Supported Indicators
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 indicators for EaseOfMovementValue, call the EMV helper method from the QCAlgorithm class. The EMV 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 Initialize 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.AddEquity("SPY", Resolution.Daily).Symbol
self.emv = self.EMV(self.symbol, 1, 10000)
def OnData(self, slice: Slice) -> None:
if self.emv.IsReady:
# The current value of self.emv is represented by self.emv.Current.Value
self.Plot("EaseOfMovementValue", "emv", self.emv.Current.Value)
The following reference table describes the EMV method:
EMV()1/1
EaseOfMovementValue QuantConnect.Algorithm.QCAlgorithm.EMV (
Symbol symbol,
*Int32 period,
*Int32 scale,
*Nullable<Resolution> resolution,
*Func<IBaseData, TradeBar> selector
)
Creates an EaseOfMovementValue indicator for the symbol. The indicator will be automatically updated on the given resolution.
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 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 Update method with a TradeBar. The indicator will only be ready after you prime it with enough data.
public class EaseOfMovementValueAlgorithm : QCAlgorithm
{
private Symbol _symbol;
private EaseOfMovementValue _emv;
public override void Initialize()
{
_symbol = AddEquity("SPY", Resolution.Daily).Symbol;
_emv = new EaseOfMovementValue(1, 10000);
}
public override void OnData(Slice data)
{
if (data.Bars.TryGeValue(_symbol, out var bar))
{
_emv.Update(bar);
}
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.AddEquity("SPY", Resolution.Daily).Symbol
self.emv = EaseOfMovementValue(1, 10000)
def OnData(self, slice: Slice) -> None:
bar = slice.Bars.get(self.symbol)
if bar:
self.emv.Update(bar)
if self.emv.IsReady:
# The current value of self.emv is represented by self.emv.Current.Value
self.Plot("EaseOfMovementValue", "emv", self.emv.Current.Value)
To register a manual indicator for automatic updates with the security data, call the RegisterIndicator method.
public class EaseOfMovementValueAlgorithm : QCAlgorithm
{
private Symbol _symbol;
private EaseOfMovementValue _emv;
public override void Initialize()
{
_symbol = AddEquity("SPY", Resolution.Daily).Symbol;
_emv = new EaseOfMovementValue(1, 10000);
RegisterIndicator(_symbol, _emv, Resolution.Daily);
}
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.AddEquity("SPY", Resolution.Daily).Symbol
self.emv = EaseOfMovementValue(1, 10000)
self.RegisterIndicator(self.symbol, self.emv, Resolution.Daily)
def OnData(self, slice: Slice) -> None:
if self.emv.IsReady:
# The current value of self.emv is represented by self.emv.Current.Value
self.Plot("EaseOfMovementValue", "emv", self.emv.Current.Value)
The following reference table describes the EaseOfMovementValue constructor:
EaseOfMovementValue()1/2
EaseOfMovementValue QuantConnect.Indicators.EaseOfMovementValue (
*int period,
*int scale
)
Initializeds a new instance of the EaseOfMovement class using the specufued period.
EaseOfMovementValue()2/2
EaseOfMovementValue QuantConnect.Indicators.EaseOfMovementValue (
string name,
int period,
int scale
)
Creates a new EaseOfMovement indicator with the specified period.
