Hello everyone! I'm new to QuantConnect/Lean. I have a few questions...
- If I subscribe to the Prime service, can I utilize the subscription datafeed and make trades from Lean (localpc)?
- Is it possible to make external( to quantconnect.com ) REST API calls from the hosted QuantConnect service? Both during backtest and live trading.
- When backtesting with Lean(local PC) using my own data provider, does Lean request the data from provider every backtest or does it load via a cache for data it has already requested in the past? If I run multiple backtests for the same instrument/period it would be much faster to load the data from a cache vs provider.
- Does a QuantConnect backtest leverage processing power across multiple cloud machines (distributed) or parallel on a single multicore machine?
- Is there a link that shows me a comprehensive list of features for QuantConnect/Lean. And maybe a comparison of both.
Thanks!

One more. Is it possbile to write and debug algorithims in Python in Visual Studio/Lean?

Also, when live trading on desktop (Lean) what is the dependancy on quantconnect.com for entering in the "job-user-id" and "api-access-token"? Shouldn't the only thing needed be broker specific id and password (e.g, "ib-account", "ib-user-name", "ib-password")?

Hey ChristopherD! Welcome to QuantConnect.
- Local backtests can only utilitize local data due to licensing restrictions; unless you've purchased or have the data in your QuantConnect data library (quantconnect.com/data).
- Local backtests use your computer. QuantConnect's run in a cloud environment but are running on a single machine. Optimization (coming soon) runs on multiple machines.
- QuantConnect runs on LEAN, so the feature list is identical. The exception is the data is provided for you on QuantConnect.
- Yes its possible to use Python anywhere in QC -- check out the QuantConnect.Python project in LEAN.
- API Access token etc is used for local charting -- if you want to have a desktop charting environment while you work.

Thanks Jared.
If I run a strategy on quantconnect cloud can my code make REST calls to an external AWS hosted server?
ChristopherD
Bump ^. I have one more question in my post above... :)

Sorry Chrisopher missed that; yes you can make rest calls in live mode.
