I'm having issues trying to get the price that I bought  for the stock. I'm trying to use 

self.Portfolio[self.syl].Price

but the price is a function that gives me the current price and not the price I bought the stock at.

I want to set a stop loss like a 10% or so. (Purchase Price * tolerance)

Is there an easy way to find the purchase price?

 

Thanks in advance!
