Need help - simple question

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"))

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

1

Many thanks for the help. Appreciate it! :)
