Introduction

Create a new Three Stars In The South candlestick pattern to indicate the pattern's presence.

Create Manual Indicators

A candlestick pattern indicator requires manual creation and update with a TradeBar object. Manual indicators let you update their values with any data you choose. The following reference table describes the ThreeStarsInSouth constructor.

ThreeStarsInSouth()1/2

            ThreeStarsInSouth QuantConnect.Indicators.CandlestickPatterns.ThreeStarsInSouth (
     string  name
   )

Initializes a new instance of the ThreeStarsInSouth class using the specified name.

ThreeStarsInSouth()2/2

            ThreeStarsInSouth QuantConnect.Indicators.CandlestickPatterns.ThreeStarsInSouth (
   )

Initializes a new instance of the ThreeStarsInSouth class.

Update Manual Indicators

You can update the indicator automatically or manually.

Automatic Update

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

using QuantConnect.Indicators.CandlestickPatterns;

private ThreeStarsInSouth _threestarsinsouth;

// In Initialize()
_threestarsinsouth = new ThreeStarsInSouth(name);
_threestarsinsouth.Updated += IndicatorUpdateMethod;

RegisterIndicator(symbol, _threestarsinsouth, Resolution.Daily);

// In IndicatorUpdateMethod()
if (_threestarsinsouth.IsReady)
{
    var indicatorValue = _threestarsinsouth.Current.Value;
}
from QuantConnect.Indicators.CandlestickPatterns import ThreeStarsInSouth
    
# In Initialize()
self.threestarsinsouth = ThreeStarsInSouth(name)
self.threestarsinsouth.Updated += self.IndicatorUpdateMethod

self.RegisterIndicator(symbol, self.threestarsinsouth, Resolution.Daily)

# In IndicatorUpdateMethod()
if self.threestarsinsouth.IsReady:
    indicator_value = self.threestarsinsouth.Current.Value

To customize the data that automatically updates the indicator, see Custom Indicator Periods and Custom Indicator Values.

Manual Update

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.

using QuantConnect.Indicators.CandlestickPatterns;
    
private ThreeStarsInSouth _threestarsinsouth;
private Symbol symbol;

// In Initialize()
_threestarsinsouth = new ThreeStarsInSouth();
symbol = AddEquity("SPY").Symbol;

// In OnData()
if (data.Bars.ContainsKey(_symbol))
{
    _threestarsinsouth.Update(data.Bars[symbol]);
}
if (_threestarsinsouth.IsReady)
{
    var indicatorValue = _threestarsinsouth.Current.Value;
}
from QuantConnect.Indicators.CandlestickPatterns import ThreeStarsInSouth
    
# In Initialize()
self.threestarsinsouth = ThreeStarsInSouth()
self.symbol = self.AddEquity("SPY").Symbol

# In OnData()
if data.Bars.ContainsKey(self.symbol):
    self.threestarsinsouth.Update(data.Bars[self.symbol])
if self.threestarsinsouth.IsReady:
    indicator_value = self.threestarsinsouth.Current.Value

Get Indicator Values

To get the value of the indicator, use its Current.Value attribute.

private ThreeStarsInSouth _threestarsinsouth;

// In Initialize()
var symbol = AddEquity("SPY").Symbol;
_threestarsinsouth = ThreeStarsInSouth(symbol);

// In OnData()
if (_threestarsinsouth.IsReady)
{
    var current = _threestarsinsouth.Current.Value;
}
# In Initialize()
symbol = self.AddEquity("SPY").Symbol
self.threestarsinsouth = self.ThreeStarsInSouth(symbol)

# In OnData()
if self.threestarsinsouth.IsReady:
    current = self.threestarsinsouth.Current.Value
