Compare Current Price to EMA Indicator

Hello All,

I am having trouble with, what I would think, a very simple problem. I am trying to compare the current price of the TQQQ with the current value of the 50 day Exponential Moving Average (EMA50) of the TQQQ.

class BasicTemplateAlgorithm(QCAlgorithm):

def Initialize(self):
# Set the cash we'd like to use for our backtest
# This is ignored in live trading

# Start and end dates for the backtest.
# These are ignored in live trading.

# Assets predetermined
self.tqqq = self.AddEquity("TQQQ", Resolution.Daily).Symbol
# Indicators
self.emaSmaller = self.EMA("TQQQ", 50, Resolution.Daily)

def OnData(self, slice):
if not self.Portfolio.Invested:
self.Debug("Working after PortfolioInvested")

if float(self.Securities["TQQQ"].Price) > self.emaSmaller:
self.Debug("Working after first comparison")
self.SetHoldings(self.tqqq, 1)

When I compare self.Securities["TQQQ"].Price and self.emaSmaller, I get this error:

Runtime Error: Python.Runtime.PythonException: TypeError : Cannot get managed object
at (wrapper dynamic-method) System.Object:CallSite.Target (System.Runtime.CompilerServices.Closure, System.Runtime.CompilerServices.CallSite, object, QuantConnect.Data.Slice)

How do I fix this problem.



Update Backtest

Hi Malachi, 

To fix this, you should compare the two values as following:

if self.Securities["TQQQ"].Price > self.emaSmaller.Current.Value:

No need to convert self.Securities["TQQQ"].Price to float since self.Securities["TQQQ"].Price and self.emaSmaller.Current.Value are decimal types.


Worked perfectly!


Update Backtest
