QUANTCONNECT COMMUNITY
Hello, I have recently begun working on my algorithms again after a break and I am getting the following error every time i try to run a backtest:
RollingWindow must have size of at least 1. (Parameter 'size') in RollingWindow.cs:line 52
I am not using a rolling window in my strategy and it is happening in every algorithm I try to run. Did something change that I am not aware of?
Thank you, I have attached a backtest showing the error occurring.
