Any guidance on when to use self. ?

Hi, I see some code in strategy as follows:

def __init__(self):
    # To control operation entries
    self.orderid = None

    # Create SMA on 2nd data
    sma = btind.MovAv.SMA(self.data1, period=self.p.period)
    # Create a CrossOver Signal from close an moving average
    self.signal = btind.CrossOver(self.data1.close, sma)

I wonder why the sma isn't prefixed by self. while signal is. Is there any guidance tell us when to use self or not?

When to use self is a general python coding issues and you can google or youtube it to learn it's application. If you get stuck after that let us know.
