Share New Research 
Hi all,
I am relatively new to Python and trying to play around to understand how to build an algorithm.
I have a really simple question, but dont understand why I cannot figure this out.
This part:
if self.macd > 0:
self.Debug(str("macd is over 0"))
is causing me alot of headache. Why is this not working when I have a variable > 0 in the if formula? I have tried to change it from self.macd to other variables without success. but replacing the variable with a number, like numer 1 would work.
Would anyone know why and help me out with this?
Appreciate the help!
class BasicTemplateAlgorithm(QCAlgorithm):
def Initialize(self):
self.SetStartDate(2017,01,01) #Set Start Date
self.SetEndDate(2017,10,10) #Set End Date
self.SetCash(10000) #Set Strategy Cash
self.AddEquity("TSLA", Resolution.Daily)
self.smaFast = self.SMA("TSLA", 10, Resolution.Daily);
self.smaSlow = self.SMA("TSLA", 20, Resolution.Daily);
self.macd = self.MACD("TSLA", 12, 26, 9);
def OnData(self, data):
#self.Debug(str(self.macd))
if self.smaFast > self.smaSlow:
self.SetHoldings("TSLA", 1)
elif self.smaFast < self.smaSlow:
self.SetHoldings("TSLA", 0)
if self.macd > 0:
self.Debug(str("macd is over 0"))

Lean/QuantConnect indicators are not numbers, so you cannot compare an indicator object against a number.
Please use .Current.Value:
if self.macd.Current.Value > 0: self.Debug(str("macd is over 0"))Harvey Vo
Many thanks Alexandre! I was not aware of this.
Would you be able to explain how I can compare self.smaFast against self.smaSlow if they are not numbers?
Appreciate the help! It least I understand where the problem was :)

To get a number from an Indicator object, you want to use ".Current.Value" as Alex mentioned.
So the Indicator is a Class with all kinds of naughty bits inside; you just want to get the current value of that indicator for use.
if self.sma_fast.Current.Value > self.sma_slow.Current.Value:
#do stuff

Many thanks for the help. Appreciate it! :)
