Ease Of Movement Value

Introduction

This indicator computes the n-period Ease of Movement Value using the following: MID = (high_1 + low_1)/2 - (high_0 + low_0)/2 RATIO = (currentVolume/10000) / (high_1 - low_1) EMV = MID/RATIO _SMA = n-period of EMV Returns _SMA source

To view the implementation of this indicator, see the LEAN GitHub repository.

Using EMV Indicator

To create an automatic indicator for EaseOfMovementValue, call the EMVemv helper method from the QCAlgorithm class. The EMVemv method creates a EaseOfMovementValue 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 Initializeinitialize method.

public class EaseOfMovementValueAlgorithm : QCAlgorithm
{
    private Symbol _symbol;
    private EaseOfMovementValue _emv;

    public override void Initialize()
    {
        _symbol = AddEquity("SPY", Resolution.Daily).Symbol;
        _emv = EMV(_symbol, 1, 10000);
    }

    public override void OnData(Slice data)
    {

        if (_emv.IsReady)
        {
            // The current value of _emv is represented by itself (_emv)
            // or _emv.Current.Value
            Plot("EaseOfMovementValue", "emv", _emv);
        }
    }
}
class EaseOfMovementValueAlgorithm(QCAlgorithm):
    def initialize(self) -> None:
        self._symbol = self.add_equity("SPY", Resolution.DAILY).symbol
        self._emv = self.emv(self._symbol, 1, 10000)

    def on_data(self, slice: Slice) -> None:

        if self._emv.is_ready:
            # The current value of self._emv is represented by self._emv.current.value
            self.plot("EaseOfMovementValue", "emv", self._emv.current.value)

For more information about this method, see the QCAlgorithm classQCAlgorithm class.

You can manually create a EaseOfMovementValue 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 Updateupdate method. The indicator will only be ready after you prime it with enough data.

public class EaseOfMovementValueAlgorithm : QCAlgorithm
{
    private Symbol _symbol;
    private EaseOfMovementValue _easeofmovementvalue;

    public override void Initialize()
    {
        _symbol = AddEquity("SPY", Resolution.Daily).Symbol;
        _easeofmovementvalue = new EaseOfMovementValue(1, 10000);
    }

    public override void OnData(Slice data)
    {
        if (data.Bars.TryGetValue(_symbol, out var bar))
            _easeofmovementvalue.Update(bar);

        if (_easeofmovementvalue.IsReady)
        {
            // The current value of _easeofmovementvalue is represented by itself (_easeofmovementvalue)
            // or _easeofmovementvalue.Current.Value
            Plot("EaseOfMovementValue", "easeofmovementvalue", _easeofmovementvalue);
        }
    }
}
class EaseOfMovementValueAlgorithm(QCAlgorithm):
    def initialize(self) -> None:
        self._symbol = self.add_equity("SPY", Resolution.DAILY).symbol
        self._easeofmovementvalue = EaseOfMovementValue(1, 10000)

    def on_data(self, slice: Slice) -> None:
        bar = slice.bars.get(self._symbol)
        if bar:
            self._easeofmovementvalue.update(bar)

        if self._easeofmovementvalue.is_ready:
            # The current value of self._easeofmovementvalue is represented by self._easeofmovementvalue.current.value
            self.plot("EaseOfMovementValue", "easeofmovementvalue", self._easeofmovementvalue.current.value)

Indicator History

To get the historical data of the EaseOfMovementValue indicator, call the IndicatorHistoryself.indicator_history method. This method resets your indicator, makes a history request, and updates the indicator with the historical data. Just like with regular history requests, the IndicatorHistoryindicator_history method supports time periods based on a trailing number of bars, a trailing period of time, or a defined period of time. If you don't provide a resolution argument, it defaults to match the resolution of the security subscription. 

public class EaseOfMovementValueAlgorithm : QCAlgorithm
{
    private Symbol _symbol;
    private EaseOfMovementValue _emv;

    public override void Initialize()
    {
        _symbol = AddEquity("SPY", Resolution.Daily).Symbol;
        _emv = EMV(_symbol, 1, 10000);

        var indicatorHistory = IndicatorHistory(_emv, _symbol, 100, Resolution.Minute);
        var timeSpanIndicatorHistory = IndicatorHistory(_emv, _symbol, TimeSpan.FromDays(10), Resolution.Minute);
        var timePeriodIndicatorHistory = IndicatorHistory(_emv, _symbol, new DateTime(2024, 7, 1), new DateTime(2024, 7, 5), Resolution.Minute);
    }
}
class EaseOfMovementValueAlgorithm(QCAlgorithm):
    def initialize(self) -> None:
        self._symbol = self.add_equity("SPY", Resolution.DAILY).symbol
        self._emv = self.emv(self._symbol, 1, 10000)

        indicator_history = self.indicator_history(self._emv, self._symbol, 100, Resolution.MINUTE)
        timedelta_indicator_history = self.indicator_history(self._emv, self._symbol, timedelta(days=10), Resolution.MINUTE)
        time_period_indicator_history = self.indicator_history(self._emv, self._symbol, datetime(2024, 7, 1), datetime(2024, 7, 5), Resolution.MINUTE)
