I see that QC/Lean supports Bloomberg both for data and for trading, but I'm a little confused on the requirements and cost.
- I have a Bloomberg Anywhere account, so can I use the Bloomberg Desktop API for market data to perform backtests by just installing Lean on the same machine? Or do I need to pay an additional license (and if so, am I paying that to QC or to Bloomberg)?
- Bloomberg typically throttles data access through their Desktop API, limiting the total number of data points that can be accessed in a day to 500,000. Is the QC/Lean integration subject to those limits?
- If I want to trade with Bloomberg EMSX, do I also use a local Lean install on the same PC or is that something that runs in QC's cloud?
- Does Bloomberg EMSX support a paper trading feature?
- Do I need an Institutional-level QC account for either/both of these?
Thanks.

Hi David Avraamides,
If you already have a Bloomberg account, you can use it without any further charges with Lean locally other than acquiring the Bloomberg EMSX Router & Data add-on.
All data accessed via the Bloomberg Desktop API must remain on the host computer. The Bloomberg Terminal and the LEAN instance must be on the same computer.
Yes.
Yes, the Bloomberg/Lean integration is an add-on service for institutional account holders.
For the other queries, please get in touch with support@quantconnect.com.
Best,
