Heikin Ashi Smoothed Pine Script — Complete TradingView Guide

The Heikin Ashi Smoothed (HAS) indicator is a trend-following overlay for TradingView that applies triple EMA smoothing to Heikin Ashi price data, producing two crossover lines that identify trend direction with reduced noise. Built using Pine Script v6, it outputs a fast line based on hlc3 and a slow line based on ohlc4, each processed through three cascaded exponential moving averages. When the fast line crosses above the slow line, the indicator fires a buy signal; a crossunder fires a sell signal. The default smoothing length is 55 bars, making it optimal for 4H and daily swing trading on stocks, crypto, and forex. This complete guide covers the HAS formula, parameter tuning, trading strategies, and how to generate the full Pine Script code using Pineify in under two minutes.

What Is the Heikin Ashi Smoothed Indicator?

The Heikin Ashi Smoothed (HAS) indicator is a trend-following overlay that transforms raw OHLC price data into triple-smoothed lines using cascaded EMA calculations on Heikin Ashi values, used to identify trend direction and generate crossover-based entry and exit signals.

The indicator was developed as an enhancement to the standard Heikin Ashi charting technique, which was originally conceived by Munehisa Homma in 18th-century Japan as a way to visualise price momentum. The "smoothed" variant extends this concept by applying modern exponential moving average mathematics — specifically a Triple Moving Average (TMA) construction — to filter out the remaining noise in Heikin Ashi values.

Core Formula

The HAS algorithm operates in two parallel tracks:

  1. Slow line (kirmizi) — derived from ohlc4 (average of open, high, low, close). A synthetic Heikin Ashi close is computed as haC = (ohlc4 + haOpen + max(high, haOpen) + min(low, haOpen)) / 4, then three EMA passes produce TMA1. Two more triple EMA passes produce TMA2. The slow line equals TMA1 + (TMA1 − TMA2), doubling the de-lagging correction.
  2. Fast line (mavi) — the same three-pass TMA construction is applied to hlc3 (average of high, low, close) instead of the synthetic Heikin Ashi close, making it more responsive to price swings.

The variable names originate from Turkish: mavi means "blue" and kirmizi means "red", reflecting the original colour scheme of the two lines.

Applicable Markets and Timeframes

Heikin Ashi Smoothed works on all liquid markets: crypto (BTC, ETH, SOL), forex major pairs (EUR/USD, GBP/USD, USD/JPY), equity indices (SPX, NDX, DAX), and futures (ES, NQ, CL). It performs poorly on illiquid assets with large bid-ask spreads. Best timeframes are 4H, Daily, and Weekly. On shorter timeframes (1-minute to 15-minute), the triple EMA smoothing introduces lag that makes signals arrive too late for scalping purposes. The default length of 55 bars is calibrated for the Daily chart; scale it down to 21 for 4H and 13 for 1H.

Pine Script Code Example

The code below implements the complete Heikin Ashi Smoothed indicator in Pine Script v6. Copy the entire script, open the TradingView Pine Script Editor (click Pine Script Editor at the bottom of your chart), paste the code, and click Add to chart. The indicator overlays two lines directly on the price chart and calculates buy/sell crossover signals automatically.

Parameters

The Heikin Ashi Smoothed indicator has one configurable parameter that controls the smoothing intensity for both lines.

ParameterDefault ValueDescriptionRecommended Range
length55EMA smoothing period applied to both the fast (hlc3) and slow (ohlc4 / Heikin Ashi) lines. All 12 internal EMA layers use this same value.8–144
Tuning Scenarios:
  • Scalping (5m–15m charts): Use length = 8–14. Signals are frequent and responsive but may produce more false entries in ranging conditions.
  • Swing trading (4H–Daily charts): Use length = 21–55 (default 55). The Fibonacci value 55 is the classic setting, balancing lag reduction and noise filtering.
  • Position trading (Weekly chart): Use length = 89–144. Signals are rare but align with major trend changes, reducing whipsaws to near zero.

Trading Strategies

Three named strategies demonstrate how to use Heikin Ashi Smoothed crossovers in practice. Each strategy specifies exact entry and exit conditions with numbered steps.

Strategy 1: Classic HAS Crossover Trend Follow

Market environment: Trending (bullish or bearish)

The classic Heikin Ashi Smoothed crossover strategy enters in the direction of the crossover signal and rides the trend until the opposite crossover fires. Pair with **20-period SMA** to confirm trend direction before entry.

Long Entry Conditions:

  1. Fast HAS line (red) crosses above slow HAS line (blue) — buySignal == true
  2. Closing price is above the 20-bar Simple Moving Average (price in uptrend)
  3. Enter at the close of the signal bar

Exit Conditions:

  1. Fast HAS line crosses below slow HAS line — sellSignal == true
  2. Or price closes below the 20-bar SMA, confirming trend reversal

Strategy 2: HAS + RSI Filtered Swing Trade

Market environment: Trending with pullbacks

This strategy adds a **14-period RSI** filter to the HAS crossover to avoid buying into overbought conditions or selling into oversold conditions, reducing false signals on the 4H chart.

Long Entry Conditions:

  1. HAS fast line crosses above slow line — buySignal == true
  2. RSI (14) is below 70 — not overbought at entry
  3. RSI is rising (current RSI > previous bar RSI)
  4. Enter at next bar open to avoid signal-bar slippage

Exit Conditions:

  1. HAS sell signal fires — sellSignal == true
  2. Or RSI crosses above 80 (extreme overbought), take profit regardless of HAS

Strategy 3: HAS Breakout with Volume Confirmation

Market environment: Breakout from consolidation

This strategy waits for a HAS crossover that coincides with a volume spike, confirming institutional participation. Use it on the Daily chart for crypto and equity breakout setups. Pair with **20-bar average volume**.

Long Entry Conditions:

  1. HAS fast line crosses above slow line — buySignal == true
  2. Current bar volume is greater than 1.5× the 20-bar average volume
  3. Both HAS lines are sloping upward (fast line value > fast line value 3 bars ago)
  4. Enter at market close of signal bar

Exit Conditions:

  1. HAS sell signal fires — sellSignal == true
  2. Or a 2× ATR trailing stop is hit below the most recent swing low
