Terminal Link: A Game-Changer
Every QuantConnect initiative has the same goal: empowering quants. We’ve been quietly working on another project that will disrupt the status quo and further that goal. Now we’re excited to announce that QuantConnect has created a plug-in that renders our powerful LEAN engine compatible with the Bloomberg™ Desktop API (DAPI). We call this specific plug-in “Terminal Link,” though our community will call it a game-changer. Bloomberg™ is not affiliated with QuantConnect, nor does it in any way endorse Terminal Link.

Access Prime Brokerages with LEAN
The Bloomberg™ “Execution and Order Management Network” (EMSX™) is a trade routing technology that connects to 1,300+ liquidity pools and prime brokerages via a FIX connection. LEAN users with a Bloomberg™ Terminal and Desktop API (DAPI) permissions can now harness more brokers and liquidity pools by using the QuantConnect Terminal Link plug-in to make the two products compatible.
Quant Research on an Independent Platform
When Terminal Link facilitates the combined use of LEAN and DAPI, it provides access to research notebooks, point-in-time backtesting, live trading, and parameter optimization for desktop quantitative research. Standard Bloomberg™ data compliance requirements apply. See below for details.
- Use your Bloomberg™ data access to do quantitative jupyter research with LEAN’s API
- Backtest, optimize, and trade on LEAN, with data sourced from the Bloomberg™ DAPI
- Route trades to the EMSX™ network via Terminal Link
Choosing LEAN for your fund’s algorithmic trading engine ensures you are free to move to other data sources and order routing networks. Avoid vendor lock-in simply by swapping out the Terminal Link plug-in for any other in the QuantConnect ecosystem. The radically open-source nature of LEAN gives you the freedom to adapt and extend LEAN to meet your fund’s needs.
Get Started
Be one of the first 100 subscribers to Terminal Link, and your subscription will be just $1 per month through December 31, 2021. In April 2022, subscriptions will renew at the standard rate of $325 per month.
To get started navigate to the pricing page and select “Build Your Own Pack” to add the Terminal Link to your organization account. Navigate down to the modules and you’ll see the Terminal Link module.

When you add this module to your plan it will be available to use with the LEAN CLI. If you’re not familiar with the LEAN CLI – watch our introduction video, it brings the best of local and cloud development with a simple open-source pip package.
We’re excited to pioneer an independent, open-source algorithmic trading technology for our community, and are grateful for your continued support.
Happy trading.
