Hello All,

I am new to QuantConnect and still figuring out the basics. I need to know how to check what stocks my algorithim is invested in at a given time.

For example, if my algo buys AAPL, I need my algo to check if it's invested in AAPL so it can act accordingly.

I tried something like this, but get "'bool' object is not callable."

if self.Portfolio.Invested('XIV'):

self.SetHoldings(self.xiv, 0)
self.SetHoldings(self.vxx, 1)
elif self.Portfolio.Invested('VXX'):

self.SetHoldings(self.xiv, 1)
self.SetHoldings(self.vxx, 0)
