Heikin Ashi

Introduction

This indicator computes the Heikin-Ashi bar (HA) The Heikin-Ashi bar is calculated using the following formulas: HA_Close[0] = (Open[0] + High[0] + Low[0] + Close[0]) / 4 HA_Open[0] = (HA_Open[1] + HA_Close[1]) / 2 HA_High[0] = MAX(High[0], HA_Open[0], HA_Close[0]) HA_Low[0] = MIN(Low[0], HA_Open[0], HA_Close[0])

Using HeikinAshi Indicator

To create an automatic indicators for HeikinAshi, call the HeikinAshi helper method from the QCAlgorithm class. The HeikinAshi method creates a HeikinAshi object, hooks it up for automatic updates, and returns it so you can used it in your algorithm. In most cases, you should call the helper method in the Initialize method.

public class HeikinAshiAlgorithm : QCAlgorithm
{
    private Symbol _symbol;
    private HeikinAshi _heikinashi;

    public override void Initialize()
    {
        _symbol = AddEquity("SPY", Resolution.Daily).Symbol;
        _heikinashi = HeikinAshi("SPY");
    }

    public override void OnData(Slice data)
    {
        if (_heikinashi.IsReady)
        {
            Plot("HeikinAshi", "heikinashi", _heikinashi);
            Plot("HeikinAshi", "open", _heikinashi.Open);
            Plot("HeikinAshi", "high", _heikinashi.High);
            Plot("HeikinAshi", "low", _heikinashi.Low);
            Plot("HeikinAshi", "close", _heikinashi.Close);
            Plot("HeikinAshi", "volume", _heikinashi.Volume);
        }
    }
}
class HeikinAshiAlgorithm(QCAlgorithm):
    def Initialize(self) -> None:
        self.symbol = self.AddEquity("SPY", Resolution.Daily).Symbol
        self.heikinashi = self.HeikinAshi("SPY")

    def OnData(self, slice: Slice) -> None:
        if self.heikinashi.IsReady:
            self.Plot("HeikinAshi", "heikinashi", self.heikinashi.Current.Value)
            self.Plot("HeikinAshi", "open", self.heikinashi.Open.Current.Value)
            self.Plot("HeikinAshi", "high", self.heikinashi.High.Current.Value)
            self.Plot("HeikinAshi", "low", self.heikinashi.Low.Current.Value)
            self.Plot("HeikinAshi", "close", self.heikinashi.Close.Current.Value)
            self.Plot("HeikinAshi", "volume", self.heikinashi.Volume.Current.Value)

If you don't provide a resolution, it defaults to the security resolution. If you provide a resolution, it must be greater than or equal to the resolution of the security. For instance, if you subscribe to hourly data for a security, you should update its indicator with data that spans 1 hour or longer.

For more information about the selector argument, see Alternative Price Fields.

You can manually create a HeikinAshi indicator, so it doesn't automatically update. Manual indicators let you update their values with any data you choose.

Updating your indicator manually enables you to control when the indicator is updated and what data you use to update it. To manually update the indicator, call the Update method with a TradeBar, or QuoteBar. The indicator will only be ready after you prime it with enough data.

public class HeikinAshiAlgorithm : QCAlgorithm
{
    private Symbol _symbol;
    private HeikinAshi _heikinashi;

    public override void Initialize()
    {
        _symbol = AddEquity("SPY", Resolution.Daily).Symbol;
        _heikinashi = new HeikinAshi("SPY");
    }

    public override void OnData(Slice data)
    {
        if (data.Bars.TryGeValue(_symbol, out var bar))
        {      
            _heikinashi.Update(bar);
        }

        if (_heikinashi.IsReady)
        {
            Plot("HeikinAshi", "heikinashi", _heikinashi);
            Plot("HeikinAshi", "open", _heikinashi.Open);
            Plot("HeikinAshi", "high", _heikinashi.High);
            Plot("HeikinAshi", "low", _heikinashi.Low);
            Plot("HeikinAshi", "close", _heikinashi.Close);
            Plot("HeikinAshi", "volume", _heikinashi.Volume);
        }
    }
}
class HeikinAshiAlgorithm(QCAlgorithm):
    def Initialize(self) -> None:
        self.symbol = self.AddEquity("SPY", Resolution.Daily).Symbol
        self.heikinashi = HeikinAshi("SPY")

    def OnData(self, slice: Slice) -> None:
        bar = data.Bars.get(self.symbol)
        if bar:
            self.heikinashi.Update(bar)

        if self.heikinashi.IsReady:
            self.Plot("HeikinAshi", "heikinashi", self.heikinashi.Current.Value)
            self.Plot("HeikinAshi", "open", self.heikinashi.Open.Current.Value)
            self.Plot("HeikinAshi", "high", self.heikinashi.High.Current.Value)
            self.Plot("HeikinAshi", "low", self.heikinashi.Low.Current.Value)

            self.Plot("HeikinAshi", "volume", self.heikinashi.Volume.Current.Value)

To register a manual indicator for automatic updates with the security data, call the RegisterIndicator method.

public class HeikinAshiAlgorithm : QCAlgorithm
{
    private Symbol _symbol;
    private HeikinAshi _heikinashi;

    public override void Initialize()
    {
        _symbol = AddEquity("SPY", Resolution.Daily).Symbol;
        _heikinashi = new HeikinAshi("SPY");
        RegisterIndicator(_symbol, _heikinashi, Resolution.Daily);
    }

    public override void OnData(Slice data)
    {
        if (_heikinashi.IsReady)
        {
            Plot("HeikinAshi", "heikinashi", _heikinashi);
            Plot("HeikinAshi", "open", _heikinashi.Open);
            Plot("HeikinAshi", "high", _heikinashi.High);
            Plot("HeikinAshi", "low", _heikinashi.Low);
            Plot("HeikinAshi", "close", _heikinashi.Close);
            Plot("HeikinAshi", "volume", _heikinashi.Volume);
        }
    }
}
class HeikinAshiAlgorithm(QCAlgorithm):
    def Initialize(self) -> None:
        self.symbol = self.AddEquity("SPY", Resolution.Daily).Symbol
        self.heikinashi = HeikinAshi("SPY")
        self.RegisterIndicator(self.symbol, self.heikinashi, Resolution.Daily)

    def OnData(self, slice: Slice) -> None:
        if self.heikinashi.IsReady:
            self.Plot("HeikinAshi", "heikinashi", self.heikinashi.Current.Value)
            self.Plot("HeikinAshi", "open", self.heikinashi.Open.Current.Value)
            self.Plot("HeikinAshi", "high", self.heikinashi.High.Current.Value)
            self.Plot("HeikinAshi", "low", self.heikinashi.Low.Current.Value)
            self.Plot("HeikinAshi", "close", self.heikinashi.Close.Current.Value)
