Is the backtesting fully supported for IB datafeed in desktop version of Lean?

Can anybody confirm that backtesting using IB datafeed is partially supported currently in desktop version? From previous post, seems IB datafeed is not accurate or not fit Lean, is that still true? Thanks. 

Update Backtest







IB and LEAN work perfectly together. What is the previous link you're referring to?

Hi Jared,

Thanks for the quick reply. Here is the discussion link:

Also in the config.json file, there is no backtesting interactive settings. Just would like to know how should I put the settings if I would like to use IB data feed to do the backtesting? Thanks.



Best regards,

Backtesting is sourced from local data files. It would be very very slow to have backtesting sourced from IB directly. Ideally, you should use the IB Data Downloader in the toolbox to download files you need then run the backtest over them.
