Hi,
When I use LEAN CLI to do backtest, sometimes I need to access local file which includes signal. How can I do that. It seems LEAN CLI can only access the file within docker (container), not my local drive files.
Thanks,
henry

Hi Henry,
All the files in your local data directory are accessible in your algorithm. We have tutorials on how to import custom data using LEAN and on how to make it work with local files. If you only want the raw contents of a file in your data directory you can do that like this:
import os from QuantConnect import Globals path = os.path.join(Globals.DataFolder, "<path to file in data directory>") with open(path) as file: contents = file.read()Â
