exponential moving average on the low
  //
  // The GRaB candles colour scheme:
  // – Lime = Bull candle closed above Wave
  // – Green = Bear candle closed above Wave
  // – Red = Bull candle closed below Wave
  // – DarkRed = Bear candle closed below Wave
  // – Aqua = Bull candle closed inside Wave
  // – Blue = Bear candle closed inside Wave
  //
  // Optionally display a trend direction indication along bottom of chart.
  //
  // Reference:
  // For some details on how Raghee uses this indicator check out
  // – https://www.forexfactory.com/showthread.php?t=492080
  // and her various training and webinar videos on Youtube
