Candlestick Patterns
Three Outside
Introduction
Create a new Three Outside Up/Down candlestick pattern to indicate the pattern's presence.
To view the implementation of this candlestick pattern, see the LEAN GitHub repository.
Using ThreeOutside Indicator
To create an automatic indicators for ThreeOutside
, call the ThreeOutside
helper method from the QCAlgorithm
class. The ThreeOutside
method creates a ThreeOutside
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 ThreeOutsideAlgorithm : QCAlgorithm { private Symbol _symbol; private ThreeOutside _threeoutside; public override void Initialize() { _symbol = AddEquity("SPY", Resolution.Daily).Symbol; _threeoutside = CandlestickPatterns.ThreeOutside(_symbol); } public override void OnData(Slice data) { if (_threeoutside.IsReady) { // The current value of _threeoutside is represented by itself (_threeoutside) // or _threeoutside.Current.Value Plot("ThreeOutside", "threeoutside", _threeoutside); } } }
class ThreeOutsideAlgorithm(QCAlgorithm): def Initialize(self) -> None: self.symbol = self.AddEquity("SPY", Resolution.Daily).Symbol self.threeoutside = self.CandlestickPatterns.ThreeOutside(self.symbol) def OnData(self, slice: Slice) -> None: if self.threeoutside.IsReady: # The current value of self.threeoutside is represented by self.threeoutside.Current.Value self.Plot("ThreeOutside", "threeoutside", self.threeoutside.Current.Value)
The following reference table describes the ThreeOutside
method:
ThreeOutside()1/1
ThreeOutside QuantConnect.Algorithm.CandlestickPatterns.ThreeOutside (Symbol
symbol,*Nullable<Resolution>
resolution,*Func<IBaseData, TradeBar>
selector )
Creates a new ThreeOutside
pattern indicator. 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 ThreeOutside
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 ThreeOutsideAlgorithm : QCAlgorithm { private Symbol _symbol; private ThreeOutside _threeoutside; public override void Initialize() { _symbol = AddEquity("SPY", Resolution.Daily).Symbol; _threeoutside = new ThreeOutside(); } public override void OnData(Slice data) { if (data.Bars.TryGeValue(_symbol, out var bar)) { _threeoutside.Update(bar); } if (_threeoutside.IsReady) { // The current value of _threeoutside is represented by itself (_threeoutside) // or _threeoutside.Current.Value Plot("ThreeOutside", "threeoutside", _threeoutside); } } }
class ThreeOutsideAlgorithm(QCAlgorithm): def Initialize(self) -> None: self.symbol = self.AddEquity("SPY", Resolution.Daily).Symbol self.threeoutside = ThreeOutside() def OnData(self, slice: Slice) -> None: bar = slice.Bars.get(self.symbol) if bar: self.threeoutside.Update(bar) if self.threeoutside.IsReady: # The current value of self.threeoutside is represented by self.threeoutside.Current.Value self.Plot("ThreeOutside", "threeoutside", self.threeoutside.Current.Value)
To register a manual indicator for automatic updates with the security data, call the RegisterIndicator
method.
public class ThreeOutsideAlgorithm : QCAlgorithm { private Symbol _symbol; private ThreeOutside _threeoutside; public override void Initialize() { _symbol = AddEquity("SPY", Resolution.Daily).Symbol; _threeoutside = new ThreeOutside(); RegisterIndicator(_symbol, _threeoutside, Resolution.Daily); } public override void OnData(Slice data) { if (_threeoutside.IsReady) { // The current value of _threeoutside is represented by itself (_threeoutside) // or _threeoutside.Current.Value Plot("ThreeOutside", "threeoutside", _threeoutside); } } }
class ThreeOutsideAlgorithm(QCAlgorithm): def Initialize(self) -> None: self.symbol = self.AddEquity("SPY", Resolution.Daily).Symbol self.threeoutside = ThreeOutside() self.RegisterIndicator(self.symbol, self.threeoutside, Resolution.Daily) def OnData(self, slice: Slice) -> None: if self.threeoutside.IsReady: # The current value of self.threeoutside is represented by self.threeoutside.Current.Value self.Plot("ThreeOutside", "threeoutside", self.threeoutside.Current.Value)
The following reference table describes the ThreeOutside
constructor:
ThreeOutside()1/2
ThreeOutside QuantConnect.Indicators.CandlestickPatterns.ThreeOutside (
string
name
)
Initializes a new instance of the ThreeOutside
class using the specified name.
ThreeOutside()2/2
ThreeOutside QuantConnect.Indicators.CandlestickPatterns.ThreeOutside ( )
