Brokerages

Terminal Link supports trading the following asset classes:

You may not be able to trade all assets with Terminal Link. For example, if you live in the EU, you can't trade US ETFs. Check with your local regulators to know which assets you are allowed to trade. You may need to adjust settings in your brokerage account to live trade some assets.

Terminal Link lets you source a live data feed from the Bloomberg™ Terminal for live trading. You also can use the LEAN paper trading functionality to test your strategy on Bloomberg™’s live data feed.

When LEAN taps into Bloomberg™ via Terminal Link, it can run backtests and research notebooks with rich historical data sourced from the Bloomberg™ Terminal. LEAN provides accurate slippage, spread, and transaction fee models for realistic backtesting. All models are customizable to adapt to your strategy requirements. Historical data is cached locally in an efficient format for quick backtesting in the LEAN engine. If you request intraday historical data, you can request data from within the last 6 months. Historical open interest and custom data isn't available.
