Technical & Chart Analysis
Heikin-Ashi
A smoothed candle chart built from averaged values, which visualises trend more clearly but does not display real market prices.
What Heikin-Ashi means
Heikin-Ashi, meaning average bar, recalculates each candle from a blend of current and previous data. The Heikin-Ashi close is the average of the current open, high, low and close. The Heikin-Ashi open is the average of the previous Heikin-Ashi open and close. The high and low are then the extremes of the current period high or low and those two computed values. Because each candle inherits part of the one before it, noise is filtered and consecutive candles of one colour become far more common than on a standard chart.
Traders use the smoothing to stay in trends: a run of candles with no lower wick suggests uninterrupted buying, and the first candle with a wick on the opposite side or a change of colour is used as a caution or exit signal. The critical limitation, which must never be overlooked, is that Heikin-Ashi values are averages and are not prices at which anyone traded. Stops, entries and targets must always be taken from the real candlestick chart, and the smoothing also delays turns, so signals arrive late.
Worked example
A Heikin-Ashi candle on USD/JPY may print a close of 152.18 while the real close for that period was 152.34. An order placed at 152.18 because the smoothed chart showed it would misprice the trade by sixteen pips.
