LEAN can now connect to the Bloomberg™ Desktop API (DAPI),* thanks to the plug-in that we refer to as “Terminal Link.” The product is in no way affiliated with or endorsed by Bloomberg™; it is simply an add-on. When LEAN taps into Bloomberg™ via Terminal Link, it can run backtests and research notebooks from data sourced from the Bloomberg™ Terminal. After years of optimization, LEAN achieves up to millions of bars per second in event-driven backtesting.
Research
Perform research using the latest machine-learning libraries, then backtest and live trade the same code in LEAN when you use Terminal Link to facilitate compatibility between LEAN and the Bloomberg™ DAPI.
Historical Data Caching Technology
Cache data locally in an efficient format for quick backtesting in the LEAN engine. After years of optimization LEAN achieves up to millions of bars per second in event-driven backtesting.
High-Fidelity Backtest Modeling
LEAN provides accurate slippage, spread, and transaction fee models for realistic backtesting. All models are customizable to adapt to your strategy requirements.
QuantConnect's LEAN Terminal Link allows you to route orders to any of the 1,300+ liquidity pools in the Bloomberg EMSX™ network. You also can use the LEAN paper-trading functionality to test your strategy on Bloomberg™’s live data feed. Bloomberg™ is not affiliated with QuantConnect, nor does it in any way endorse Terminal Link.
Seven Asset Classes Supported
All LEAN asset classes supported through to live trading including US Equities, Equity Options, Futures, Future Options, Crypto, and Spot Forex. Advanced backtest asset modeling keeps your backtesting code identical through to production trading.
Historical Data Integration
