Mid Point

Introduction

This indicator computes the MidPoint (MIDPOINT) The MidPoint is calculated using the following formula: MIDPOINT = (Highest Value + Lowest Value) / 2

Using MIDPOINT Indicator

To create an automatic indicators for MidPoint, call the MIDPOINT helper method from the QCAlgorithm class. The MIDPOINT method creates a MidPoint 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 MidPointAlgorithm : QCAlgorithm
{
    private Symbol _symbol;
    private MidPoint _midpoint;

    public override void Initialize()
    {
        _symbol = AddEquity("SPY", Resolution.Daily).Symbol;
        _midpoint = MIDPOINT("SPY", 20);
    }

    public override void OnData(Slice data)
    {
        if (_midpoint.IsReady)
        {
            Plot("MidPoint", "midpoint", _midpoint);
        }
    }
}
class MidPointAlgorithm(QCAlgorithm):
    def Initialize(self) -> None:
        self.symbol = self.AddEquity("SPY", Resolution.Daily).Symbol
        self.midpoint = self.MIDPOINT("SPY", 20)

    def OnData(self, slice: Slice) -> None:
        if self.midpoint.IsReady:
            self.Plot("MidPoint", "midpoint", self.midpoint.Current.Value)

The following reference table describes the MIDPOINT method:

MIDPOINT()1/1

            MidPoint QuantConnect.Algorithm.QCAlgorithm.MIDPOINT (
    Symbol                           symbol,
    Int32                            period,
    *Nullable<Resolution>      resolution,
    *Func<IBaseData, Decimal>  selector
   )

Creates a new MidPoint indicator.

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.

For more information about plotting indicators, see Plotting Indicators.

You can manually create a MidPoint 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 time/number pair, or an IndicatorDataPoint. The indicator will only be ready after you prime it with enough data.

public class MidPointAlgorithm : QCAlgorithm
{
    private Symbol _symbol;
    private MidPoint _midpoint;

    public override void Initialize()
    {
        _symbol = AddEquity("SPY", Resolution.Daily).Symbol;
        _midpoint = new MidPoint(20);
    }

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

        if (_midpoint.IsReady)
        {
            Plot("MidPoint", "midpoint", _midpoint);
        }
    }
}
class MidPointAlgorithm(QCAlgorithm):
    def Initialize(self) -> None:
        self.symbol = self.AddEquity("SPY", Resolution.Daily).Symbol
        self.midpoint = MidPoint(20)

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

        if self.midpoint.IsReady:
            self.Plot("MidPoint", "midpoint", self.midpoint.Current.Value)

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

public class MidPointAlgorithm : QCAlgorithm
{
    private Symbol _symbol;
    private MidPoint _midpoint;

    public override void Initialize()
    {
        _symbol = AddEquity("SPY", Resolution.Daily).Symbol;
        _midpoint = new MidPoint(20);
        RegisterIndicator(_symbol, _midpoint, Resolution.Daily);
    }

    public override void OnData(Slice data)
    {
        if (_midpoint.IsReady)
        {
            Plot("MidPoint", "midpoint", _midpoint);
        }
    }
}
class MidPointAlgorithm(QCAlgorithm):
    def Initialize(self) -> None:
        self.symbol = self.AddEquity("SPY", Resolution.Daily).Symbol
        self.midpoint = MidPoint(20)
        self.RegisterIndicator(self.symbol, self.midpoint, Resolution.Daily)

    def OnData(self, slice: Slice) -> None:
        if self.midpoint.IsReady:
            self.Plot("MidPoint", "midpoint", self.midpoint.Current.Value)

The following reference table describes the MidPoint constructor:

MidPoint()1/2

            MidPoint QuantConnect.Indicators.MidPoint (
    string  name,
    int     period
   )

Initializes a new instance of the MidPoin class using the specified name and period.

MidPoint()2/2

            MidPoint QuantConnect.Indicators.MidPoint (
    int  period
   )

Initializes a new instance of the MidPoin class using the specified period.
