Hey Guys,  I have been having issues getting a code to work properly. So, I started from scrach and in a notebook. I have found how to call the Relative Strenght Index (RSI), Bollinger Bands, MACD, but I cannot figure out how to call the Stochastic indicator in the notebook.

I have tried, Stochastic(xxx), Sto, qb.Indicator.Sto and a number of other variants. 

I keep getting the following error:

no constructor matches given arguments
 Thoughs?qb = QuantBook()

# Parameters for Indicators
Boll_Length = 20 # Number of days back
Boll_STD = 2.1 # Standard deviation used for upper/lower bands
RSI_Lenght = 14 # Number of days taken into account
Sto_K = 10 # K lenght
Sto_D = 10 # D lenght
MACD_Fast = 12 # Fast length
MACD_Slow = 26 # Slow length
MACD_Signal = 9 # Signal lenght

# Add Equity
spy = qb.AddEquity("SPY", Resolution.Daily).Symbol

# Relative Strength Index (RSI)
rsi = RelativeStrengthIndex(RSI_Lenght)
# Bollinger Band
BollBand = BollingerBands(Boll_Length, Boll_STD, MovingAverageType.Exponential)
# Stochastic
Stoch = Stochastic(Sto_K, Sto_D)
#Stoch = qb.Indicator(STO(Sto_K, Sto_D))
# Moving Average Convergence Divergence (MACD)
Macd = MovingAverageConvergenceDivergence(MACD_Fast, MACD_Slow, MACD_Signal, MovingAverageType.Exponential)

# Create Monthly calendar consolidator
MonthlyConsolidator = TradeBarConsolidator(Calendar.Monthly)

# Define DataConsolidated event handler to track RSI values
def OnMonthlyData(sender, updated):
if rsi.IsReady:
print(f"{updated.Time} RSI VALUE: {rsi.Current.Value}")
if BollBand.IsReady:
print(f"{updated.Time} Bollinger Band: {BollBand.UpperBand}")
MonthlyConsolidator.DataConsolidated += OnMonthlyData

# Register rsi to Monthly consolidator
qb.RegisterIndicator(spy, rsi, MonthlyConsolidator)
qb.RegisterIndicator(spy, BollBand, MonthlyConsolidator)
qb.RegisterIndicator(spy, Stoch, MonthlyConsolidator)
qb.RegisterIndicator(spy, Macd, MonthlyConsolidator)

# Make history call to update consolidator, 1800 days guarantees at least 14 weeks of data
history = qb.History(spy, 1800, Resolution.Daily)
opens = history.loc["SPY"]["open"]
closes = history.loc["SPY"]["close"]
lows = history.loc["SPY"]["low"]
highs = history.loc["SPY"]["high"]
volumes = history.loc["SPY"]["volume"]
times = history.unstack(0).index.values

# Update consolidator with historical data
for i in range(len(history)):
bar = TradeBar(times[i], spy, opens[i], highs[i], lows[i], closes[i], volumes[i])
MonthlyConsolidator.Update(bar)
