Hi Apollos.
Thank you for pointing out the error you encountered. I have fixed the bug that caused the strategy to break down. The error was caused because scalar was being passed to the function regr.predict(), instead of a 2d array. You can now access the fixed WTI/Brent Spread strategy in the Strategy Library and in the attached backtest.

Thanks Halldor!
