Average Directional Movement Index Rating
Introduction
This indicator computes the Average Directional Movement Index Rating (ADXR). The Average Directional Movement Index Rating is calculated with the following formula: ADXR[i] = (ADX[i] + ADX[i - period + 1]) / 2
To view the implementation of this indicator, see the LEAN GitHub repository.
Using ADXR Indicator
To create an automatic indicator for AverageDirectionalMovementIndexRating, call the ADXRadxr helper method from the QCAlgorithm class. The ADXRadxr method creates a AverageDirectionalMovementIndexRating 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 AverageDirectionalMovementIndexRatingAlgorithm : QCAlgorithm
{
private Symbol _symbol;
private AverageDirectionalMovementIndexRating _adxr;
public override void Initialize()
{
_symbol = AddEquity("SPY", Resolution.Daily).Symbol;
_adxr = ADXR(_symbol, 20);
}
public override void OnData(Slice data)
{
if (_adxr.IsReady)
{
// The current value of _adxr is represented by itself (_adxr)
// or _adxr.Current.Value
Plot("AverageDirectionalMovementIndexRating", "adxr", _adxr);
// Plot all properties of abands
Plot("AverageDirectionalMovementIndexRating", "adx", _adxr.ADX);
}
}
} class AverageDirectionalMovementIndexRatingAlgorithm(QCAlgorithm):
def initialize(self) -> None:
self._symbol = self.add_equity("SPY", Resolution.DAILY).symbol
self._adxr = self.adxr(self._symbol, 20)
def on_data(self, slice: Slice) -> None:
if self._adxr.is_ready:
# The current value of self._adxr is represented by self._adxr.current.value
self.plot("AverageDirectionalMovementIndexRating", "adxr", self._adxr.current.value)
# Plot all attributes of self._adxr
self.plot("AverageDirectionalMovementIndexRating", "adx", self._adxr.adx.current.value)For more information about this method, see the QCAlgorithm classQCAlgorithm class.
You can manually create a AverageDirectionalMovementIndexRating 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.

{
private Symbol _symbol;
private AverageDirectionalMovementIndexRating _averagedirectionalmovementindexrating;
public override void Initialize()
{
_symbol = AddEquity("SPY", Resolution.Daily).Symbol;
_averagedirectionalmovementindexrating = new AverageDirectionalMovementIndexRating(20);
}
public override void OnData(Slice data)
{
if (data.Bars.TryGetValue(_symbol, out var bar))
_averagedirectionalmovementindexrating.Update(bar);
if (_averagedirectionalmovementindexrating.IsReady)
{
// The current value of _averagedirectionalmovementindexrating is represented by itself (_averagedirectionalmovementindexrating)
// or _averagedirectionalmovementindexrating.Current.Value
Plot("AverageDirectionalMovementIndexRating", "averagedirectionalmovementindexrating", _averagedirectionalmovementindexrating);
// Plot all properties of abands
Plot("AverageDirectionalMovementIndexRating", "adx", _averagedirectionalmovementindexrating.ADX);
}
}

self._symbol = self.add_equity("SPY", Resolution.DAILY).symbol
self._averagedirectionalmovementindexrating = AverageDirectionalMovementIndexRating(20)
def on_data(self, slice: Slice) -> None:
bar = slice.bars.get(self._symbol)
if bar:
self._averagedirectionalmovementindexrating.update(bar)
if self._averagedirectionalmovementindexrating.is_ready:
# The current value of self._averagedirectionalmovementindexrating is represented by self._averagedirectionalmovementindexrating.current.value
self.plot("AverageDirectionalMovementIndexRating", "averagedirectionalmovementindexrating", self._averagedirectionalmovementindexrating.current.value)
# Plot all attributes of self._averagedirectionalmovementindexrating

Indicator History
To get the historical data of the AverageDirectionalMovementIndexRating 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.
