Debugging backtest in Visual Studio

Hi, 

Is there way to debug a backtest in visual studio? I'm using the "Debug" tab in Lab in web. but as a developer I feel more confortable with debugging in Visual Studio. Also I'm getting this error to see the debug logs in web "You currently have a maximum of 10kb of log data per backtest, and 3072kb total max per day"

I just see these 2 options on any Algo file right click,

I could not find any instruction to debug a particular algo backtest in these links

Hey Saravana,

Could you please specify what you are trying to accomplish? Do you want to debug an algorithm running on QuantConnect's servers or debug an algorithm running locally?

Debugging backtests running on QuantConnect's servers on Visual Studios is not possible because the data for backtesting lives on QuantConnect's servers.

You could debug on Visual Studios if you are using data locally. This can be done with by either importing custom data or by using one of the data downloaders in the toolbox. But if you want to debug with QuantConnect's data, you are limited to using the debugger on the web IDE.

Best
Rahul

Hi Rahul, Thanks a lot for reply. Yes, I want to debug an algo running locally (as I feel visual studio is more user friendly).  as per your suggestion I tried Yahoodownloader in toolbox, I can able to download data in this folder. let me try local debugging.
