Heikin Ashi Signals: Synthetic Candles and Real Execution Prices

Inspect Heikin Ashi color runs, wick geometry and small bodies with a Pine Script example. Keep synthetic candle signals separate from executable market prices.

Heikin Ashi Signal Interpretation

Quick-reference guide to 5 signal types you will see on the chart.

Signal Type	Indicator Condition	Market Meaning	Interpretation limits
Two bullish no-lower-wick candles	Two consecutive HA closes exceed their HA opens, with no lower wick within tolerance	A pattern in averaged candles.	Does not establish that buyers absorbed every sell order.
Two bearish no-upper-wick candles	Two consecutive bearish HA bodies with no upper wick within tolerance	The opposite synthetic-candle pattern.	Not evidence of every intrabar order or a guaranteed decline.
Small body after two same-color candles	Current HA body/range is below a configured threshold after two bullish or bearish bodies	A change in the averaged candle geometry.	No reversal probability or imminent exhaustion is established.
Three bullish no-lower-wick candles	Three consecutive candles meet that HA definition	Persistence of the defined synthetic pattern.	Not automatically the traditional three-white-soldiers pattern.
Three bearish no-upper-wick candles	Three consecutive candles meet the opposite HA definition	A corresponding persistence condition.	No expected price move, return or reliability score is claimed.

Example settings for Heikin Ashi

Record the inputs used by the example. These settings are not an optimized trading recommendation.

Feature comparison table: Default vs Description
Parameter	Default	Description
Small Body Ratio	0.15, example	A body smaller than 15% of its synthetic range meets this definition. Zero-range bars are excluded.
Data source	TradingView Heikin Ashi ticker	Uses the documented ticker.heikinashi request. It does not incorrectly calculate HA open from only the previous ordinary candle.
Wick tolerance	0.01 minimum tick	Numerical equality allowance, not a tradeable minimum price increment or an optimized pattern tolerance.
Chart context	Standard time-based candles	Run the example on standard bars and compare synthetic overlay values separately. No additional smoothing input is supplied or claimed.

FAQ

Heikin Ashi Signals FAQ

What is wrong with using the prior regular candle for HA open?

The recursive HA open depends on the previous HA open and close. Replacing those with the previous ordinary open and close produces another calculation. This example requests TradingView’s HA series rather than presenting that approximation as standard HA.

Can I trade at the displayed Heikin Ashi close?

It is a synthetic average, not necessarily an executable price. Keep signal calculation separate from fills. TradingView documents standard-OHLC fills for strategies on HA charts; even then costs and execution assumptions matter.

Does a missing wick prove order-flow absorption?

No. The wick follows from the synthetic open, close, high and low calculation. It does not identify who traded or reconstruct every intrabar attempt to buy or sell.

Do these candles never change?

The developing candle can change with current data. The example confirms markers at chart-bar close and requests the same timeframe without lookahead. That is a specific timing choice, not a certification of every custom HA script.

Is more smoothing always better?

It changes the representation and can delay or remove events. The example uses standard HA without an extra smoothing parameter; no personal test or improvement percentage is asserted.

How can I evaluate a pattern?

Compare the requested OHLC with TradingView HA candles using the same symbol, session and timeframe. Verify each wick/body condition, then evaluate any strategy on real-price execution assumptions. A pattern count alone is not a win rate.
