Heikin-AshiHA

Heikin-Ashi is a chart type whose candles are calculated from averages of current and previous prices to smooth out noise; its prices are not actual traded prices.

Regular candles flicker between colours even in a steady trend. Heikin-Ashi averages the numbers first, so trends show up as long runs of same-coloured candles — at the cost of hiding the real prices.

Heikin-Ashi in plain words

The name roughly means average pace, and it represents the average pace of prices.1

Its candles are built from averages of the current and prior period, which makes the chart smoother.2

Its open, high, low and close are not prices the asset actually traded at.2

How Heikin-Ashi candles are calculated

  1. HA close

    Average the current open, high, low and close.1

  2. HA open

    Average the prior HA open and prior HA close.1

  3. HA high

    Take the maximum of the high, HA open and HA close.1

  4. HA low

    Take the minimum of the low, HA open and HA close.1

  5. Colour the candle

    It is hollow when HA close is above HA open.1

  6. Read the trend

    Use runs of candles to identify trending periods and potential reversals.1

Worked examples

Example 1 — Computing an HA close

HA close = $101

A hypothetical day: open $100, high $104, low $98, close $102.

Example 1 — Computing an HA close — calculation
Sum$404
HA close$404 ÷ 4 = $101

The HA close is the average of open, high, low and close, so it is $101 rather than the real $102 close.1

Example 2 — Computing an HA open

HA open = $100

The prior HA candle had HA open $99 and HA close $101.

Example 2 — Computing an HA open — calculation
HA open($99 + $101) ÷ 2 = $100

The HA open averages the prior HA open and close, which is why HA candles rarely gap.1

Example 3 — The price gap problem

$2 worse entry than the chart suggests

A hypothetical HA signal says buy at $5, but the stock has gapped to $7.

Example 3 — The price gap problem — calculation
Signal price$5
Real price$7

This is the risk CMC describes: a signal at $5 while the stock already trades at $7, because HA values are not real traded prices.2
