Hollow candlestick chart is a mixed concept between the traditional candlestick chart and the Heikin Ashi chart with a little extra. Like the traditional candlestick chart, the pricing data for each candle are independent of the previous candle pricing; however, the candle color is rendered following the previous pricing data. Now let’s check the little extra. Candles within the Hollow candlestick chart are hollow or solid, depending on how high or low the current close price is compared to the current open price. Here is a nice summary to understand how to read the hollow candlestick charts (check the demo below):

  • Solid or Hollow
    • Solid candle if the current closing price is lower than the current opening price.
    • Hollow candle if the current closing price is higher than the current opening price
  • Green or red
    • Green candle if the current closing price is higher than the previous closing price.
    • Red candle if the current closing price is lower than the previous closing price.
