Hey, I just wanted to say thanks in advance for the optimization. This is a valuable and fun addition to Quantconnect. I have an algo that compares a value to a number. Lets say the number is 15. If a slope of a line is < or > 15 then it would signal a trade. I would like to set up the code to run an optimization on the number 15.
I tried to add:
def Initialize(self):
self.GoShort = self.GetParameter("QQQShort")
And then on Ondata I used:
"self.GoShort.Current.Value" to try to have the optomizer fill in units into the single digit (in replace of the 15).
However, this is not working. The backtests all fail.
TypeError : '<' not supported between instances of 'float' and 'NoneType'
at OnData in main.py:
For the line with "self.GoShort.Current.Value"
Any thoughts?

Hi David,
The GetParameter method returns a string. Instead of calling `.Current.Value`, cast the value returned to an integer.
See the attached backtest for reference.
Best,
Derek Melchin
