Missing imports when using Skylight

Hi,

I downloaded Skylight and started using Quantconnect recently.

I want to be able to use my favorite IDE with source control when writing my algorithms.

From what I see, it's very possible with Skylight. But I am having a problem. When I try to sync the code using Skylight it only syncs the code itself without the imports.
For example name, 'QCAlgorithm' is not defined

How do I fix this?

Hi לירן ז'וק,

To fix this issue, add the following imports to the top of the script.

from clr import AddReference
AddReference("System")
AddReference("QuantConnect.Algorithm")
AddReference("QuantConnect.Common")
from System import *
from QuantConnect import *
from QuantConnect.Algorithm import *

These are all found at the top of BasicTemplateAlgorithm.py.

In general, if an import is missing, we need to find the class in Lean and add the namespace. For example:

from QuantConnect.Python import PythonData

since PythonData class is found in the QuantConnect.Python namespace.

Hi thanks for the answer!

Do I need to use Lean in order for the code to recognize the imports?

I am trying to code in VSCode and it does not seem to find the imports? In visual studio it works, any ideas?
