Dealing with null data

[tomahawktom]

Hi, when i tried to run the sampletradingalgorithm package, I ran into an error. I suspect is because of 0 data that cause the compilation to stall.

File "", line 696, in _load
File "", line 677, in _load_unlocked
File "", line 728, in exec_module
File "", line 219, in _call_with_frames_removed
File "", line 102, in
"execution_count": null,
NameError: name 'null' is not defined

Hello, could you elaborate more on the problem? How do you run the package?
