It can be actually project of any type. The plugin simply adds to it files from QuantConnect cloud. - Connect local project to cloud project.
- Add to the project algorithm files, as described here:
https://www.quantconnect.com/docs/REST#Developing-in-the-IDE
All files uploaded to cloud must inherit from QCAlgorithm base type:public partial class BasicTemplateAlgorithm : QCAlgorithm, IAlgorithm {...}
The sample algorithm templates are available here: https://github.com/QuantConnect/Lean/tree/master/Algorithm.CSharp - Create backtest by Building Project.
- Double click on some project or select a project and do Refresh backtests.
- Select backtest and do Load Backtest.
