Heikin-Ashi charts are a variation of Japanese candlestick charts that were designed to remove noise from candlesticks and behave much like a moving average. These charts can be used to identify trends, potential reversal points, and other technical analysis patterns.

While the appearance of Heikin-Ashi charts are identical to candlestick charts, the underlying price values are calculated based on the following formulas:

haHigh
  Max(high[0], haOpen[0], haClose[0])
haLow
  Min(low[0], haOpen[0], haClose[0])
haOpen
  Avg(haOpen[-1], haClose[-1])
haClose
  Avg(high[0], low[0], open[0], close[0])

"-1" indicates the previous period; "0" indicates the current period
