Brokerages

Terminal Link supports trading the following asset classes:

• Equities
• Equity Options
• Futures
• Index Options

Terminal Link with the LEAN CLI lets you source historical data from Bloomberg and save it onto your desktop computer for backtesting as within your license permissions from Bloomberg. The Bloomberg API includes up to six months of history in low resolutions like second and minute resolutions.

Terminal Link enables you to create and manage Bloomberg™ orders. You can also use the LEAN CLI with the Terminal Link integration to test paper trading with LEAN. In this case, LEAN models order fills using the live tick data feed from Bloomberg™.

Order Types

The following table describes the available order types for each asset class that Terminal Link supports:

Order Type	Equity	Equity Options	Futures	Index Options
MarketOrder
LimitOrder
StopMarketOrder
StopLimitOrder

Time In Force

Terminal Link supports the following TimeInForce instructions:

• Day
• GoodTilCanceled
• GoodTilDate

Get Open Orders

Terminal Link lets you access open orders.

Monitor Fills

Terminal Link allows you to monitor orders as they fill through order events.

Updates

Terminal Link doesn't support order updates.

Cancellations

Terminal Link enables you to cancel open orders.

Handling Splits

If you're using raw data normalization and you have active orders with a limit, stop, or trigger price in the market for a US Equity when a stock split occurs, the following properties of your orders automatically adjust to reflect the stock split:

• Quantity
• Limit price
• Stop price
• Trigger price

Orders filled with Terminal Link are subject to the fees of the Bloomberg™ Execution Management System and your prime brokerage destination. To view how we model their fees, see Fees.

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.

Bloomberg™ is not affiliated with QuantConnect, nor does it endorse Terminal Link. QuantConnect requires a Trading Firm or Institutional license to use the Terminal Link integration.

The following rules apply:

• All users of the integration must hold a Bloomberg License to be defined as an "Entitled User".
• 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.

The following table shows the activities each of the Bloomberg technologies support:

Technology	Research	Backtesting	Paper Trading	Live Trading
Desktop API
B.PIPE

Execute the CLI commands in the following sections to interact with Terminal Link. If you need further assistance, see the CLI Reference.

Run Local Backtests

Launch local backtests with data from the Bloomberg Terminal Desktop API. Lean automatically fetches the data required for your backtest.

$ lean backtest "<projectName>" --data-provider-historical "Terminal Link"

Launch Research Notebooks

Start Jupyter Research Notebooks, tapping into the entire QuantConnect API with the data sourced from a Bloomberg Terminal.

$ lean research "<projectName>" --data-provider-historical "Terminal Link"

Deploy Live Algorithms

Launch live trading algorithms to trade with any of the 1300+ routing destinations in the Bloomberg EMSX network.

$ lean live "<projectName>" --brokerage "Terminal Link" --data-provider-live "Terminal Link"

You need to install the Bloomberg Terminal and the BBComm component from the Bloomberg website before you can deploy local algorithms with Terminal Link.

Follow these steps to start local live trading with the Terminal Link brokerage:

1. Open a terminal in the organization workspace that contains the project.
2. Run lean live "<projectName>" to start a live deployment wizard for the project in . / <projectName> and then enter the brokerage number, 10.

   $ lean live "My Project"
   Select a brokerage:
   1) Paper Trading
   2) Interactive Brokers
   3) Tradier
   4) OANDA
   5) Bitfinex
   6) Coinbase Advanced Trade
   7) Binance

8. View the result in the <projectName> / live / <timestamp> directory. Results are stored in real-time in JSON format. You can save results to a different directory by providing the --output <path> option in step 2.

If you already have a live environment configured in your Lean configuration file, you can skip the interactive wizard by providing the --environment <value> option in step 2. The value of this option must be the name of an environment which has live-mode set to true.

You need to set up the Bloomberg SAPI before you can deploy cloud algorithms with Terminal Link.
